Cluster Performance

This report aggregates historical data and shows performance statistics for a selected cluster across a time range. The report shows statistics on CPU, memory, disk and network usage for the cluster, lists top resource consuming hosts and calculates resource usage trends for them.

Cluster Performance Tip:

Click a host name in the Summary table or in the list of top resource consuming hosts to drill down to performance charts with statistics on CPU, memory, disk and network usage for the host.
Click a VM name in the list to drill down to performance charts with statistics on CPU, memory, disk and network usage for the VM.

Use Case

The report provides an overview of hardware resource consumption for the selected cluster. This information may help you identify clusters with performance issues, balance workloads, right-size resource provisioning, redefine DRS settings and optimize cluster overall performance.

Report Parameters

You can specify the following report parameters:

Object: defines the cluster to analyze in the report.
Interval/Start Date - End Date: defines the time period to analyze in the report. Note that the reporting period must include at least one data collection session for the selected cluster. Otherwise, the report will contain no data.
Top N: defines the maximum number of hosts and VMs to display in the report output.
Business hours from - to: defines time of a day for which historical performance data will be used to calculate the performance trend. All data beyond this interval will be excluded from the baseline used for data analysis.
