The Virtual Infrastructure Described table will provide an overview for the cluster included in the report scope: number of hosts, number of VMs (total, active, shutdown and suspended) and total CPU and memory usage values.
The Performance Forecast Analysis and Recommendations table will provide details and recommendations for the resource which utilization threshold will be breached first within the forecast period.
In this example, only one cluster is reported to run out of CPU and memory within the forecast period. The number of Days Left shows 14-21, which means that the cluster will be able to sustain the current workload from 14 days (in the worst-case scenario) to 21 days (in the best-case scenario) . The Recommendation section provides practical recommendations for maintaining the resource usage within the desired threshold.
The Performance Forecast section will show a chart and a details table for each analyzed cluster resource.
The performance forecast tables reveal whether the specified thresholds will be breached and detail the following forecasted values (all values are provided for both the best-case and the worst-case scenarios):
|•||Days Left: number of days after which CPU and memory utilization thresholds will be breached|
|•||Metric Forecast: predicted metric value at the end of the forecast period|
|•||Available resources: amount of resources that will remain unused on the forecast horizon date (available resources, calculated as the difference between the threshold and the predicted resource usage)|
In this example, the cluster is forecasted to run low on memory resources and CPU resources in the worst-case scenario.
You can expand the table rows to open charts detailing actual CPU and memory utilization values, calculated utilization trend and its deviation, and the threshold.
