Viewing peak power distribution graph
OMPC allows you to view the details about the distribution of peak power for the servers.
1. In the left pane, click Analysis → Server Characteristics.
2. In the task menu, click Peak Power.
The Peak Power Distribution — <Server> graph is displayed.
3. Set the power range distribution value by typing the value in Set Y-axis Power Range Granularity text
box and click Apply.
The graph with the minimum and the maximum power distribution of the server models is displayed.
Viewing active idle power distribution graph
OMPC allows you to view the details about the distribution of idle power that is the lowest power
observed for a specific time duration.
1. In the left pane, click Analysis → Server Characteristics.
2. In the task menu, click Active Idle Power.
The Active Idle Power — <Server> graph is displayed.
3. Set the distribution range value by typing the value in Set Y-axis Power Range Granularity text box
and click
Apply.

displayed.
Exporting server power report
OMPC allows you to export the server power report to a local drive on your system.
1. In the left pane, click Analysis → Server Characteristics.
2. In the task menu, click Export All.
The report downloads to your local system in *.CSV format. The filename includes the date and time.
For example, ServerPowerCharacteristics-20150513–124005.csv
Underutilized servers
OMPC helps you in identifying the servers that are not utilized efficiently. The observed data is important
in understanding the overall utilization of servers in a data center and helps in distributing the workload
efficiently.
The server utilization in a data center is calculated using the formula,
• Maximum value of CUPS indices for CPU, Memory bandwidth and I/O bandwidth,
if available
or,
• (Current Power – Idle Power)/(Power Capacity – Idle Power)
where,
• Current power is the power used by the server
