Top CPU Utilization Routers/Switches - Gauge/Table

The Top CPU view contains a list of routers and switches with the highest average CPU utilization during a selected timeframe.

A gauge-style chart shows average CPU utilization values from the indicated device. The table view provides bar charts of CPU utilization values, color-coded to indicate severity. In the table, the average CPU utilization levels during the selected time frame are broken out by individual processor. Only the devices with the highest CPU utilization during the reporting period are included.

Click the name of an item to see more data from that item.

By default, the Top CPU Utilization view for routers and switches includes the following information:

Device Name

Identifies the managed item that was the source of the performance data. If an administrator defined an alias for the device item, the alias is displayed. Otherwise, the discovered device name is displayed.

Name

Is the name of the individual processor.

Average Utilization

Is the average level of CPU usage on the indicated device, as a percentage of all available CPU time in the reporting interval.

Edit Table View Settings

You can change several settings for each view on a dashboard. In addition to providing a new title, you can change settings that are related to severity ratings. To ensure excellent performance in a large reporting environment, you can set an upper limit on the number of results that are returned. You can also select another group context for the data.

Follow these steps:

   The view Settings dialog opens.

2. Change the view Title or Subtitle to reflect the modified view.
3. Change the settings that are applied to the view if desired. Not all settings are available for all table view types:

   Measurement Settings

   Lets you select whether a total count or an average is displayed in the view.

   Moderate Status Start

   The lowest value for metrics that are displayed as Moderately Degraded in the view. Applies to the color-coding of gauge charts in gauge/table views.

   Default: Depends on the performance metrics reflected in the view. Click Use Defaults to revert to factory defaults.

   Critical Status Start

   The lowest value for metrics that are displayed as Critically Degraded in the view. Applies to the color-coding of gauge charts in gauge/table views.

   Default: Depends on the performance metrics reflected in the view.

   Results Limit (Max Rows)

   Limits the number of table rows that are returned by the associated database query to preserve monitoring-system performance.

   Direction Settings

   Lets you select the direction of data flow—either into or out of the interface.

   Affected % of reporting period

   Where available, sets the percentage of the reporting interval to which thresholds are applied.

   Default: 25%.

4. Click to expand nodes in the Context Settings area.
