(A) First Embodiment Hereinafter, a first embodiment of an information collection apparatus, an information collection program, and a monitoring system according to the present invention will be described with reference to the drawings.

  In the first embodiment, for example, in a monitoring system in which the monitoring server monitors information (such as MIB information) such as an operation state or a failure state of one or a plurality of monitored devices, The case where this invention is applied is illustrated.

(A-1) Configuration of the First Embodiment FIG. 1 is a configuration diagram showing the overall configuration of the monitoring system and the internal configuration of each component according to the first embodiment.

  In FIG. 1, a monitoring system 10 according to the first embodiment includes at least a monitoring server 1A, a plurality of user terminals 2 (2-1 and 2-2), and monitored devices 3 (3-1 and 3-2). .

  The monitoring server 1A, the user terminal 2, and the monitored device 3 are connected via a network. The network may be either a dedicated network or a public network, or may be a wired line or a wireless line.

  The communication protocol is not particularly limited and can be widely applied. For example, TCP / IP can be applied as a communication protocol. In addition, the numbers of user terminals 2 and monitored devices 3 in FIG. 1 are not particularly limited, and may be three or more.

  The monitoring server 1A monitors the operational status and / or failure status of the monitored devices 3-1 and 3-2. When receiving the information acquisition request from the user terminal 2, the monitoring server 1 </ b> A makes an information acquisition request to the target monitored device 3 and collects desired information from the monitored device 3. Then, the monitoring server 1A transmits the information collected from the monitored device 3 to the requesting user terminal 2.

  Moreover, the monitoring server 1A has at least a state collection unit 11A and a communication unit 12 as its main functional configuration. Note that the monitoring server 1A has the same configuration as an existing server, and includes, for example, a CPU, a storage unit including, for example, a ROM, a RAM, and an EEPROM, and a communication unit.

  Upon receipt of the information acquisition request signal from the user terminal 2, the state collection unit 11A acquires information indicating the state of the monitored device 3 related to the information acquisition request and responds to the requesting user terminal 2. is there.

  Here, the information acquisition request signal includes at least identification information of the transmission source user terminal 2 (for example, address information of the user terminal 2) and identification information of the monitored apparatus 3 that acquires the information. In addition, the type of information to be acquired may be included.

  The state collection unit 11A includes a state collection execution unit 111, a collection state holding unit 112, and a collection state control unit 113 as its functions.

For example, the state collection execution unit 111 corresponds to an information collection thread. The state collection execution unit 111 is activated under the control of the collection state control unit 113.

  The collection state holding unit 112 holds the collection state of the activated state collection execution unit 111. That is, the collection state holding unit 112 holds the state of the information collection thread that is currently activated. Further, when the collection by the state collection execution unit 111 and the response to the request source are completed, the collection state holding unit 112 deletes the corresponding state held.

  Here, the collection state holding unit 112 holds information in which the identification information of the user terminal 2 that is the request source of the information acquisition request is associated with the identification information of the monitored device 3 that is the request destination. If the type of information to be collected can be selected, the collection state holding unit 112 may hold information including the information type.

The collection state control unit 113 controls the function of the information collection unit 11. When the collection state control unit 113 receives the information acquisition request signal, the collection state control unit 113 refers to the collection state holding unit 112 to confirm the currently activated collection state.

  Then, it is determined whether or not the state collection execution unit 111 that makes the request contents the same in the current information acquisition request is activated, and if the state collection execution unit 111 that has the same request contents is activated, the collection state The control unit 113 prevents the state collection execution unit 111 corresponding to the current information acquisition request from being activated. On the other hand, when the state collection execution unit 111 having the same request content is not activated, the collection state control unit 113 activates the state collection execution unit 111 corresponding to the current information acquisition request.

  The communication unit 12 is a processing unit or device that transmits and receives information to and from the user terminal 2 and the monitored device 3.

  The user terminal 2 (2-1 and 2-2) has, for example, a display unit, a control unit, a storage unit, a communication unit, and the like that display a Web screen indicating status information of the monitored device 3 by a Web browser function or the like. It is. As shown in FIG. 1, the user terminal 2 has at least an information acquisition request unit 21 and a communication unit 22 as its functions.

  The information acquisition request unit 21 transmits at least an information acquisition request signal including identification information of the monitored device 3 to be acquired by the user to the monitoring server 1.

  The communication unit 22 is a processing unit or device that transmits and receives information to and from the monitoring server 1A.

  The monitored devices 3 (3-1 and 3-2) are monitored by the monitoring server 1A for their operational status, failure status, and the like. In response to the acquisition request from the monitoring server 1A, the monitored device 3 transmits information on the latest operation state and failure state at that time to the monitoring server 1A. The monitored device 3 includes at least an operation state data holding unit 311 that holds operation state data, a failure data holding unit 312 having failure data, and a communication unit 32 that transmits / receives information to / from the monitoring server 1A.

(A-2) Operation of the First Embodiment Next, the operation of the information collection method in the monitoring system 10 of the first embodiment will be described with reference to the drawings.

  FIG. 3 is an explanatory diagram illustrating a flow of the information collection method according to the first embodiment. FIG. 4 is a flowchart illustrating information collection processing in the monitoring server 1A according to the first embodiment.

  In the following, an operation when the user terminal 2-1 and the user terminal 2-2 make an information acquisition request for collecting the latest information of the monitored device 3-1 at the same time is shown. For convenience of explanation, the monitored device 3-1 is also referred to as device A, and the monitored device 3-2 is also referred to as device B.

  First, as illustrated in FIG. 3, in the user terminal 2-1, the user presses a collection button for requesting collection of the state information of the device A on the Web screen (S <b> 201). Thereby, the user terminal 2-1 transmits an information acquisition request signal to the monitoring server 1A (S202).

  When the monitoring server 1A receives the information acquisition request signal from the user terminal 2-1 (S301), the collection state control unit 113 refers to the collection state holding unit 112 and confirms the current collection state data. (S203, S302).

  At this time, collection state data is not held in the collection state holding unit 112. Accordingly, the collection state control unit 113 activates the state collection execution unit 111 for the device A from the user terminal 2-1 (S303), and records the state collection data of the state collection execution unit 111 in the collection state holding unit 112. (S204, S304).

  When the state collection execution unit 111 is activated under the control of the collection state control unit 113 (S209), the state collection execution unit 111 starts acquiring the latest information from the device A (S210, S306).

  On the other hand, at the user terminal 2-2, simultaneously with the information acquisition request at the user terminal 2-1, the user presses the collection button (S205), and an information acquisition request signal is given to the monitoring server 1A (S206).

  In the monitoring server 1A, the collection state control unit 113 checks the current collection state data of the collection state holding unit 112 (S207, S302 in FIG. 4).

  At this time, information collection data for apparatus A is recorded. This means that the state collection execution unit 111 for the device A is being executed in response to a request from the user terminal 2-1.

Therefore, the collection state control unit 113 does not activate the state collection execution unit 111 for the information acquisition request from the user terminal 2-2, and collects the state acquisition request information for the device A received from the user terminal 2-2. Store as data (S208, S305)
Then, the activated state collection execution unit 111 completes the acquisition of the latest information on the operation state and the failure state from the device A.

  The collection state control unit 113 confirms the collection state data for the device A recorded in the collection state holding unit 112. In this example, it is confirmed that the user terminal 2-1 and the user terminal 2-2 are recorded in the request source as the collection state data for the device A.

  Therefore, the collection state control unit 113 transmits the collection information acquired from the device A to the user terminals 2-1 and 2-2 (S211 and S307).

  Then, the user terminals 2-1 and 2-2 update the Web screen to display the latest information of the device A (S212).

(A-3) Effects of the First Embodiment As described above, according to the first embodiment, the latest status acquisition for the monitored device is performed for the latest information acquisition for the same monitored device received simultaneously. This process is performed only once.

  For this reason, the load concerning the processing of the monitoring server and the monitored device does not increase. Also, the response to each request is not delayed.

(B) Second Embodiment Next, a second embodiment of the information collection apparatus, information collection program, and monitoring system of the present invention will be described with reference to the drawings.

  In the second embodiment, in addition to the configuration of the first embodiment, an embodiment in the case where the monitoring server periodically collects the latest information of the monitored device is illustrated.

(B-1) Configuration of Second Embodiment FIG. 5 is a configuration diagram showing the overall configuration of the monitoring system and the internal configuration of each component according to the second embodiment.

  5, the monitoring system 10 of the second embodiment is similar to the first embodiment in that the monitoring server 1B, the plurality of user terminals 2 (2-1 and 2-2), and the monitored device 3 (3- 1 and 3-2).

The second embodiment is different from the first embodiment in the state collection function of the monitoring server 1B. Therefore, the following description will be made in detail with a focus on the state collection function of the monitoring server 1B.

  As shown in FIG. 5, the monitoring server 1B includes at least a state collection unit 11B and a communication unit 12.

  The state collection unit 11B includes at least a state collection execution unit 111, a collection state holding unit 112, a collection state control unit 113, and a regular collection execution unit 114.

  The periodic collection execution unit 114 periodically collects information under the control of the collection state control unit 113. The regular collection execution unit 114 corresponds to, for example, an information collection thread.

  Here, when there are a plurality of monitored devices 3 to be periodically collected, the periodic collection execution unit 114 starts at a cycle determined for each monitored device 3. The activation cycle is not particularly limited, and may be different for each monitored device 3.

  In addition to the processing described in the first embodiment, the collection state holding unit 112 holds state collection data of the periodic collection execution unit 114 when the periodic collection execution unit 114 is activated.

  In addition to the control described in the first embodiment, the collection state control unit 113 periodically starts the periodic collection execution unit 114.

  Further, the collection state control unit 113 confirms the collection state data of the collection state holding unit 112 when an information acquisition request is received from the user terminal 2 or before the periodic collection execution unit 114 is activated.

  If the information collection for the same monitored device 3 is being executed, the collection state control unit 113 does not start the new state collection execution unit 111 or the periodic collection execution unit 114, and the request information Recorded in the collection state holding unit 112.

  On the other hand, when information collection for the same monitored device 3 is not being executed, the collection state control unit 113 activates a new state collection execution unit 111 or a regular collection execution unit 114. Further, the collection state control unit 113 records the information collection data of the new state collection execution unit 111 or the regular collection execution unit 114 in the collection state holding unit 112.

  As a result, even when the latest information is periodically collected from the monitored device 3 and when the latest information is collected in response to a request from the user terminal 2, new information collection cannot be executed. The result of information collection being executed can be returned as the latest information.

(B-2) Operation of Second Embodiment Next, the operation of the information collecting method in the monitoring system 10 of the second embodiment will be described with reference to the drawings.

  FIG. 6 is an explanatory diagram illustrating a flow of the information collection method according to the second embodiment. FIG. 7 is a flowchart illustrating information collection processing in the monitoring server 1B according to the second embodiment.

  Below, the operation | movement when the regular collection with respect to the to-be-monitored apparatus 3-1 and the information acquisition request from the user terminal 2-2 exist in the same period is illustrated. For convenience of explanation, the monitored device 3-1 is also referred to as device A, and the monitored device 3-2 is also referred to as device B.

First, in the monitoring server 1B, when the regular collection timing for the device A is reached (S501), the collection state control unit 113 checks the collection state data of the collection state holding unit 112 (S302, S401).

At this time, there is no information acquisition request from the user terminal 2, and no corresponding collection state data is recorded in the collection state holding unit 112. Therefore, the collection state control unit 113 activates the regular collection execution unit 114 (S303), and records the collection state data of the regular collection execution unit 114 in the collection state holding unit 112 (S304, S402).

  When the regular collection execution unit 114 is activated under the control of the collection state control unit 113 (S403), the regular collection execution unit 114 collects the latest information from the device A (S404).

At the same time as the periodic collection for the device A, the user also presses the collection button at the user terminal 2-2 (S405), and an information acquisition request signal is given to the monitoring server 1B (S406, S501).

  In the monitoring server 1B, the collection state control unit 113 checks the current collection state data of the collection state holding unit 112 (S407, S302).

At this time, the periodic collection execution unit 114 is executing information collection for the device A. Therefore, the collection state control unit 113 does not activate the state collection execution unit 111 in response to the information acquisition request from the user terminal 2-2.

  The collection state control unit 113 stores state collection data for the device A from the user terminal 2-2 (S408, S305).

  Then, the activated periodic collection execution unit 114 that has been activated completes the acquisition of the latest information on the operation state and the failure state from the device A.

  The collection state control unit 113 confirms that the user terminal 2-2 makes an information acquisition request for the device A based on the collection state data of the collection state holding unit 112, and sends the acquired information to the user terminal 2- 2 (S409, S307).

  Then, the user terminal 2-2 updates the Web screen and displays the latest information of the device A (S410).

  Contrary to the above description of the operation, when the periodic process is performed while the request for acquiring the latest state from the user terminal is being executed, the acquisition of the latest state to the monitored device 3 is performed once as in the above case. Only do.

(B-3) Effect of Second Embodiment As described above, according to the second embodiment, in addition to the effect of the first embodiment, the monitoring server periodically updates the latest information from the monitored device. Even in the case of collection, the latest information acquisition process for the monitored apparatus can be performed only once.

  As a result, the load related to the processing of the monitoring server and the monitored device does not increase. Moreover, the response to the request from the terminal is not delayed.

(C) Other Embodiments In the above-described embodiments, when two user terminals simultaneously make an information acquisition request for the same monitored device, or for the same monitored device from one user terminal.
