2. In the Protocols Timeout section, enter the time in seconds for the specified communication protocol (IPMI, SNMP, WS-
MAN, HTTPS, or SSH).
OpenManage Power Center considers the device not reachable if it cannot get any response from the device within the
timeout period.
3. Click Save to apply your settings, Reset to revert to the previously saved settings.
The new settings take effect the next time when Power Center communicates with the device.
Monitoring settings
These settings are used to enable/disable monitoring and set the sampling interval:
● Monitor all devices and groups – Enables or disables monitoring of all devices and groups. By default, the check box is
selected. If you clear the check box, you cannot view the device or group power and temperature details.
○ Power sampling interval – Power Center gets power data according to the sampling interval you set (1, 3, 6, or 10
minutes). You can view power data on the Power Details page. The default is 1 minute.
○ Temperature sampling interval – Power Center gets temperature data according to the sampling interval you set (1, 3,
6, or 10 minutes). You can view temperature data on the Temperature Details page. The default is 1 minute.
● Monitoring Units
○ Power Units — The power consumption of a device or device group is displayed in the unit option you select (Watts or
BTU/hr). By default, the power consumption is displayed in Watts.
○ Temperature Units — The temperature data of a device or device group is displayed in the unit option you select
(Celsius, Farenheit). By default, the temperature data is displayed in Celsius.
● Energy Consumption Cost — The power consumption cost comprises the following components:
○ Flat Rate — It is the cost of power used per kilowatt hour in the specified currency.
○ Cooling Multiplier — It is used to estimate the energy required to cool the device or device group.
○ Currency — Select the currency in which you want to calculate the energy consumption cost from the drop-down list.
Recommended sampling intervals for performance tuning and scaling
It is important to configure appropriate Power and Temperature Sampling Intervals in Power Center, because sampling intervals
impact the system performance and footprint significantly, including network bandwidth consumption, database size, and trend
graph display latency.
The default power and temperature intervals in Power Center are 1 minute. This value is appropriate for small- or medium-sized
environments where the device number is less than 1000; however, when the environment has more managed devices, it is
recommended to adjust the values to 3 or 6 minutes.
NOTE: The device number includes only supported devices. Unsupported devices are not counted.
When are the settings effective?
● Monitor all devices and groups — Immediately
● Power/Temperature sampling interval — Every 30 minutes, for example, 08:00, 08:30, 09:00, and so on.
Configuring 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.
