Setting performance management monitoring parameters
Servers are monitored based on the performance monitoring parameters. The monitoring status
and the number of samples must be configured in the Performance Management for servers to be
monitored.
Insight Control performance management monitoring operates in four modes:
• Monitor - This mode enables server status information that HP SIM and HP Insight Control
performance management display. You can view the analysis information using the Online
Analysis tool.
• Monitor Alert - This mode, in addition to the capabilities enabled with Monitor, sends alerts
to HP SIM when the status of a server changes.
• Monitor, Log, Alert - This mode, in addition to the capabilities enabled with Monitor Alert,
stores detailed performance information in the performance management database for later
reporting using the Offline Analysis tool.
• Monitor Log - This mode enables monitoring of servers and stores the performance information
in the performance management database for a playback later.
Number of samples
The Number of samples setting lets you adjust of performance management analysis to account
for highly variable or stable system performance. A higher number of samples results in smaller
average changes in performance; it generates fewer performance bottleneck indications for a
server whose performance changes significantly. Fewer samples can be used for servers with more
stable performance or when the sampling rate is higher.
Sample rate
The default sample rate is 300 seconds.
After you start monitoring a server, the sample rate appears on the Monitoring Administration
page and retrieves data from agents for the monitored server using the sample rate.
NOTE: Sample rate is populated automatically.
