Abstract

PROBLEM TO BE SOLVED: To monitor trouble and a stop of a monitored system without any misrecognition. SOLUTION: The object monitored system 2 sends a different alarm to a monitor server 3 when the cause of a start, a stop, and other trouble is unknown. The monitor server 3 sends a monitor message and confirms whether there is an answer message from the monitored system (31). When there is no answer message, a flag showing the operation state of the system is referred to and when the flag shows a system-actuation, a trouble occurrence message is displayed (32). Further, the monitor server 3 has an alarm kind decision means 33 which decides the kind of the alarm received form the monitored system and a flag setting means 34 which sets a start or stop flag of the system in a flag setting area when the decided alarm kind is an actuation kind or stop kind, and displays the trouble occurrence message (35) when the kind is another alarm kind and the start flag is set in the flag setting area.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring device and a program for monitoring a failure occurrence state of a monitoring target system (hereinafter, including a monitoring target device) such as a computer system.

[0002]

2. Description of the Related Art When remotely monitoring the failure occurrence state of a system to be monitored such as a computer system, the following two types of monitoring methods are used.

One of the methods is a method in which a computer system, which is a system to be monitored, detects a failure of itself and detects an error message generated by the monitoring server. Although the computer system is not stopped, this corresponds to a case where, for example, a minor failure of the HDD or the memory occurs.

The other one is that, as shown in FIG. 10, a monitoring server 51 periodically sends a monitoring message to a monitoring target system 53 via a network 52 such as a public line, and then a response is sent from the monitoring target system 53. This is a monitoring method to judge that a failure such as computer down occurs when there is no message. Such a monitoring message is also called a heartbeat message, and in the case of the Internet, a PING (Packet Internet Groper) message is often used. This PING message method is a method of designating the IP address or host name of the monitored system 53, executing a failure confirmation command, transmitting a packet, and receiving a response packet from the monitored system 53.

[0005]

By the way, of the above monitoring methods, the latter monitoring method of receiving a response message from the monitoring target system 53 not only detects the occurrence of a failure in the monitoring target system 53, but also, for example, Even if the computer is intentionally shut down for maintenance or the like, the response message cannot be received from the monitored system 53. Therefore, the monitoring server 51 is the monitoring target system 5
When the monitoring message is sent during the planned stop of No. 3, since the response message cannot be received, it is erroneously recognized as a system failure, and there is a problem that the actual failure and the planned stop cannot be clearly recognized. .

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a remote monitoring device and a program capable of clearly recognizing a failure occurrence and a planned stoppage of a monitored system.

[0007]

(1) In order to solve the above problems, a remote monitoring apparatus according to the present invention which receives at least a start alarm and a stop alarm from a monitored system and monitors the state of the monitored system. A means for transmitting a monitoring message, determining the occurrence of a failure from the presence or absence of a response message from the monitored system and a flag in a flag setting area indicating the operating state of the monitored system, and displaying a failure occurrence message; When the alarm transmitted from the system to be monitored is received and an alarm type determining means for determining the type of the alarm, and when the alarm type is a start type or a stop type by this determining means, the monitoring target is set in the flag setting area. And a flag setting means for setting a flag indicating system start or stop. It is a success.

With the above-described structure of the present invention, a start alarm is usually transmitted when the system to be monitored is started. Therefore, the alarm type determining means determines that the system is the start type and displays the flag in the flag setting area. A monitoring flag ON, which indicates that the system is activated, is set. Therefore, in this state, the monitoring server sends a monitoring message at every predetermined cycle, judges whether there is a response message from the monitoring target system within a predetermined time, and if there is no response message, the monitoring target is set in the flag setting area. If the monitoring flag ON indicating the system startup is set, it is determined that there is a failure and a failure message is displayed.

However, when the system to be monitored is a planned stop, a stop alarm is sent. Therefore, the alarm type determining means determines that the system is a stop type and turns off the monitor flag indicating the stop of the system to be monitored in the flag setting area. Therefore, even if it is confirmed that there is no response message as described above, referring to the flag setting area, since the flag indicating stop is set, it is not determined that there is a failure, and the failure message is not displayed. In other words, it is possible to clearly distinguish between the failure of the monitored system and the planned stop.

(2) A remote monitoring apparatus according to the present invention is a remote monitoring apparatus that receives a stop alarm including at least a start alarm and a scheduled work time from a monitored system and monitors the state of the monitored system. A means for transmitting a message, judging the occurrence of a failure from the presence or absence of a response message from the monitored system and a flag in a flag setting area indicating the operating state of the monitored system, and displaying a failure occurrence message; Alarm type determination means for receiving the alarm transmitted from the device and determining the type of the alarm;
When the alarm type is the start type or the stop type by this determination means, a flag setting means for setting a flag indicating the start or stop of the monitored system in the flag setting area and a flag indicating the stop in the flag setting area are set. When set, the work time display means displays the scheduled work time included in the received stop alarm.

Since the present invention is configured as described above, the stop alarm includes the scheduled work time and is transmitted. Therefore, when the alarm type determining means determines the stop type, the scheduled work time is displayed. It is possible to easily understand that the system to be monitored is in the process of maintenance and inspection, and when the maintenance work is completed.

(3) Further, in addition to the configuration of the above item (1), means for presetting a standard scheduled work time of the monitored system, and no response message from the monitored system, and the flag setting When the area flag is a flag indicating that the system is stopped, a means for displaying a warning message when the current time exceeds a preset start-up time (system stop alarm acquisition time + the standard work scheduled time), When the flag setting means sets a flag indicating that the monitored system is stopped in the flag setting area, by adding means for setting the scheduled start time, the current time exceeds the preset scheduled time. Warning message is displayed when
It can be inferred that problems such as maintenance work have occurred and it takes time.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

(First Embodiment) FIG. 1 is a system configuration diagram showing an embodiment of a remote monitoring system including a remote monitoring device according to the present invention.

This system uses a network 1 such as the Internet including a public line. On this network 1, a computer system for performing required information processing, a plurality of monitored systems 2 such as computer equipment, and the present invention are provided. A monitoring server 3, which is a related remote monitoring device, is connected.

The system to be monitored 2 incorporates a process for transmitting a "start" alarm as a part of an application or system start procedure, so that the "start" alarm is automatically transmitted when the system itself is started. ,
In addition, by incorporating a process that sends a "stop" alarm as part of the application or system stop procedure, a "stop" alarm is automatically sent when the user inputs an application or system stop instruction for maintenance or inspection. It has a function.

The monitoring server 3 has at least a monitoring status information area 4a having a flag setting area for each system name to be monitored, a message information area 4b for storing a failure occurrence message, and a monitoring information storage device 4 having other necessary files. A program storage device 5 for storing the monitoring processing program is provided. Although these storage devices 4 and 5 are described individually, they may be divided into areas and stored in one storage device.

Functionally, the monitoring server 3 sends a monitoring message such as a heartbeat at a predetermined cycle to check the presence or absence of a response message from the monitored system 2, and a response message checking means 31. It is confirmed by the means 31 that there is no response message, and the monitoring flag indicating that the monitored system 2 is already activated is set in the flag setting area corresponding to the system name of the monitored state information file 31a. The first failure message display means 32 for extracting the failure occurrence message from the message information area 4b and displaying the failure occurrence message when the failure occurrence is determined, and when the monitoring flag is other than that, the stop is determined.
And are provided.

Further, when there is a response message from the monitoring target system 2, the monitoring server 3 judges the type of the alarm if there is an alarm already being received from the monitoring target system 2, and this judgment is made. Based on the determination result by the means 33, when the monitored system 2 is the start type, the monitoring flag ON indicating that the monitored state information area 4a is being started is ON, and when the monitored system 2 is the stop type, the monitored state information area 4a is stopped When the flag setting means 34 for setting the monitoring flag OFF and the monitored system 2 are of types of unknown cause including failures other than start and stop, the monitoring flag is turned on in the monitoring status information area 4a.
If is set, the second failure message display means 35 is provided which judges that a failure has occurred and extracts and displays the failure message from the message information area 4b.

The monitoring message transmitted from the monitoring server 3 is, for example, a PING message of the Internet protocol, the response message returned from the monitored system 2 is a PING response message, and the alarm transmitted from the monitored system 2 is, for example. Internet Protocol SNMP (Simple NetworkMan)
agement Protocol) Trap message format is used.

Next, an operation of the system as described above and a series of processing examples of the monitoring processing program stored in the program storage device 32 mounted on the monitoring server 3 will be described with reference to FIG.

First, the monitored system 2 has a "start" alarm at startup, a "stop" alarm in the case of a planned stop, and a "failure" when the cause including other failures is unknown.
Automatically notify the alarm. When the monitoring server 3 receives the alarm, the monitoring server 3 stores the alarm in a predetermined appropriate storage unit together with the system identification data and the alarm reception time.

In this state, the monitoring server 3 transmits a monitoring message such as a heartbeat at a predetermined cycle, and determines whether or not a response message is received from the system 2 to be monitored within a predetermined time. (S1, S
2: Message presence / absence determination function).

If there is no response message within the predetermined time, the state of the monitor flag is judged by referring to the state of the monitor flag in the flag setting area in the monitor state information area 4a (S3), and the monitor flag is When it is ON, that is, when there is no response message within a predetermined time, and when the monitored system 2 is in the "starting" alarm state indicating that the monitored system 2 is starting up, the failure occurrence message is read from the message information area 4b and the display unit 6 When the monitoring flag is OFF, that is, when the monitored system 2 is a flag indicating stop, the failure occurrence message is not displayed. Step S
Reference numerals 3 and S4 are first failure message display functions. When the display of the failure message is cleared or when the monitoring flag is OFF, the process waits until the transmission cycle of the next monitoring message is reached (S5).

On the other hand, when there is a response message from the monitored system 2 within a predetermined time in step S2, it is determined whether or not an alarm has already been received (S6). As described above, if an alarm is stored in a predetermined appropriate storage means, it is determined that an alarm has been received, and the type of the alarm is determined (S7). When the same system identification data has a plurality of alarms, the alarm type of the latest alarm is determined. Steps S6 and S7
Is an alarm type determination function. If no alarm is received and stored, the process waits until the next monitoring message transmission cycle is reached (S5).

As a result of the determination of the alarm type in step S7, if the activation type is the "activation" alarm, the monitoring flag ON indicating that the monitored system 2 is being activated is set in the flag setting area in the monitoring status information area 4a. After setting (S8), the process proceeds to step S5. In the case of a stop type by the "stop" alarm, the monitoring target system 2 sets a monitoring flag OFF indicating a planned stop due to maintenance or inspection in the flag setting area in the monitoring status information area 4a (S9), and in step S5. Transition. Steps S8 and S
It can be said that 9 is a flag setting function.

On the other hand, in the case of an alarm other than "start" and "stop", it is judged whether the monitoring flag in the flag setting area is ON, that is, whether the monitored system 2 is being started (S10), When the monitored system 2 is being activated, the failure occurrence message is read from the message information area 31b and displayed on the display unit 33 (S11). When the monitoring flag is not ON, the failure message is not displayed.

FIG. 3 is a diagram schematically showing a series of operating states between the monitored system 2 and the monitoring server 3.

Therefore, according to the above-described embodiment, when there is no response from the monitored system 2 within a predetermined time after transmitting the monitored message from the monitored server 3, the operating state of the monitored system 2 is represented. By referring to the state of the flag, the failure occurrence message is displayed if it is being activated, and the failure occurrence message is not displayed if it is being stopped. A failure occurrence message can be displayed.

Further, when an alarm is received from the monitored system 2, it is judged whether the alarm is a "start" alarm, a "stop" alarm or another alarm, and the monitoring status information area 31a is determined according to the judged type. Since the monitoring flag is set in the flag setting area inside, it can be easily identified whether the monitored system 2 is in operation or stopped, and the flag representing the state of the monitored system 2 can be set accurately.

(Second Embodiment) FIG. 4 is a system configuration diagram showing another embodiment of a remote monitoring system having a remote monitoring device according to the present invention. Since FIG. 4 has almost the same configuration as the system shown in FIG. 1, the same parts are designated by the same reference numerals, and detailed description thereof will be omitted from the description of FIG.
Particularly different parts will be described.

This system comprises a computer system for performing required information processing on a network 1 such as the Internet including a public line, a plurality of monitoring target systems 2 such as computer equipment, and a monitoring server which is a remote monitoring device according to the present invention. 3 is the same as that of FIG. 1 in that it is connected.

First, in this system, the monitored system 2 is different. That is, the monitored system 2
The point that the "start" alarm is transmitted at the time of start-up is the same as that of the first embodiment, but is different particularly in the case of a planned stop such as maintenance inspection. In other words, in the case of a planned shutdown such as maintenance / inspection of the monitored system 2, it is common to set the scheduled maintenance work time in advance to perform the work. Therefore, when the "stop" alarm is transmitted, the "stop" alarm is generated. Send including the scheduled work time data. This scheduled work time is, for example, xx month x
X days x x hours x x minutes (maintenance end time), or x x
It means time data such as month xx day xx hour xx minute to xx hour xx minute (maintenance work period).

If necessary, the monitored system 2 sends a "fault" alarm when the cause is unknown, including faults other than start and stop.

On the other hand, the monitoring server 3 has the response message confirmation means 31, the first failure message display means 32, the alarm type determination means 33, and the flag setting means 3 as described above.
4. In addition to the second failure message display means 35, "stop"
When the alarm is received, the scheduled work time data included in the "stop" alarm is stored in any one of the information areas 4a or 4b of the monitoring information storage device 4, and the alarm type determination means 34 determines the alarm as the "stop" alarm. Then, the scheduled work time data stored in the information area 4a or 4b is read out, and the display unit 6 displays the current time together with the current time.
The work time display means 36 for displaying is displayed. 5
Reference numeral a denotes a program storage device, which stores a monitoring processing program including a display of scheduled maintenance work time.

Next, the operation of the monitoring server 3 shown in FIG. 4 and a series of processing examples of the monitoring processing program stored in the program storage device 5a installed in the monitoring server 3 will be described with reference to FIG. Since the processing in steps S1 to S6 in FIG. 5 is the same as that in FIG. 2, only the description of FIG. 2 will be given here, and processing subsequent to the case where it is determined that the alarm is received in step S6 will be described.

That is, when it is determined in step S6 that an alarm has been received, the type of the alarm is determined (21). When the same system identification data has a plurality of alarms, the alarm type of the latest alarm is determined. Steps S6 and S21 are an alarm type determination function. If no alarm is received and stored, the process waits until the next monitoring message transmission cycle is reached (S5).

The determination of the alarm type in step S21 determines at least the type of the "start" alarm or the "stop" alarm, and the types of other "fault" alarms are also determined as necessary. As a result of this alarm type determination, in the case of the “startup” type, the monitoring flag ON indicating that the monitored system 2 is being started is set in the flag setting area in the monitoring status information area 4a (S2
2), shift to step S5. In the case of the "stop" type, the monitoring flag OFF is set in the flag setting area in the monitoring status information area 4a, which indicates that the monitored system 2 is a planned stop such as a maintenance inspection (S23). It can be said that these steps S22 and S23 are flag setting functions.

By the way, in steps S22 and S23, it is determined that the type of stop is the stop flag O which is in the stopped state.
After setting the FF, the current time and information area 4a or 4
The scheduled work time data stored in b is read out and displayed on the display unit 6 (S24: work time display function).

On the other hand, in the case of a "fault" alarm of unknown cause including a fault other than "start" and "stop", is the monitoring flag in the flag setting area ON, that is, is the monitored system 2 in the activated state? It is determined whether or not (S25), when the monitored system 2 is being started, the failure occurrence message is read from the message information area 4b, and the display unit 3
3 is displayed (S26). When the monitoring flag is not ON, the failure message is not displayed.

FIG. 6 is a diagram schematically showing a series of operating states between the monitored system 2 and the monitoring server 3.

Therefore, according to the above-described embodiment, in addition to the effect similar to that described in the first embodiment, the scheduled work time is displayed so that the monitoring server 3 can monitor each monitoring target. It is possible to visually recognize the state of maintenance and inspection of the systems 2, ... And to know when the maintenance and inspection work time ends and to further improve the monitoring performance.

(Third Embodiment) FIG. 7 is a system configuration diagram showing another embodiment of a remote monitoring system having a remote monitoring device according to the present invention. Since FIG. 7 has almost the same configuration as the system shown in FIG. 1, the same parts are denoted by the same reference numerals, and the detailed description thereof will be omitted from the description of FIG.
Particularly different parts will be described.

In this embodiment, the standard maintenance work scheduled time (for example, 2 hours) is set in advance for each monitored system 2 or all the systems 2 on the monitoring server 3 side, and "stop" is performed.
After judging the alarm type, the current time (alarm reception time) +
In this example, a warning message is displayed when the scheduled maintenance work time = the scheduled start time has passed.

This remote monitoring system is a computer system for performing required information processing on a network 1 such as the Internet including a public line, a plurality of monitored systems 2 such as computer equipment, and a remote monitoring device according to the present invention. The configuration is similar to that of FIG. 1 in that the monitoring server 3 is connected.

As described above, the monitored system 2 has a "start" alarm when the system 2 is started, a "stop" alarm in the case of a planned stop such as maintenance and inspection, and other causes such as an unknown cause including a failure. Of the "fault" alarms, at least the former two alarms are sometimes automatically transmitted, as in FIG.

On the other hand, the monitoring server 3 can preliminarily monitor the standard maintenance work scheduled time for each monitoring target system 2 or for all the systems 2 when performing maintenance and inspection of the monitoring target system 2. A standard scheduled maintenance work time (for example, 2 hours) is set for each monitored system 2 or all the systems 2 in the status information area 4a or the like.

Functionally, the monitoring server 3 refers to the monitoring flag in the flag setting area when the message response confirmation means 31 for confirming the presence / absence of a response message, and the response message is confirmed, and the monitored system 2 If the monitoring flag indicating that the system is being activated is ON, the first failure message display means 32 for displaying a failure occurrence message,
If the monitoring flag indicating that the monitored system 2 is in the planned stop state is OFF, the alarm reception time + standard maintenance work scheduled time = scheduled start time is compared with the current time, and the current time is the scheduled start time. If it is determined that the maintenance work has occurred, it is determined that there is a problem in the maintenance work, and a warning message display means 37 for displaying a warning message, the alarm type determination means 33, the flag setting means 34, and the second obstacle. When the message display unit 35 and the alarm type are the stop type, after setting the monitoring flag OFF indicating that the monitored system 2 is in the planned stop state, the alarm reception time + standard maintenance work scheduled time = scheduled startup time A scheduled activation time setting means 38 for setting is set.
The warning message is stored in the message information area 4b. Reference numeral 5b is a program storage device that stores a monitoring processing program.

Next, the operation of the monitoring server 3 shown in FIG. 7 and a series of processing examples of the monitoring processing program stored in the program storage device 5b installed in the monitoring server 3 will be described with reference to FIG. Since the processing of steps S1 to S6 in FIG. 1 is the same as that of FIG. 2, only the steps other than step SS6 will be described here, omitting the description of FIG.

First, in the monitoring server 3, a standard scheduled maintenance work time is set in advance in the monitoring status information area 4a and the like.

In this state, if there is no response message (S2), and the monitoring flag is referred to (S3), and the monitoring flag is a flag indicating the stop, step S
31, the current time is compared with the scheduled activation time (= alarm reception time + standard maintenance work scheduled time), and when the current time exceeds the scheduled activation time, a warning message is read from the message information area 4b, A warning message is displayed on the display unit 6 to notify the delay state of maintenance work (S31, S32: warning message display function).

On the other hand, when it is determined in step S2 and step S6 that the response message is present and the alarm is received, the type of the alarm is determined (S3).
3). Steps S6 and S33 are an alarm type determination function.

The determination of the alarm type in step S33 determines at least the type of "start" alarm or "stop" alarm, and the type of other "fault" alarms is also determined as necessary. As a result of this alarm type determination, in the case of the “start” type, the monitoring flag ON indicating that the monitored system 2 is being activated is set in the flag setting area in the monitoring status information area 4a (S3
4) and shifts to step S5. In the case of the "stop" type, a monitoring flag OFF is set in the flag setting area in the monitoring status information area 4a, which indicates that the monitored system 2 is a planned stop such as maintenance and inspection (S35). It can be said that these steps S34 and S35 are flag setting functions.

By the way, in steps S33 and S35, the monitoring flag OFF, which is determined to be the stop type and indicates that the monitored system 2 is stopped, is set in the monitoring status information area 4a, and then the stopped monitoring is performed. The scheduled start time of the target system 2 (alarm reception time (alarm acquisition time) + standard maintenance work scheduled time) is set in the monitoring status information area 4a (S36: scheduled start time setting function).

On the other hand, in the case of a "fault" alarm of unknown cause including a fault other than "start" and "stop", is the monitoring flag in the flag setting area ON, that is, is the monitored system 2 in the activated state? It is determined whether or not (S37), when the monitored system 2 is being started, the failure occurrence message is read from the message information area 4b, and the display unit 6
(S38). When the monitoring flag is not ON,
Does not display the error message.

FIG. 9 is a diagram schematically showing a series of operating states between the monitored system 2 and the monitoring server 3.

Therefore, according to the above-described embodiment, the monitoring server 3 has the same effects as those of the first embodiment, and the standard maintenance work scheduled time for the monitored system 2 is set in advance in the monitoring information area. 4a, etc., when an alarm is received from the monitored system 2, when the alarm type is determined to be a stop type, the stop type monitoring flag is set, and the alarm reception time + standard maintenance work scheduled time = start schedule Since the time is set, when the monitoring message is sent, there is no response message, and when the stop type monitoring flag is set, it is determined whether the current time exceeds the scheduled start time, When the current time exceeds the scheduled start time, a warning message is displayed, making it easy for maintenance work to be behind the scheduled maintenance work time. It is possible to grip.

The invention of the present application is not limited to the above-described embodiment, and various modifications can be carried out without departing from the scope of the invention. Further, the respective embodiments can be implemented in combination as much as possible, and in that case, the effect of the combination can be obtained. Furthermore, each of the above-described embodiments includes various inventions of higher and lower stages,
