Frequently Asked Questions
Why am I not able to view the metrics?
Cause: After removing the required iDRAC or DC License, or the OpenManage Enterprise Advanced Feature license, the
license-dependent features are not available on the User Interface (UI). Therefore, the metric is not available, and the values are
not collected by Power Manager from the next inventory cycle.
Why do I see two entries with the same date in the graph
when the time duration chosen for showing the graph is
changed?
Cause: When viewing the Metrics and Monitoring History graphs for 3 months, 6 months, or 1 year, the data is auto-
converted from the UTC time zone to your current time zone and displayed. Due to the time zone differences, there are two
entries for the same day on the graphs. Therefore, the last entry is for the current day, and the last but one entry is for the
previous day.
Why do I see slight variations in values of power and
temperature in the Alert Thresholds section?
Cause: When the power and temperature values are provided in BTU/Hour and Fahrenheit, they are converted to Watt and
Celsius. When the values are displayed, they are reconverted and rounded off to the next highest numbers. Therefore, the
values are slightly higher when displayed in BTU/Hour and Fahrenheit scale.
Why are there same number of power cap or threshold
violations for all the entries in my report?
Cause: For a in-built or custom report which consists of a violation attribute along with a timestamp attribute, the violation
count that is displayed for all the entries is always for the latest value.
Why do I see blank entries for total energy consumed in
reports or metrics graphs?
Cause: The Total Energy Consumed field has no entry for servers and PowerEdge MX7000 devices due to the following
reasons:
● The energy consumption value is not available until the second metric collection is taken.
● If you change the Data gathering interval to 60 minutes, then for a 60 minutes time period the Energy Consumption
value cannot be calculated. This happens when data is collected for a day with hourly granularity for reports.
● If the power metric in iDRAC is reset during the interval that is chosen, and the latest reading has a lower value than the
oldest reading.
