File system monitoring cannot be inherited on the system using
NECEXPRESSCLUSTER
When using NEC ESMPRO Agent in the cluster environment configured by NEC
EXPRESSCLUSTER, there is a following limitation:
If a failover occurs, the settings of the threshold for the empty space monitoring function and the
enable/disable of monitoring of the operating sever are not inherited to the standby server. Make
sure to reset the threshold and the enable/disable of monitoring on the standby server.
CPU Load Ratio of SNMP Service (snmp.exe)
While monitoring the server from NEC ESMPRO Manager, the CPU load ratio of SNMP Service
on the NEC ESMPRO Agent side may increase at every monitoring interval (default: 1 minute).
NEC ESMPRO Manager and NEC ESMPRO Agent exchange information through SNMP Service.
If the server status monitoring by NEC ESMPRO Manager is on (default: ON), NEC ESMPRO
Manager regularly issues a request to NEC ESMPRO Agent to get the current status of the server. In
response, NEC ESMPRO Agent checks the status of the server. As a result, the CPU load ratio of
SNMP Service increases temporarily.
If you have trouble of terminating a movie player application, turn off the server status monitoring
by NEC ESMPRO Manager or extend the monitoring interval.
Hang of SNMP Service
SNMP Service has a module called "SNMP Extended Agent." This module may be registered when
you install some software that uses SNMP Service.
If you start SNMP Service, SNMP Extended Agent is also loaded at the initialization. However, if
the initialization is not completed within a specified period, SNMP Service will hang.
It may take time to complete the initialization due to temporary high load on the system. In this case,
wait for the system load become low enough before restarting SNMP Service.
Display for Temperature/Power Voltage/Fan Sensors
On some models, temperature/power voltage/fan sensors do not have information on the status,
current values, revolutions, thresholds, etc. Note that the following may be displayed when
referring to the applicable sensor on NEC ESMPRO Manager.
• On the DataViewer, the status is shown as "Unknown" (grayed out).
• On the DataViewer, the current value and revolutions are not displayed, or they are shown as
"Unknown."
Even if the above are displayed, there is no problem as the monitoring is being performed.
