Detection Of Server Fault; Prevention Of Server Fault - NEC Express 5800 User Manual

Detection of Server Fault

NEC ESMPRO Manager and NEC ESMPRO Agent detect errors causing faults to occur at an early
stage and notify Administrators of fault information real-time.
Early detection of error
If a fault occurs, NEC ESMPRO Agent detects the fault and reports the occurrence of the
fault to NEC ESMPRO Manager (alert report). NEC ESMPRO Manager displays the
received alert in the alert viewer and also changes the status colors of the server and server
component in which the fault occurs. This allows you to identify the fault at a glance.
Further, checking the content of the fault and the countermeasures, you can take
appropriate action for the fault as soon as possible.

Prevention of Server Fault

NEC ESMPRO Agent includes the preventive maintenance function forecasting the occurrence of a
fault as countermeasures for preventing faults from occurring.
NEC ESMPRO Manager and NEC ESMPRO Agent can set the threshold for each source in the
server. If the value of a source exceeds the threshold, NEC ESMPRO Agent reports the alert to NEC
ESMPRO Manager.
The preventive maintenance function can be set for a variety of monitoring items including cabinet
temperature, and CPU usage rate.
Reported information
•
CPU load is over the threshold
•
CPU degrading, etc.
ECC 1-bit error detection, etc.
•
Voltage lowering
•
Power failure, etc.
Temperature increase in cabinet, etc.
Fan failure (decrease in the number of revolutions), etc.
File system usage rate, etc.
•
Line fault threshold over
•
Send retry or send abort threshold over, etc.
