Users Guide

By default, the General settings screen is displayed.
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?
