Abstract

There is provided a monitoring apparatus including a monitoring unit that monitors an operating situation of nodes over a network based on a predetermined monitoring parameter, a memory that records the operating situation monitored by the monitoring unit, and a changing unit that changes the monitoring parameters based on a past operating situation recorded by the memory.

Claims

1. A monitoring apparatus comprising:

a monitor configured to monitor an operating situation of nodes over a network based on at least one predetermined monitoring parameter, wherein the monitor utilizes a plurality of network protocols to monitor the operating situation of the nodes, wherein the plurality of network protocols usage is monitored and wherein the at least one predetermined monitoring parameter includes at least a monitoring time period comprising a plurality of time periods during which utilization of the protocols is monitored, timeout duration for monitoring call comprising a plurality of waiting times during which a response from the monitor is established, a monitoring call retry frequency when a timeout occurs for monitoring call, and a predetermined protocol monitoring order;

a monitoring interval, wherein the monitoring interval is the interval when a monitoring call is sent out;

a memory configured to record the operating situation monitored by the monitor; and

a changer configured to adjust the at least one predetermined monitoring parameter based on a past operating situation recorded by the memory;

wherein the changer proposes a user to exclude a time period from the monitoring time period for which all the network protocols were not repeatedly used on nodes for predetermined times in the past based on the operating situation recorded by the memory; and

wherein the changer widens the monitoring interval between monitored time periods for which a protocol was always being utilized in a past predetermined monitored period of time.
