Node monitoring apparatus, node monitoring method, and computer readable medium

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.
