VMware Device Datastore IOPS

VMware Device Datastore IOPS report reveals the average count of raw I/O operations per second (IOPS) for a virtual machine This report is helpful for diagnosing read and write efficiency and in some cases memory exhaustion.

High IOPS metrics can indicate virtual memory usage where RAM needs exceed allocation. Use this report together with the VM Memory Utilization and Disk Activity report.

Disk. Disk name (index in parenthesis).
Poll Time. Date and time of last poll.
Average Read Requests per Second. Average disk operations per second.
Average Write Requests per Second. Average disk operations per second.

Generate a report

Choose Device. Choose one or more host devices you want VMware Device Datastore IOPS information for.

Choose time constraints. (,) Choose times for the VMware Device Datastore IOPS. (For recently observed measurements, select Last Polled from the Date Range drop down list.)

Filter and reduce by row and by column. Sort and remove columns, group rows based on specific column values, and remove unwanted information from the table.

Chart, adjust output, and visualize. Fine tune report presentation and range of values displayed using the Report Settings dialog (optional).

Note: This report only returns VMware Device Datastore IOPS metrics for virtual machines when host machines have the appropriate VMware credentials. For more information, see Using Credentials.

Export report data

Report data can be exported from WhatsUp Gold, reused, and distributed in multiple formats. Select Expand () from the Dashboard Options () menu. After the report has been expanded, select the Export Data icon to access the following options:

HTML. Generate and download a .htm file presenting your report data as it appears in the WhatsUp Gold user interface.
Excel. Generate and download a .xml spreadsheet containing your report data.
CSV. Generate and download a .csv file containing your report data.
Text. Generate and download a .txt file containing your report data.
Schedule Export. Set a recurring date and time, format, and email destination for report data export.
Important: Current report data file format options are only applicable to export schedules created using WhatsUp Gold version 2021 and later. Any report data export schedule created using an earlier version of WhatsUp Gold will still result in a .PDF output until that schedule is removed from, then recreated in the Scheduled Reports Library using the latest version of WhatsUp Gold.
