CPU Load Monitoring

F u n c t i o n s

When NEC ESMPRO Agent detects a high-loaded CPU, it will issue a message to syslog and will report the

alert to NEC ESMPRO Manager. You can check which CPU has unusual usage when you refer to NEC

ESMPRO Manager. Since the function monitors load statuses either by individual CPUs or CPU total, you can

monitor a server as one package regardless of the individual CPUs.

CPU load monitoring is not performed at default settings. If you need to monitor CPU load, change the

settings to perform monitoring. You do not have to change threshold values of CPU load rates. Although you

may specify any values, the threshold values near the current values could cause the agent to issue alerts

frequently. When you change CPU load values, be careful not to cause alerts to be issued frequently due to

the setting of the values.

Default values are as follows.

Sample Interval(s): 10

Utilization Rate: Load for 1 min

It acquire the utilization at the point in time every monitoring every a certain ten seconds and compare the

mean [6 (counts) = 60 (seconds of utilization) / 10 (seconds of interval)] targeted for monitoring of one minute

with the threshold as "current utilization". It perform the comparison between "current utilization" and threshold

every the monitoring that it set every a certain ten seconds and report it to a state (normal / warning /

abnormality) when there was a change. When it change the monitoring object from 1 "Load for min" to 5 "Load

for min", it do the mean [30 (counts) = 300 (seconds of utilization) / 10 (seconds of interval)] targeted for

monitoring of one minute with "current utilization" and compare it with the threshold.

S e t t i n g s

From [CPU Load] screen, you can set the following information.

To display [CPU Load] screen, select "CPU" on Control Panel (ESMagntconf).
