5-20 Installing and Using Utilities

Monitoring with NEC ESMPRO Manager Ver.4.22 or Earlier

NEC ESMPRO Manager Ver.4.23 or later is required for monitoring the server.

If you are using an older version, you must install NEC ESMPRO Manager using the CD-ROM shipped with the server.



ESRAS Utility

ESRAS Utility runs on NEC Express5800 series with NEC ESMPRO Agent installed, and is used to display, print, and initialize logs and export them to a file.

If you attempt to collect ipmi.dat immediately after starting the OS or disconnecting the system, a message “IPMI driver operation error” is displayed. Wait awhile and try collecting ipmi.dat again.



Coexistence with the Oracle products

The installation of the Oracle products may change Startup Type of SNMP Service into “Manual.” If so, change the setting back to “Automatic” and set up correctly according to the description of the Oracle product.



Connection with Hard Disk Drive

The preventive hard disk drive maintenance function may not work properly when a hard disk drive which was used in a system where NEC ESMPRO Agent is installed is connected to other systems. Make sure not to connect such hard disk drives.



Change Settings of File System Monitoring Function

New settings in thresholds of monitoring interval and free space monitoring are not reflected immediately after they are changed. They are reflected at the next monitoring interval of monitoring service.



CPU Load Ratio of SNMP Service (snmpd)

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.
