Device - Performance: CPU Utilization

This device performance report displays CPU utilization percentages collected during the selected time period from the device displayed at the top of the report. You can configure the data collection for this device through Device Properties - Performance Monitors > Configure CPU Utilization.

Report Body

Below the date/time picker is a graph showing the CPU utilization for the selected time period. Each point on the graph corresponds with an entry in the graph data table below.

Split Second Graph - Real-Time CPU Utilization

Under the main report graph is a Split Second Graph that displays real-time utilization data for the CPU.

Note: Split Second Graphs are not available in WhatsUp Gold Standard Edition.

Note: Split Second Graphs are not available in VMware host reports.

Note: When viewing information for devices running Microsoft Windows, information gathered via WMI is displayed in real time. Information gathered by SNMP, however, may reflect a delay of one minute or more. This delay is caused by a limitation in how often Microsoft Windows updates SNMP values.

Below the Split Second Graph, the report displays the average CPU utilization percentages collected during the time period:

• Min Utilization %. The minimum CPU utilization percentage experienced.
• Max Utilization %. The maximum CPU utilization percentage experienced.
• Avg Utilization %. The average CPU utilization percentage across all sample data for this time period.

If multiple CPUs are available for the device and you have selected to show All CPUs in the Select CPU list, you can select the CPU(s) you want to display in the report body graph data. In the Summary section, click to select the check box(es) for the CPU graph(s) you want to display.

Note: Values displayed in the graph are the average values for the selected time period. Values displayed in the summary are the minimum, maximum, and average values for the selected time period. If raw polling data has been averaged into hourly or daily summarized data, the values for min and average, or maximum and average can be different. In some cases, they may be very different if there was a period of time when polled values were much higher or lower than normal.

You can verify your report rollup settings on the WhatsUp Gold console via Program Options > Report Data.

Note: If you are viewing data for all CPUs on a device the summary section displays the lowest of the minimum CPU utilization percentages experienced across all CPUs, and the highest of the maximum CPU utilization percentages experienced across all CPUs. The average CPU utilization percentage is calculated across all sample data for all CPUs

Select a CPU

Use the Select CPU list to select the specific CPU for which to view report data. You can select to view data for:

• A specific CPU to view a single performance graph for the selected CPU.
• All CPUs (average) to aggregate all CPU performance data into one graph.
• All CPUs to view individual performance graphs for each selected CPU overlayed on a single graph.

Date range

Use the date/time picker at the top of the report to select a date range and time frame.

In the Date range list, some reports also allow you to specify and customize the business hour report times for reports to display. This allows you to view the network activity only for specified business hours. The date and time format for the date on this report matches the format specified in Program Options > Regional set in the WhatsUp Gold console.
