Abstract

An information processing system includes a plurality of monitoring target devices and a plurality of monitoring devices. A monitor device monitors one or more monitoring target devices allocated to the each monitoring device. The monitor device acquires monitor information from one or more monitoring target devices allocated to the monitoring device, and stores the acquired monitor information in a memory provided for the monitor device. When transmitting the monitor information stored in the memory to another monitoring device, the monitor device controls control transmission of the monitor information so that first monitor information that is the monitor information having a high priority and identified based on a type of the monitor information is transmitted in priority to second monitor information that is the monitor information other than the first monitor information.

Claims

1. An information processing system comprising:

a plurality of monitoring target devices; and

a plurality of monitoring devices each configured to monitor one or more monitoring target devices allocated to the each monitoring device, wherein

a first monitoring device among the plurality of monitoring devices is configured to;

acquire monitor information from the one or more monitoring target devices allocated to the first monitoring device;

store the acquired monitor information in a first memory provided for the first monitoring device; and

when transmitting the monitor information stored in the first memory to a second monitoring device among the plurality of monitoring devices, control transmission of the monitor information so that first monitor information that is the monitor information having a high priority and identified based on a type of the monitor information is transmitted in priority to second monitor information that is the monitor information other than the first monitor information.

2. The information processing system of claim 1, wherein

the second monitoring device is configured to:

store the transmitted monitor information in a second memory of the second monitoring device, and

perform synchronization of the monitor information so that the monitor information stored in the second memory matches with the monitor information stored in the first memory of the first monitoring device that has transmitted the monitor information.

3. The information processing system of claim 1, wherein

the monitor information includes, as the first monitor information, state information indicating state of each of the plurality of monitoring target devices, and event information indicating an event occurring in each of the plurality of monitoring target devices.

4. The information processing system of claim 3, wherein

the event information includes a type of event occurring in each monitoring target device, and

the first monitoring device is configured to:

discriminate, based on the type of event, between first event information transmitted with a first priority and second event information transmitted with a second priority lower than the first priority, and

control transmission of the monitor information so that the first event information is transmitted to the second monitoring device in priority to the second event information.

5. The information processing system of claim 4, wherein

each monitoring device stores, in a memory provided therefor, holding device information that associates an identifier identifying each of the one or more monitoring target devices with an identifier identifying a monitoring device that stores event information of the each monitoring target device;

a third monitoring device having event information of a first monitoring target device determines, based on the holding device information thereof, whether at least two monitoring devices store event information of the first monitoring target device;

when at least two monitoring devices do not store event information of the first monitoring target device, the first monitoring device instructs a fourth monitoring device other than the third monitoring device to acquire event information of the first monitoring target device; and

the third monitoring device already storing event information of the first monitoring target device discriminates between the first and second event information out of the already stored event information of the first monitoring target device, and controls transmission of the monitor information so that the first event information is transmitted to the fourth monitoring device, in priority to the second event information.

6. The information processing system of claim 5, wherein

when a second monitoring target device is newly added to the information processing system, a fifth monitoring device already storing event information of the second monitoring target device discriminates between the first and second event information of the already stored event information of the second monitoring target device, and controls transmission of the monitor information so that the first event information is transmitted to a sixth monitoring device other than the fifth monitoring device, in priority to the second event information.

7. The information processing system of claim 6, wherein

the fifth monitoring device is configured to:

when the second monitoring target device is newly added to the information processing system, store, in a memory provided therefor, the holding device information that further includes an identifier identifying the added second monitoring target device and an identifier identifying each of one or more monitoring devices storing event information of the added second monitoring target device;

store, in the memory thereof, the state information further including state information of the added second monitoring target device; and

control transmission of the monitor information so that the state information of the added second monitoring target device and the holding device information, which includes an identifier of the added second monitoring target device and identifiers of one or more monitoring devices storing event information of the added second monitoring device, are transmitted to the sixth monitoring device.

8. The information processing system of claim 5, wherein

when a second monitoring target device is deleted from the information processing system, a fifth monitoring device having event information of the second monitoring target device:

transmits, to monitoring devices other than the fifth monitoring device, an instruction signal for deleting state information and holding device information of the second monitoring target device; and

transmits, to a sixth monitoring device already storing event information of the second monitoring target device, an instruction signal for deleting the event information of the second monitoring target device.

9. The information processing system of claim 5, wherein

in a case where a third monitoring device is newly added to the information processing system, a fourth monitoring device that is any one of the plurality of monitoring device:

controls transmission of the monitoring information so that state information already stored in a memory provided the fourth monitoring device is transmitted to the third monitoring device,

determines, based on the holding device information, one or more monitoring target devices to be monitored by the second monitoring device, and

controls transmission of the monitor information so that holding device information including identifiers identifying the determined one or more monitoring target devices and an identifier identifying the second monitoring device is transmitted to monitoring devices other than the each monitoring device; and

a fifth monitoring device already storing event information of the second monitoring target device discriminates between the first and second event information out of the event information already stored in the fifth monitoring target device, and controls transmission of the monitor information so that the first event information is transmitted, to the second monitoring device, in priority to the second event information.

10. The information processing system of claim 5, wherein

in a case where a third monitoring device is deleted from the information processing system, a fourth monitoring device already storing event information pertaining to the third monitoring device discriminates between the first and second event information out of the event information pertaining to the third monitoring device, which is stored in the fourth monitoring device, and controls transmission of the monitor information so that the first event information is transmitted, in priority to the second event information, to monitoring devices other than monitoring devices already storing event information pertaining to the third monitoring device.

11. A monitoring device in an information processing system including a plurality of monitoring target devices, and a plurality of monitoring devices each configured to monitor one or more monitoring target devices among the plurality of monitoring target devices, the monitoring device comprising:
