Click a VM name in the list of top 3 resource consuming VMs to drill down to performance charts with statistics on CPU, memory, disk and network usage for the VM. ## Report Parameters You can specify the following report parameters: - **Object**: defines the datastore to analyze in the report. - **Period**: defines the time period to analyze in the report. Note that the reporting period must include at least one successfully completed *Object properties data collection* task for the selected datastore. Otherwise, the report will contain no data. - **Business hours only**: 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.
