128 Performance and Power Monitoring
Power Monitoring
The power monitoring feature helps you to collect, store, and display the
instantaneous values of power (watts) consumed, amperes drawn by each
power supply, and the total energy consumed by a device.
NOTE: The power monitoring feature requires that the Dell OpenManage Server
Administrator version 5.3 or later be installed on the managed systems.
You can choose the appropriate power monitoring counters from the
performance and power manager task wizard and select the frequency in
which the data is collected. The collected data is available on the
Performance and Power tab associated with each device, or the Execution
Results tab associated with each Performance and Power Monitoring task.
The maximum value observed for a given system (Watts/Amps) is also
collected during each polling cycle. This value is compared with the existing
peak value in the IT Assistant database, and if the values are different,
the database value is replaced with the values in the current polling cycle.
The new value is displayed on the Group Summary and Maximum Values
tab in the Performance and Power Monitoring screen.
NOTE: IT Assistant polls the managed systems at a frequency that you determine.
If you select a polling frequency that is too low, it is possible that the variations in
the power consumption are not captured adequately, and this may result in
inaccurate instantaneous power consumption graphs.
Performance and Power Monitoring in Tom’s

Tom wants to use this feature to monitor how

systems,
on his network are being used.
His main considerations for using this feature are:
• Are the systems on my network under- or over-utilized?
• Do I need to move my hardware (for example, CPU) or applications to
another system?
• How are my systems performing during peak and non-peak hours?
• What is the energy consumption and the peak power values in my systems?
• Would I need to balance the load among my systems?
