Description

  The present invention relates to a monitoring system, a monitoring apparatus, a monitoring method, and a program for monitoring and collecting information on a device to be monitored.

Conventionally, a monitoring system has been widely used as a system that monitors and collects the state of a device to be monitored (for example, a server). The main purpose of this monitoring system is to monitor the operating state of a server or the like, and perform alerts (detection of abnormal conditions), logging (recording of conditions), and the like.
Hereinafter, an overview of a conventional monitoring system will be described with reference to FIG. FIG. 15 is a block diagram showing an example of the configuration of a conventional monitoring system.

As shown in the figure, the conventional monitoring system includes a monitoring device 100 that performs monitoring and a plurality of monitoring targets 200. Note that each monitoring target 200 includes, for example, a server.
The monitoring apparatus 100 performs polling monitoring for each monitoring target 200 as follows.

First, the monitoring device 100 accesses the monitoring target 200, establishes a connection, and logs in after authentication. For example, the monitoring target 200 is logged in with SSH (Secure Shell).
Next, the monitoring apparatus 100 collects information from the monitoring target 200 via the established connection. For example, desired information is collected by executing various commands with SSH.
When the information collection is completed, the monitoring apparatus 100 disconnects from the monitoring target 200 and logs out.
The monitoring apparatus 100 repeats this operation for each monitoring target 200.

In such a conventional monitoring system, it is necessary to log in and log out each time the monitoring target 200 is monitored, so that the load is large. In particular, the authentication load (login load) at the time of login is large and has been regarded as a problem.
In addition, when it becomes a large-scale monitoring system that monitors a large number of monitoring targets 200, switching to each monitoring target 200 occurs frequently, so that login loads and the like are accumulated, and a long time is required for overall monitoring.
As a result, the monitoring execution cycle for each monitoring target 200 becomes longer, and it is not possible to deal with quick alerts and detailed logging, which makes it impossible to monitor with sufficient accuracy.

In addition, an invention that can reduce such a login load and perform high-speed monitoring is also disclosed (for example, see Patent Document 1).
In the invention of Patent Document 1, a connection is prepared for each monitoring target, and monitoring is performed while maintaining each logged-in connection. That is, when logging in to each monitoring target for the first time, polling monitoring can be performed without log-in processing thereafter, so there is no login load and high-speed monitoring can be performed.
That is, the monitoring target can be monitored in a short cycle, and alerting and logging are performed with sufficient accuracy.

Japanese Unexamined Patent Publication No. 2000-137888 (page 3-4, FIG. 1)

However, in the technique of monitoring while maintaining the connection as in the invention of Patent Document 1 described above, a resource such as a socket and a memory (that is, a monitoring resource) is required for each connection.
For this reason, when the number of monitoring targets increases, a large amount of monitoring resources are required. Therefore, when a large-scale monitoring system is used, monitoring may not be possible due to resource limitations.

It is a block diagram which shows the structure of the conventional monitoring system.

First, the operation of the present invention will be described.
The present invention does not always monitor every monitoring target frequently in a short cycle, but only in a short cycle when an abnormality is likely to occur (due to an alert) or a state is likely to change (due to logging). Monitor. As a result, quick alerting and fine-grained logging that are the purpose of monitoring can be performed, and monitoring with sufficient accuracy can be performed.
That is, an appropriate monitoring cycle is determined based on information fluctuation in the monitoring target, and an appropriate connection method is selected from this monitoring cycle. In other words, depending on the status of the monitoring target, the monitoring by connection every time, which is low speed and low resource consumption, and the monitoring by connection maintenance, which is high speed and high resource consumption, are dynamically switched. As a result, both sufficiently accurate monitoring and low resources can be achieved.

  Such an operation will be specifically described below with reference to FIG. A case where the state of the monitoring target (monitoring information) varies as shown in the graph of FIG. 1A will be described as an example.

  In the conventional monitoring system, as shown in FIG. 1B, monitoring is always performed with a short cycle (interval indicated by a vertical line below the graph). That is, short cycle monitoring is performed, logging can be performed as indicated by the bold line graph in the figure, and an alert can be performed when the alert threshold is exceeded. Nevertheless, in the conventional monitoring system, since a short cycle monitoring is always performed while maintaining the connection, a large amount of monitoring resources are required.

On the other hand, in this invention, as shown in FIG.1 (c), it monitors by changing a period dynamically according to the fluctuation | variation of monitoring information. That is, in the period T1 where the fluctuation is not severe, monitoring is performed with a long cycle (long cycle monitoring), and in the period T2 where the fluctuation is severe, monitoring is performed with a short period.
In addition, in the present invention, when performing the long cycle monitoring as in the period T1, the monitoring is performed every time when the resource consumption is low, and when performing the short cycle monitoring as in the period T2, the resource consumption is reduced. Monitor with a large connection maintained. Thereby, the total resource consumption can be kept lower than that of the conventional monitoring system.
Also, in the present invention, logging is performed as shown by the thick line graph in FIG. 1 (c), but this shape is almost the same as the shape in FIG. 1 (b) and is equivalent to the conventional monitoring system. Logging is possible. Furthermore, in the present invention, when the fluctuation of the period T2 in FIG. 1C is severe, it is possible to perform finer logging than the conventional monitoring system.
Further, when the monitoring information exceeds the alert threshold, an alert can be performed quickly as in the conventional monitoring system.

Next, embodiments of the present invention will be described with reference to the drawings.
In the following, a simplified monitoring system composed of a monitoring device and a plurality of monitoring targets will be described as an embodiment. However, a predetermined network environment is interposed between the monitoring device and each monitoring target. It shall be. That is, the monitoring apparatus and each monitoring target can communicate with each other via a network environment (whether wired or wireless) such as the Internet, a dedicated line, or a LAN.
Moreover, although a server etc. are demonstrated as an example of a monitoring target apparatus, it is not restricted to this, Various information processing apparatuses can be similarly set as a monitoring target.
That is, the following embodiments are for explanation, and do not limit the scope of the present invention. Therefore, those skilled in the art can employ embodiments in which each or all of these elements are replaced with equivalent ones, and these embodiments are also included in the scope of the present invention.

First, a first embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 2 is a block diagram showing the configuration of the monitoring system according to the first embodiment of the present invention. As shown in the figure, the monitoring system according to the first embodiment of the present invention includes a plurality of monitoring targets 80 and a monitoring device 10 that performs polling monitoring on each monitoring target 80.
Note that each monitoring target 80 is, for example, a server or the like that is operating to execute a predetermined process.

The monitoring device 10 includes a monitoring execution unit 11, a setting information storage unit 12, a cycle determination unit 13, and a connection selection unit 14.
Note that the monitoring device 10 includes, for example, a computer having a calculation unit (eg, a CPU), a storage unit (eg, RAM, ROM, hard disk, etc.), and a communication unit (eg, NIC). . Then, a calculation unit that operates based on a program or the like stored in the storage unit, or a communication unit that is controlled by the calculation unit includes the monitoring execution unit 11, the setting information storage unit 12, the cycle determination unit 13, and the connection selection. It functions as the means 14.

The monitoring execution unit 11 collects information by accessing the monitoring target 80 using a selected connection method (connection method to the target) described later in a determined monitoring cycle (monitoring cycle) described later.
The setting information storage unit 12 stores information necessary for determining the monitoring cycle.
The cycle determination unit 13 determines an appropriate monitoring cycle based on the information stored in the setting information storage unit 12.
The connection selection unit 14 selects an appropriate connection method based on the monitoring cycle determined by the cycle determination unit 13.

  The operation of the monitoring system (monitoring device 10) having such a configuration will be described with reference to FIG. FIG. 3 is a flowchart showing the operation of the monitoring apparatus 10 according to the first embodiment of the present invention.

As shown in FIG. 3, first, the cycle determination unit 13 reads necessary information from the setting information storage unit 12, and determines an appropriate monitoring cycle for each monitoring target 80 based on the information (step S101).
Specifically, the cycle determining means 13 determines the monitoring cycle based on the setting information as shown in FIG. This setting information is an example of information stored in the setting information storage unit 12.
As an example, the setting information in FIG. 4 includes information on a monitoring target ID, time, and a monitoring cycle. These are information for determining the monitoring cycle according to the time for each monitoring target 80. For example, the state (information) change in the actual monitoring target 80 according to the time is appropriately analyzed and obtained. It is a thing. Note that such setting information is not limited to statically determined information in advance, and may be dynamically changed (updated) from the real-time state of the monitoring target 80 or the like.

Using such setting information, the cycle determination unit 13 reads the monitoring cycle corresponding to the current time for the monitoring target 80 (monitoring target ID), and determines the monitoring cycle as an appropriate monitoring cycle for the monitoring target 80. To do.
In the present embodiment, the setting information including the correspondence between the time and the monitoring cycle as shown in FIG. 4 is used. However, the present invention is not limited to this, and setting information having other contents may be used. . For example, the present invention can be applied as appropriate when setting information including correspondence between specific conditions and monitoring cycles is used. That is, the setting information storage unit 12 may store setting information that determines a short cycle when a certain event occurs or always sets a specific monitoring target 80 as a short cycle.

Returning to FIG. 3, the connection selecting unit 14 selects a connection method based on the monitoring cycle determined by the cycle determining unit 13 (step S <b> 102). For example, the connection selection unit 14 selects either the low speed but low resource consumption every time connection or the high speed but high resource consumption connection maintenance as the connection method.
Basically, connection maintenance is suitable if the monitoring period is short, and conversely, connection is suitable every time if the monitoring period is long. For this reason, the connection selection unit 14 determines a certain period as a threshold value, and selects connection maintenance if the determined monitoring period is shorter than the threshold value, and conversely selects connection every time the monitoring period is longer than the threshold value.

Note that such a connection method selection method is an example, and the present invention is not limited to this. In addition, for example, the connection selection unit 14 may select up to a specific number among all the monitoring targets 80 in the order of the determined monitoring period as connection maintenance, and select the rest as connections every time. This is to keep resources consumed for maintaining the connection below a certain level.
In addition to these, even in a situation where the connection has been continuously maintained for a certain number of times in the past, the connection selection means 14 may select the connection to be maintained even if it becomes a condition of connection once every time. Good. This is because, when the connection is maintained for a long time, the connection condition of about once is considered to be noise, and it is highly likely that the connection will be maintained again after the next time.
Further, as an exception, the specific monitoring target 80 may be selected to always maintain connection or always connect. This is because a suitable connection method may be fixedly determined for the specific monitoring target 80.

Finally, the monitoring execution means 11 performs monitoring by the selected connection method in the determined monitoring cycle, and collects information (step S103). That is, the target monitoring target 80 is accessed in the determined monitoring cycle by the selected connection method, and information is collected.
An example of the detailed operation of the monitoring execution unit 11 will be described in more detail with reference to FIG. FIG. 5 is a flowchart showing the operation of the monitoring execution means 11. This operation is executed for each monitoring cycle as an example.

As shown in FIG. 5, first, the monitoring execution unit 11 determines whether the selected monitoring connection method is connection maintenance or connection every time (step S111).
In the case of monitoring by connection maintenance, the monitoring execution unit 11 determines whether or not the connection to the monitoring target 80 is already maintained (step S112).

Here, if the connection is already maintained (step S112; Yes), the monitoring execution unit 11 diverts the connection to the monitoring target 80 (step S113).
On the other hand, if the connection is not maintained (step S112; No), the monitoring execution unit 11 newly establishes a connection with the monitoring target 80 (step S114).

Next, the monitoring execution unit 11 uses the connection to access the monitoring target 80, collects information, and records it (step S115).
Finally, the monitoring execution unit 11 maintains the connection (step S116).

  Further, when the determination in step S111 described above is monitoring by connection every time, the monitoring execution unit 11 determines whether or not the connection to the monitoring target 80 is already maintained (step S117).

Here, if the connection is already maintained (step S117; Yes), the monitoring execution unit 11 diverts the connection to the monitoring target 80 (step S118).
On the other hand, if the connection is not maintained (step S117; No), the monitoring execution unit 11 newly establishes a connection with the monitoring target 80 (step S119).

Next, the monitoring execution unit 11 uses the connection to access the monitoring target 80, collects information, and records it (step S120).
Finally, the monitoring execution unit 11 disconnects the connection (step S121).

The monitoring apparatus 10 repeats the operations of FIGS. 3 and 5 to access each monitoring target 80 and collect information.
That is, by operating in this way, the monitoring device 10 performs monitoring in a monitoring cycle suitable for each monitoring target 80 based on the stored setting information by a connection method corresponding to the monitoring cycle. In other words, monitoring is performed while switching between monitoring by connection maintenance that is high speed but high resource consumption and monitoring by connection each time that is low speed but low resource consumption in a monitoring cycle suitable for each monitoring target 80.

In this embodiment, it is assumed that the access is to log in directly to the monitoring target 80 using SSH or the like, but is not limited to this as long as it is a connection type protocol.
For example, the configuration is such that a monitoring agent exists on each monitoring target 80, and the present invention can be applied as appropriate even when accessing via the monitoring agent.

  In this embodiment, every time monitoring is performed, the monitoring cycle is determined and the connection method is selected. However, these determinations are not made each time, and the previously determined results are diverted. Also good.

  In the present embodiment, how the monitoring apparatus 10 performs monitoring is described in an easy-to-understand manner. For this reason, explanation of means for performing alerting and logging using the monitoring result is omitted, but the monitoring apparatus 10 includes such means.

As described above, the monitoring system according to the first embodiment of the present invention is configured to connect the monitoring cycle suitable for each monitoring target 80 based on the setting information to the appropriate speed and resource consumption according to the monitoring cycle. Can be monitored.
For this reason, it is possible to perform monitoring with sufficient resources for alerting and logging, and with less resources than the conventional monitoring system that always monitors in a short cycle.
As a result, monitoring can be performed with sufficient accuracy without consuming a large amount of monitoring resources.

Next, a second embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 6 is a block diagram showing a configuration of a monitoring system according to the second embodiment of the present invention. As shown in the figure, the monitoring system according to the second embodiment of the present invention includes a plurality of monitoring targets 80 and a monitoring device 20 that performs polling monitoring on each monitoring target 80. Each monitoring target 80 is a server or the like as in the first embodiment described above.

The monitoring device 20 includes a monitoring execution unit 21, a monitoring information storage unit 22, a cycle determination unit 23, and a connection selection unit 24.
Note that the monitoring device 20 also includes a computer having a calculation unit, a storage unit, a communication unit, and the like, similarly to the monitoring device 10 (first embodiment) described above. A calculation unit that operates based on a program or the like stored in the storage unit, or a communication unit that is controlled by the calculation unit includes the monitoring execution unit 21, the monitoring information storage unit 22, the cycle determination unit 23, and the connection selection. It functions as the means 24.

The monitoring execution means 21 accesses the monitoring target 80 using the selected connection method in the determined monitoring cycle and collects information.
The monitoring information storage unit 22 stores information collected by the monitoring execution unit 21.
The period determining unit 23 analyzes the fluctuation of the information stored in the monitoring information storage unit 22 and determines an appropriate monitoring period.
The connection selection unit 24 selects an appropriate connection method based on the monitoring cycle determined by the cycle determination unit 23.

  The operation of the monitoring system (monitoring device 20) having such a configuration will be described with reference to FIG. FIG. 7 is a flowchart showing the operation of the monitoring apparatus 20 according to the second embodiment of the present invention.

As shown in FIG. 7, first, the monitoring execution unit 21 monitors the monitoring target 80 with the standard setting, collects information, and records it (step S201). That is, the monitoring target 80 is accessed with a standard monitoring cycle and connection method, information is collected and stored in the monitoring information storage unit 22. Hereinafter, the information stored in the monitoring information storage unit 22 in this way is referred to as monitoring information.
This monitoring information is information for indicating the operating state of the monitoring target 80, and as an example, the usage rate of the CPU that controls the server, the usage rate of the memory (physical memory, kernel memory, etc.), the number of processes and tasks, And information such as the number of error occurrences. The monitoring information is not limited to these, and can be changed as appropriate according to the processing content of the monitoring target 80 and the like.
In addition, the standard monitoring cycle and connection method are determined in advance.

Next, the cycle determining means 23 analyzes the fluctuation tendency of the monitoring information and determines the monitoring cycle (step S202). That is, the monitoring information stored in the monitoring information storage unit 22 is analyzed to determine an appropriate monitoring cycle for the monitoring target 80.
Specifically, the period determining unit 23 determines an appropriate monitoring period in consideration of whether the change in the monitoring information applies to, for example, a pattern as shown in FIG.
The purpose of monitoring is alerting and logging. In the alert, it is important whether or not the monitoring information exceeds the alert threshold. In the logging, it is important to record the fluctuation of the monitoring information without omission. For this reason, in the present embodiment, it is determined whether or not fine monitoring, that is, shortening the monitoring cycle, is performed in consideration of whether the fluctuation of the monitoring information applies to the three patterns shown in FIGS. Shall.
Hereinafter, the principle of determining the monitoring cycle will be described in more detail with reference to FIG.

FIG. 8A shows whether the monitoring information averages and is close to the alert threshold by graphs 811 and 812.
First, the average value of the graph 811 is close to the alert threshold, and in such a case, there is a high possibility that the alert threshold will be exceeded.
On the other hand, if the average value of the graph 812 is far from the alert threshold (the value is low) and the relative fluctuation tendency is the same as that of the graph 811, the possibility of exceeding the alert threshold is low.
Therefore, the period determination means 23 calculates | requires the average value of monitoring information, and determines that it is a short period, so that the difference between this average value and an alert threshold value is small, conversely, it determines that it is a long period, so that a difference is large.

FIG. 8B shows by graphs 821 and 822 whether the monitoring information fluctuates significantly.
First, in the graph 821, although the average value is far from the alert threshold (value is low), the fluctuation is severe. That is, since the variance value is large, there is a high possibility that the alert threshold will be exceeded. In addition, if the fluctuation is severe, there is a high need for frequent logging. This is because, according to the sampling theorem, fluctuation information may be lost unless it is monitored frequently.
On the other hand, the average value of the graph 822 is closer to the alert threshold than the graph 821, but the fluctuation is small. That is, since the variance value is small, the possibility that the alert threshold value is exceeded is low. Also, since there are few fluctuations, there are few problems even if you do not log frequently.
Therefore, the period determining means 23 obtains a dispersion value of the monitoring information, determines that the longer period is the shorter period, and conversely, determines the longer period as the smaller dispersion value is.

FIG. 8C shows whether or not there is a pulse-like variation in the monitoring information using graphs 831 and 832.
Compared to the graph 832, the graph 831 has almost the same average value and variance value, but has a pulse-like fluctuation and is likely to exceed the alert threshold. Also, there is a high need for frequent logging for the same reason as when fluctuations are severe.
On the other hand, the graph 832 has no pulse-like fluctuation and is unlikely to exceed the alert threshold.
Since the pulse-like fluctuation is instantaneous, it hardly affects the average value and the dispersion value, and therefore cannot be detected from the difference between the average value and the dispersion value. Therefore, the presence / absence of a pulse is determined based on the maximum amplitude value that is the absolute value of the difference between the maximum value or the minimum value of the monitoring information and the average value.
For example, the period determining unit 23 obtains the maximum amplitude value by the following formula 1, and determines the shorter period as the maximum amplitude value is larger, and conversely determines the longer period as the maximum amplitude value is smaller.

[Equation 1]
H_max = | (Max or Min) −Ave |
H_max: Maximum amplitude value Max: Maximum value of monitoring information Min: Minimum value of monitoring information Ave: Average value of monitoring information

  Note that these monitoring cycle determination methods are merely examples, and are not limited thereto.

Returning to FIG. 7, the connection selection unit 24 selects a connection method based on the monitoring cycle determined by the cycle determination unit 23 (step S203). That is, either a low speed but low resource consumption connection every time or a high speed but high resource consumption connection maintenance is selected as the connection method.
Since the operation of the connection selection unit 24 is the same as the operation of the connection selection unit 14 (first embodiment) described above, detailed description thereof is omitted.

Finally, the monitoring execution means 21 performs monitoring by the selected connection method in the determined monitoring cycle, and collects information (step S204). In other words, information is collected by accessing the target monitoring target 80 by the selected connection method in the determined monitoring cycle.
Since the operation of the monitoring execution unit 21 is the same as the operation of the monitoring execution unit 11 (first embodiment) except that the collected information is stored in the monitoring information storage unit 22, detailed description thereof is omitted. To do.
And the monitoring apparatus 20 returns a process to step S202, and performs the process of step S202-S204 mentioned above.

The monitoring apparatus 20 repeats such an operation of FIG. 7 to access each monitoring target 80 and collect information.
That is, by operating in this way, the monitoring device 20 automatically sets a monitoring cycle suitable for each monitoring target 80 based on the current information of each monitoring target 80 by a connection method corresponding to the monitoring cycle. Monitor. In other words, monitoring is performed while switching between monitoring by connection maintenance that is high speed but high resource consumption and monitoring by connection each time that is low speed but low resource consumption in a monitoring cycle suitable for each monitoring target 80.
Therefore, the present embodiment is further characterized in that a monitoring cycle suitable for each monitoring target 80 is automatically determined based on the information of each monitoring target 80 collected by monitoring.

  As described above, the monitoring system according to the second embodiment of the present invention is automatically suitable for each monitoring target without setting selection information in advance in addition to the effects obtained in the first embodiment described above. Monitoring can be performed in a monitoring method with a connection method of appropriate speed and resource consumption according to the monitoring cycle.

Next, a third embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 9 is a block diagram showing a configuration of a monitoring system according to the third embodiment of the present invention. As shown in the figure, the monitoring system according to the third embodiment of the present invention includes a plurality of monitoring targets 80 and a monitoring device 30 that performs polling monitoring on each monitoring target 80. Each monitoring target 80 is a server or the like as in the above-described embodiment.

The monitoring device 30 includes a monitoring execution unit 31, a monitoring information storage unit 32, a fluctuation prediction unit 33, a cycle determination unit 34, and a connection selection unit 35.
Note that the monitoring device 30 also includes a computer having a calculation unit, a storage unit, and a communication unit, as in the above-described embodiment. A calculation unit that operates based on a program or the like stored in the storage unit, or a communication unit that is controlled by the calculation unit includes the monitoring execution unit 31, the monitoring information storage unit 32, the fluctuation prediction unit 33, and the cycle determination unit 34. , And function as connection selection means 35.

The monitoring execution means 31 accesses the monitoring target 80 by the selected connection method in the determined monitoring cycle and collects information.
The monitoring information storage unit 32 stores the monitoring information collected by the monitoring execution unit 31.
The fluctuation prediction unit 33 predicts future fluctuations in the monitoring target 80 from the monitoring information stored in the monitoring information storage unit 32.
The period determining unit 34 analyzes the variation predicted by the variation predicting unit 33 and determines an appropriate monitoring period.
The connection selection unit 35 selects an appropriate connection method based on the monitoring cycle determined by the cycle determination unit 34.

  The operation of the monitoring system (monitoring device 30) having such a configuration will be described with reference to FIG. FIG. 10 is a flowchart showing the operation of the monitoring apparatus 30 according to the third embodiment of the present invention.

As shown in FIG. 10, first, the monitoring execution means 31 monitors the monitoring target 80 with standard settings, collects information, and records it (step S301). That is, the monitoring target 80 is accessed with a standard monitoring cycle and connection method, and monitoring information is collected and stored in the monitoring information storage unit 32.
The standard monitoring cycle and connection method are determined in advance.

Next, the fluctuation prediction means 33 predicts future fluctuations from the monitoring information stored in the monitoring information storage means 32 (step S302).
Note that the monitoring information is time-series data, and examples of such time-series data prediction methods include the least square method and the moving average method. Therefore, the fluctuation prediction means 33 predicts the future value of the monitoring information using a prediction method such as a least square method or a moving average method.
As an example, the case where the fluctuation prediction means 33 predicts the future value of the monitoring information by the least square method will be described with reference to FIG. FIG. 11 is a schematic diagram for explaining the principle of the prediction method based on the least square method.

As shown in FIG. 11, in the least square method, the past n values of time series data are used as samples, and the tendency of those samples is approximated by a specific approximation function f (t). The value f (tx) of the future (time tx) is predicted on the assumption that the behavior is close to the approximate function.
This approximate function f (t) is determined so that the sum of squares of the difference between f (t) and the value of each sample is minimized.
Therefore, the fluctuation prediction unit 33 uses the past n pieces of monitoring information stored in the monitoring information storage unit 32 as samples, approximates these samples with an approximation function, and predicts future values of the monitoring information.
In addition, the prediction method by such a least square method is an example, and is not limited to this. That is, the fluctuation prediction unit 33 may predict the future value of the monitoring information by a prediction method such as a moving average method.

Returning to FIG. 10, the cycle determination unit 34 analyzes the fluctuation tendency of the monitoring information predicted by the fluctuation prediction unit 33 and determines the monitoring cycle (step S303). That is, a monitoring cycle appropriate for the monitoring target 80 is determined by analyzing changes in the monitoring information.
Since the operation of the period determining unit 34 is the same as the operation of the period determining unit 23 (second embodiment) except that the analysis target is predicted monitoring information, detailed description thereof is omitted. .

Next, the connection selection unit 35 selects a connection method based on the monitoring cycle determined by the cycle determination unit 34 (step S304). That is, either a low speed but low resource consumption connection every time or a high speed but high resource consumption connection maintenance is selected as the connection method.
Since the operation of the connection selection unit 35 is the same as that of the connection selection unit 14 and the like described above, detailed description thereof is omitted.

Finally, the monitoring execution means 31 performs monitoring by the selected connection method in the determined monitoring cycle, and collects information (step S305). In other words, information is collected by accessing the target monitoring target 80 by the selected connection method in the determined monitoring cycle.
Since the operation of the monitoring execution unit 31 is the same as the operation of the monitoring execution unit 21 (second embodiment) described above, detailed description thereof is omitted.
And the monitoring apparatus 30 returns a process to step S302, and performs the process of step S302-S305 mentioned above.

The monitoring device 30 repeats such an operation of FIG. 10 to access each monitoring target 80 and collect information.
That is, by operating in this way, the monitoring device 30 predicts future information fluctuations of each monitoring target 80 and automatically sets the monitoring period suitable for each monitoring target 80 based on the predicted value. Monitoring is performed using a connection method according to the cycle. In other words, monitoring is performed while switching between monitoring by connection maintenance that is high speed but high resource consumption and monitoring by connection each time that is low speed but low resource consumption in a monitoring cycle suitable for each monitoring target 80.
Therefore, this embodiment is further characterized in that a monitoring cycle suitable for each monitoring target is automatically determined in anticipation of future monitoring information fluctuations, not current monitoring information fluctuations.

  As described above, the monitoring system according to the third embodiment of the present invention can perform monitoring suitable for future fluctuations in addition to the effects obtained in the second embodiment described above, and thus is necessary for alerting and logging. The possibility of missing the fluctuation information can be reduced.

Hereinafter, the information stored in the collected information storage unit 92 in this way is referred to as collected information. Note that this collected information is equivalent to information collected by the monitoring execution means 41 of the monitoring device 40, as will be described later.

Next, the fluctuation prediction means 93 predicts future fluctuations from the collected information stored in the collected information storage means 92 (step S402).
The operation of the fluctuation prediction unit 93 is the same as the operation of the fluctuation prediction unit 33 (third embodiment) described above except that the analysis target is collected information, and detailed description thereof is omitted.

Next, the cycle determining unit 94 analyzes the variation tendency of the collected information predicted by the variation predicting unit 93 and determines a monitoring cycle (step S403). That is, the monitoring period suitable for the monitoring target 90 (self) is determined by analyzing the fluctuation of the collected information.
The operation of the cycle determining unit 94 is the same as the operation of the cycle determining unit 34 (third embodiment) described above except that the analysis target is collected information, and detailed description thereof is omitted.
And the monitoring object 90 returns a process to step S401, and performs the process of step S401-S403 mentioned above.

  Next, the operation of the monitoring device 40 will be described with reference to FIG. FIG. 14 is a flowchart showing the operation of the monitoring device 40 according to the fourth embodiment of the present invention.

  As shown in FIG. 14, first, the monitoring execution means 41 monitors the monitoring target 90 with the standard setting and collects information. At that time, the monitoring period is also collected (step S411). That is, the monitoring target 90 is accessed by the standard monitoring cycle and connection method, and information including the monitoring cycle determined by the cycle determination means 94 of the monitoring target 90 is collected.

Next, the connection selection unit 42 selects a connection method based on the collected monitoring cycle (step S412). That is, either a low speed but low resource consumption connection every time or a high speed but high resource consumption connection maintenance is selected as the connection method.
The operation of the connection selection unit 42 is the same as the operation of the connection selection unit 14 and the like described above, and detailed description thereof is omitted.

Finally, the monitoring execution means 41 performs monitoring by the selected connection method in the determined monitoring cycle and collects information. At that time, the monitoring period is also collected (step S413). That is, the target monitoring target 90 is accessed by the selected connection method in the determined monitoring cycle, and information including the monitoring cycle is collected.
The operation of the monitoring execution unit 41 is the same as the operation of the monitoring execution unit 21 and the like described above except that the monitoring period is collected at the same time, and detailed description thereof is omitted.

The monitoring device 40 repeats such an operation of FIG. 14 to access each monitoring target 90 and collect information including a monitoring cycle.
In other words, by operating in this way, the monitoring device 40 collects monitoring cycles suitable for future information fluctuations, which are predicted in a distributed manner for each monitoring target 90, and sets the connection method according to the monitoring cycle. To monitor. That is, the monitoring is performed while switching between the monitoring by the connection maintenance that is high speed but high resource consumption and the monitoring by the connection that is low speed but low resource consumption each time in a monitoring cycle suitable for each monitoring target 90.

Therefore, in a case where integrated connection selection is not performed, for example, when connection selection is performed with a threshold for a single monitoring cycle, such connection selection may be distributed to each monitoring target 90.

Further, in the present embodiment, a case has been described in which the fluctuation prediction unit 93 predicts future fluctuations in collected information in the monitoring target 90 and the period determination unit 94 analyzes the prediction result to determine the monitoring period. The configuration for performing the fluctuation prediction may be omitted.
That is, the cycle determining unit 94 analyzes the variation of the collected information stored in the collected information storage unit 92 and determines the monitoring cycle of the monitoring target 90 (self) as in the second embodiment described above. Also good.

As described above, the monitoring system according to the fourth embodiment of the present invention can distribute processing to the monitoring target side in addition to the effects obtained in the third embodiment described above, and the load is not concentrated on the monitoring device side.
