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 AlertViewer 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.
„ Types of reported faults
The table below lists the typical faults reported by NEC ESMPRO Agent.
Component Reported information
CPU
•
CPU load is over the threshold
•
CPU degrading, etc.
Memory ECC 1-bit error detection, etc.
Power supply
•
Voltage lowering
•
Power failure, etc.
Temperature Temperature increase in chassis, etc.
Fan Fan failure (decrease in the number of revolutions), etc.
Storage File system usage rate, etc.
LAN
•
Line fault threshold over
•
Send retry or send abort threshold over, etc.
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 the CPU usage rate
and the empty capacity in a file system, etc. 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 the CPU
usage rate.
