Resource Reports

Information about the resources used by the virtual machines being recovered to a particular site is displayed in the Resources report under the Reports tab. The information is collected at fixed times that are defined in the Reports tab of the Site Settings dialog in the recovery site. Information for the report is saved for 90 days when the sampling period is hourly and for one year when the sampling period is daily.

The report collects the resource information for the virtual machines being recovered to the site where the report is run.

If no virtual machines are recovered to the site where the report is run, the report is empty.

You can filter the information by the following:

From and To: The dates for which you want information.

Click Export to generate the report, which is produced as an Excel file.

The information presented in this report is divided into three tabs:

Details Tab shows information for each protected virtual machine.

Performance Tab shows bandwidth and throughput information for each virtual machine in a table and in a graph.

Target Host Tab shows information per host in the recovery site.

Using a REST API to Generate a Report

Zerto exposes a REST API to produce resource data. The report is generated by passing a URL. For details about the ResourcesReport API (and all other Zerto REST APIs), see the Zerto Virtual Replication RESTful APIs.

Details Tab

The Details tab includes the names and IDs of the virtual machines being protected and, for each virtual machine, the timestamp for the information, where it is protected, the CPU used, the memory used by the host and the guest, the storage used, and other information.

Interpreting the Details Tab

The Details tab provides a breakdown of every protected virtual machine, identified by its internal identifier and name in the hypervisor manager. The report also includes the name of the VPG that is protecting the virtual machine and information such as the protected and recovery sites, the protected and recovery vCD Org, cluster, etc.

The Timestamp column displays the time when the last sample, as defined in the Reports tab of the Site Settings dialog, was taken.

The VPG Type column is one of:

The ZORG column defines organizations set up in the Zerto Cloud Manager that use a Managed Service Provider for recovery.

The Bandwidth (Bps) and Throughput (Bps) columns display the average between two consecutive samples. With daily samples, these figures represent the average daily bandwidth and throughput. For hourly samples, the timestamp represents an average between the sample at the timestamp and the previous sample. A value of -1 means that the system failed to calculate the value, which can happen for several reasons, for example:

Bandwidth is calculated as: (currentValue – valueInLastSample)/elapsedTtime

Report output fields

The following describes the fields in the Details tab.

Performance Tab

The Performance tab shows bandwidth and throughput information for each virtual machine per sampling period in a table and in a graph. The Performance tab enables the user to view the total bandwidth and throughput per sampling period.

The graph allows the user to view performance trends over time per VM.

For full explanation of the bandwidth and throughput information, refer to the Details Tab.

You can filter information by date and VM name.

The following describes the fields in the Performance tab:

Target Host Tab

The Target Host tab shows information per host in the recovery site. This enables the user to perform capacity planning on the recovery host. You can filter information by time and by host.

The following describes the fields in the Target Host tab.
