The Calendar Heat Chart - CPU Utilization assigns "heat" (severity) ratings to CPU utilization values and color-codes each heat category. The chart then plots heat patterns using colored blocks on a calendar table. You can modify heat values to reflect your unique environment.
Calendar Heat Chart views help engineers and managers identify patterns in utilization, latency, and loss metrics. Identifying such patterns can be a critical step in locating the source of performance issues that might appear to be intermittent. Usage patterns also aid in capacity planning for circuits, routers, servers, and other devices.
The CPU Utilization metric is based on average CPU usage over the time period selected for the view. Use this view to find patterns in CPU utilization metrics for each hour, day, and week of the month.
By default, the Calendar Heat Chart - CPU Utilization includes the following information:
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.
Is the average level of CPU usage on the indicated device, as a percentage of all available CPU time in the reporting interval.
