Abstract

There is provided a node monitoring apparatus including: a node identification unit that identifies a function of a node present in a network; a parameter setting unit that sets a parameter for monitoring processing on the node in accordance with the function identified by the function identification unit; and a node monitoring unit that performs the monitoring processing on each of the nodes based on the parameter set by the parameter setting unit.

Claims

1. A node monitoring apparatus comprising:

a function identifier configured to identify a function of at least one node out of a plurality of nodes present in a network based on a working operating system and a service at work of the node;

a relationship identifier configured to identify a relationship of dependence of each of the nodes on the other nodes, the relationship of dependence including at least one of a history of communication between a node and any other node, a frequency of communications between nodes, and an importance level of a task shared among at least two nodes;

a parameter-setter configured to set a parameter for monitoring processing on the node in accordance with the function identified by the function identifier and the dependence relationship identified by the relationship identifier; and

a node monitor configured to perform the monitoring processing on each of the nodes based on the parameter set by the parameter setter.

2. The node monitoring apparatus according to claim 1, wherein the parameter setter sets the parameter for each node in accordance with its use frequency.

3. The node monitoring apparatus according to claim 1, wherein the function identifier identifies the function of each node by using a plurality of types of protocols.

4. The node monitoring apparatus of claim 1, further comprising an importance level storage unit configured to store importance levels associated with a plurality of days of the week and times of day for each node, and wherein the parameter-setter is further configured to set a monitoring interval based on the stored importance levels.

5. A method for monitoring nodes comprising the steps of:

identifying a function of at least one node out of a plurality of nodes present in a network with a monitoring apparatus communicably connected to the nodes within the network, wherein the function is identified based on a working operating system and a service at work of the node;

identifying a relationship of dependence of each of the nodes on the other nodes with the monitoring apparatus, the relationship of dependence including at least one of a history of communication between a node and any other node, a frequency of communications between nodes, and an importance level of a task shared among at least two nodes;

setting a parameter for monitoring processing on the node in accordance with the identified function of the node and the identified dependence relationship; and

performing the monitoring processing on the node based on the set parameter with the monitoring apparatus.

6. The method of monitoring nodes of claim 5, further comprising storing an importance levels associated with a plurality of days of the week and times of day for each node, and wherein setting the parameter further includes setting a monitoring interval based on the stored importance levels.

7. A non-transitory computer-readable medium storing thereon a computer program used in a computer, the computer program causing the computer to perform the steps of:

identifying a function of at least one node out of a plurality of nodes present in a network based on a working operating system and a service at work of the node;

identifying a relationship of dependence of each of the nodes on the other nodes, the relationship of dependence including at least one of a history of communication between a node and any other node, a frequency of communications between nodes, and an importance level of a task shared among at least two nodes;

setting a parameter for monitoring processing on the node in accordance with the identified function of the node and the identified dependence relationship; and

performing the monitoring processing on the node based on the set parameter.

8. The non-transitory computer-readable medium claim 7, further comprising storing an importance level associated with a plurality of days of the week and times of day for each node, and wherein setting the parameter further includes setting a monitoring interval based on the stored importance levels.
