5-32 Installing and Using Utilities
IMPORTANT:
Ensure to restart the machine after checking/unchecking the option. If the machine is not restarted,
the correct load factor cannot be acquired with the Performance Monitor.
(Countermeasure)
If the CPU load factor acquired by the "verification procedure" above greatly differs when the
option of the SQL Server is on and off, it is believed that the CPU load factor increases when the
option is set to on.
The above phenomenon occurs because the amount of performance data collected from the OS
increases when this SQL Server option is set to on; thereby, the service to collect the performance
data from the OS requires time to analyze the performance data.
If you do not need to monitor the performance data of SQL Server, set the SQL Server option to off
in order to prevent the CPU load from increasing due to the collection of unnecessary performance
data.
Event log which warn CPU load monitoring is registered
If NEC ESMPRO Agent cannot acquire performance information from the OS due to a temporary
resource shortage or high load ratio on the system, it will record the following event log. However,
there is no real problem on operation. (In the description, Y and X represent alphanumeric
characters.)
Source: ESMCpuPerf
Type: Information
Event ID: 9005
Description: Cannot get system performance information now (YYYY Code=xxxx).
If NEC ESMPRO Agent cannot get information, it will treat the load ratio as 0%.
Therefore, if NEC ESMPRO Agent cannot get information continuously, the CPU load ratio may
appear lower than the actual value.
Monitoring the failures of the tape device is desired
NEC ESMPRO Agent does not monitor the failures of the tape device. If you want to conduct
monitoring, use backup software or tape monitoring application. Using the event monitoring
function of NEC ESMPRO Agent allows you to monitor the event log of backup software or
applications.
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.
