OpenManage Power Center Temperature Monitoring OMPC


Dell OpenManage Power Center enables monitoring of the current or historical temperature of the data centers in Power Center. This can help you understand the temperature status and identify hot spots in the data center.

NOTE: Before downloading OPMC you have to register first.



You can monitor the temperature status at different device/group levels. You can configure the temperature monitoring settings to meet your monitoring needs, and you can print the temperature status graph.

Temperature Monitoring Level
Power Center provides temperature monitoring at the following levels:

  • Device level — You can monitor temperature-related metrics for devices.
  • Physical group level — You can monitor temperature-related metrics at the physical group level (data center, room, aisle, chassis modular).
  • Logical group level — You can monitor temperature-related metrics at the logical group level.

Temperature Monitoring Configuration
You can configure temperature monitoring settings in Power Center, including:

  • Thresholds (Inlet temperature range for events)
  • Device and group range (Monitor all or not)
  • Sampling interval (1, 3, or 6 minutes)
  • Default units (Celsius or Fahrenheit)

Temperature Thresholds
It is useful to monitor thresholds when you want to be notified when the temperature of the group/device exceeds the thresholds. Once the temperature value exceeds a critical or warning threshold, an alert is sent.
To configure thresholds:

  1. Click Devices in the left navigation pane, then select either the Grouped Devices or the Unassigned Devices tabs.
  2. Select the group or device for which you want to set a temperature alert threshold.
  3. In the details section of the screen, click Edit Temperature Alert Thresholds.
    The Edit Temperature Alert Thresholds screen opens. The device or device group name is displayed after the screen title.
  4. Enter values for the following:
    • Average Inlet Thermal Greater Than Critical Level—When the temperature is greater than the setting, the critical-level event "Average Inlet Temperature" alert is sent.
    • Average Inlet Thermal Less Than Critical Level—When the temperature is less than the setting, the critical-level event "Average Inlet Temperature" alert is sent.
    • Average Inlet Thermal Greater Than Critical Level—When the temperature is greater than the setting, the warning-level event "Average Inlet Temperature" alert is sent.
    • Average Inlet Thermal Less Than Warning Level—When the temperature is less than the setting, the warning-level event "Average Inlet Temperature" alert is sent.
  5. Click Finish to apply the new alert thresholds, or click Cancel to discard your changes..
    After you have configured the thresholds, you will see four lines with different colors indicating the thresholds in the Temperature Details tab.

Viewing Temperature Details
Click Devices in the left navigation pane, then select the Grouped Devices or Unassigned Devices tab. Click the icon for the group or device, then refer to the lower detail portion of the screen.
Click View History under the Present Power heading to access the Temperature Details graph. By default, the Temperature Details graph displays the temperature details for the previous hour.
You can also view the following details:

Temperature Details for the Current Time Window
You can view temperature details for the current time window by clicking a time window tab.

Temperature Details for a Different Time Window
Click the arrows < > to view the details for the previous/next sampling time, or click the double arrows << >> to view the details for the previous/next page of results for the current time window. You can click Average, Maximum, or Minimum to display the selected value.

  • Average: The average value from the previous time point to the current time point.
  • Maximum: The maximum value from the previous time point to the current time point.
  • Minimum: The minimum value from the previous time point to the current time point.

For example, you view temperature details in the 1H (1 hour) window and the maximum value at 15:00 shows 40°C and the time interval is 6 minutes. This value would represent that the maximum temperature from 14:54 to 15:00 is 40°C.

Chassis Details
The Chassis Details table appears when you select a chassis on the Devices screen. Chassis Details lists all blade servers within the chassis and their temperature details in a table, including:

  • Device: Device name.
  • Average: The average value of the latest sampling interval.
  • Maximum: The maximum value of the latest sampling interval.
  • Minimum: The minimum value of the latest sampling interval.

NOTE: You can set the time interval (the period from a time point to the next time point) in the Settings > General page. For information on configuring the interval, see Monitoring Settings.
NOTE: The Average, Maximum, or Minimum field displays NA if no data is available—for example when the blade server is an Unsupported device.


Viewing A Temperature History Graph
Dell OpenManage Power Center provides a visual representation of the temperature history of your system devices.

  1. Click Devices in the left navigation pane.
  2. On the Grouped Devices tab, select a device entity.
  3. In the details section of the screen under Present Temperature, click View History.
    A graphical representation of the selected device entity's temperature history appears.
  4. Select the time period and attributes displayed:< >To select the time period represented in the graph, click the buttons along the top of the graph.To add or delete attributes, select from among the options listed; click the option to toggle its addition or removal from the graph:MinimumMaximumAverageWarning MaxCritical MaxWarning MinCritical MinTo move along the data stream over time, click the navigation arrows below the graph.

Monitoring the Temperature of the Chassis/Blade Server
You can monitor the inlet temperature at the blade server level.
You can also monitor the inlet temperature at the chassis level, including average, maximum, and minimum details.

Monitoring the Temperature of Devices/Groups
Power Center supports temperature monitoring of the inlet temperature span for devices and groups. The inlet temperature span is the average inlet temperature differential between the maximum and minimum temperature reading for a device in a group (Celsius or Fahrenheit). You can calculate this value according to the maximum and minimum temperature from the Temperature Details graph.
