This report aggregates historical data and shows performance statistics for all hosts in selected clusters across a time range. The report features a predefined list of performance counters and allows you to report on memory, CPU, disk and network usage.
The report shows performance charts with resource usage statistics for hosts in each cluster included in the report scope, rates the hosts by the resource usage level, and analyzes the resource usage trend for each host.
Click a host name in the Summary or in a resource usage table to drill down to performance charts with statistics on CPU, memory, disk and network usage for the host. The report will show a list of top resource consuming VMs. You can 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.
The report provides an overview of hardware resource consumption across your hosts. This information may help you identify hosts with performance issues, balance workloads, right-size resource provisioning, redefine DRS settings and optimize cluster overall performance.
You can specify the following report parameters:
- Scope: defines a virtual infrastructure level and its sub-components 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 scope. Otherwise, the report will contain no data.
- Counters: defines a list of performance counters to analyze in the report.
- 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.
