The Calendar Heat Chart - Percent Memory Utilization assigns "heat" (severity) ratings to memory 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 Memory Utilization metric is an average utilization statistic derived from the percentage of available memory in use at a given moment, averaged over the reporting period. Use this view to find patterns in memory utilization metrics for each hour, day, and week of the month.
By default, the Calendar Heat Chart - Percent Memory 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.
Indicates the amount (percentage) of memory capacity being used; derived by dividing used memory by total memory.
