Abstract

In a device monitoring system for a communication network, an SNMP monitor acquires state information of devices to be monitored from a group under monitoring, and monitors the states of the devices to be monitored. A command monitor uses a monitor command to acquire the state information of the devices to be monitored. A monitor manager checks monitoring conditions of the devices to be monitored by the SNMP monitor, and sets, if there is a device to be monitored from which state information has failed to obtain, the device as a new target for monitoring and causes the command monitor to transmit a monitor command. The monitoring result is updated by the state information acquired by the command, thereby improving the reliability of failure monitoring.

First claim

1 . A monitoring system comprising:
a first monitor which acquires state information from each of a plurality of devices to be monitored based on a first monitoring scheme, and monitors states of the plurality of devices to be monitored; a second monitor which is responsive to an instruction based on a second monitoring scheme to acquire state information from any of the plurality of devices to be monitored, and monitors a state of the device to be monitored; and a monitor manager which manages monitoring results for the plurality of devices to be monitored, wherein said monitor manager acquires the state information by said first monitor to manage the state information, and, when the state information has failed to acquire from one of the plurality of devices to be monitored, said manager provides said second monitor with the instruction to set the one device as a new target for monitoring for acquiring the state information, and uses the state information acquired by said second monitor in response to the instruction to manage the monitoring result.

2 . The monitoring system in accordance with claim 1 , wherein
said monitor manager includes a monitor memory which stores execution states of a monitoring by said first monitor and the monitoring results for the plurality of devices to be monitored respectively in association with the plurality of devices to be monitored, and said monitor manager sets the device to be monitored, from which the state information has failed to acquire in the monitoring by said first monitor, as the new target for monitoring, and provides the instruction to said second monitor.

3 . The monitoring system in accordance with claim 2 , wherein said monitor manager includes:
a checker which references said monitor memory to set a device of which the execution state indicates uncompleted among the plurality of devices to be monitored as the target for monitoring, and provides the instruction to said first monitor; an instruction section which sets the device to be monitored, from which the state information has failed to acquire, as the new target for monitoring, and provides the instruction to said second monitor; an acquisition section which acquires as the monitoring result the state information which said second monitor acquires from the device to be monitored in response to the instruction; and an updater which uses the state information acquired by either said first monitor or said second monitor to update the monitoring result in said monitor memory.

4 . The monitoring system in accordance with claim 1 , wherein the first monitoring scheme is SNMP (Simple Network Management Protocol), and said first monitor includes:
an object manager which manages the device state information acquired according to definition regarding state monitoring for the plurality of devices to be monitored; and a controller which determines the monitoring result from comparing the device state information acquired with a threshold set in accordance with a type of the device state information.

5 . The monitoring system in accordance with claim 1 , wherein the second monitoring scheme is a command method which references the state of each of the plurality of devices to be monitored.

6 . The monitoring system in accordance with claim 1 , further comprising a plurality of second monitors, wherein the second monitoring scheme is a command method which references the state of each of the plurality of devices to be monitored, and plural types of state information are acquired.

7 . A monitoring apparatus comprising:
a first monitor which acquires state information from each of a plurality of devices to be monitored based on a first monitoring scheme, and monitors states of the plurality of devices to be monitored; a second monitor which is responsive to an instruction based on a second monitoring scheme to acquire state information from any of the plurality of devices to be monitored, and monitors a state of the device to be monitored; and a monitor manager which manages monitoring results for the plurality of devices to be monitored, wherein said monitor manager acquires the state information by said first monitor to manage the state information, and, when the state information has failed to acquire from one of the plurality of devices to be monitored, said manager provides said second monitor with the instruction to set the one device as a new target for monitoring for acquiring the state information, and uses the state information acquired by said second monitor in response to the instruction to manage the monitoring result.

8 . The monitoring apparatus in accordance with claim 7 , wherein
said monitor manager includes a monitor memory which stores execution states of a monitoring by said first monitor and the monitoring results for the plurality of devices to be monitored in association with the plurality of devices to be monitored, and said monitor manager sets the device to be monitored, from which the state information has failed to acquire in the monitoring by said first monitor, as the new target for monitoring, and provides the instruction to said second monitor.

9 . The monitoring apparatus in accordance with claim 8 , wherein said monitor manager includes:
a checker which references said monitor memory to set a device of which the execution state indicates uncompleted among the plurality of devices to be monitored as the target for monitoring, and provides the instruction to said first monitor; an instruction section which sets the device to be monitored, from which the state information has failed to acquire, as the new target for monitoring, and provides the instruction to said second monitor; an acquisition section which acquires as the monitoring result the state information which said second monitor acquires from the device to be monitored in response to the instruction; and an updater which uses the state information acquired by either said first monitor or said second monitor to update the monitoring result in said monitor memory.

10 . The monitoring apparatus in accordance with claim 7 , wherein the first monitoring scheme is SNMP (Simple Network Management Protocol), and said first monitor includes:
an object manager which manages the device state information acquired according to definition regarding state monitoring for the plurality of devices to be monitored; and a controller which determines the monitoring result from comparing the device state information acquired with a threshold set in accordance with the type of the device state information.

11 . The monitoring apparatus in accordance with claim 7 , wherein the second monitor scheme is a command method which references the state of each of the plurality of devices to be monitored.

12 . The monitoring apparatus in accordance with claim 7 , further comprising a plurality of second monitors, wherein the second monitoring scheme is a command method which references the state of each of the plurality of devices to be monitored, and plural types of state information are acquired.

13 . A monitoring method for monitoring based on state information from each of a plurality of device to be monitored, wherein a monitoring apparatus is used which comprises:
a first monitor which acquires state information from each of the plurality of devices to be monitored based on a first monitoring scheme, and monitors states of the plurality of devices to be monitored; a second monitor which is responsive to an instruction based on a second monitoring scheme to acquire state information from any of the plurality of devices to be monitored in, and monitors a state of the
