Calendar Heat Chart - Average Percent Utilization Out

The Calendar Heat Chart - Interface Average Percent Utilization Out assigns severity ratings to inbound interface utilization values and color-codes each severity category. The chart then plots the severity using colored blocks on a calendar table. You can modify severity 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 Interface Utilization metric is based on average outbound (sending) interface usage over the time period selected for the view. Use this view to find patterns in interface utilization metrics for each hour, day, and week of the month.

By default, the Calendar Heat Chart - Interface Average Percent Utilization Out includes the following information:

Device Name

Interface
