• Power/Temperature sampling interval — Every 30 minutes, for example, 08:00, 08:30, 09:00, and so on.
Conguring the power and temperature sampling intervals
1 On the Settings screen, click the Monitoring tab. Select the Monitoring all devices and groups check box to enable the power and
thermal monitoring of all devices and groups.
2 Enter values in the Power Sampling Interval and Temperature Sampling Interval text boxes.
The default power and temperature sampling interval is one minute.
3 Click Save to apply the settings, or click Reset to revert to the previously saved settings.
Conguring the power and temperature monitoring units
1 Under Monitoring > Power Units settings, select the unit of measurement in which the power consumption must be displayed.
The available options are:
• Watts
• BTU/hr
2 Under Temperature Units, select one of the following options in which the temperature monitoring must be displayed.
The available options are:
• Celsius
• Fahrenheit
3 Click Save to apply the settings, or click Reset to revert to the previously saved settings.
Conguring energy consumption cost settings
1 In the left pane, click Settings > Monitoring.
2 In the Energy Consumption Cost section, enter values in the Flat Rate and Cooling Multiplier text boxes.
Flat rate is the cost of power used per kWh in the specied currency.
Cooling Multiplier is used to estimate the energy needed to cool the device or device group.
3 From the Currency drop-down list, select the currency in which the energy consumption cost must be displayed.
4 Click Save to apply your settings, or click Reset to revert to the previously saved settings.
NOTE
: Changes to the Cooling Multiplier take eect immediately. But, changes to the Flat Rate take eect at the
beginning of the next hour.
Database policy settings
Database policy settings are used to congure the database maintenance policy.
OpenManage Power Center stores monitoring data for your data center in a database le, using compressed power/temperature data to
optimize for higher query performance and smallest database size. It stores both power/temperature compressed data and non-
compressed data in the database. Data compression helps improve data query eciency by aggregating and saving monitoring data using a
bigger granularity (hourly or daily), but not the original granularity decided by the Sampling Interval.
By default, OpenManage Power Center keeps compressed power/temperature data and event data up to 365 days and non-compressed
power/temperature data up to 14 days. You can congure the duration for which OpenMange Power Center retains compressed and non-
compressed data using the Data compression and Purge data (older than) elds. Data that exceeds its duration or is older than the purge
date is deleted. This improves the eciency of the data query. You can automatically purge data by using the Schedule Purge eld, or you
can trigger it manually to start purging data immediately (see “Purge Database Now,” below).
