If you observe frequent RPO violations, want to learn more about the network usage of vSphere Replication, or verify the status of your outgoing replications, you can view replication statistics for source and target vCenter Server sites.

You can view statistics for the replications for a certain time period. The transferred bytes statistics do not include the transferred data for the initial full synchronization, only the data transferred after the initial synchronization is complete. The update of the information in the statistics might occur in the end of the selected RPO period. For example, if you configure a replication with the default RPO of 1 hour, you might not see any transferred data for this VM in the statistics for up to 1 hour.

The granularity of the statistical data depends on the rrd-updater-interval parameter. The parameter is defined in the the/opt/vmware/hms/conf/hms-configuration.xml configuration file. This parameter controls the interval, at which the statistical data is saved. By default, the value is set to 5 minutes, but it can be changed if needed.
Note: Data is collected in 10 minute intervals and the graphs represent aggregated data for each interval. Therefore, you cannot see the exact moment when a peak value occurred and there might be an additional delay of up to 10 minutes before the Transferred Bytes statistics display the data. The displayed data combines all site pairs.
  • Transferred Bytes - total bytes transferred for all outgoing replications, excluding the data from the initial full synchronization.
  • Replications Count - number of outgoing replications.
  • RPO Violation Count - number of RPO violations.
  • Target Sites Count - number of vSphere Replication site connections.
  • VR Sites Count - number of registered replication servers.


Verify that vSphere Replication is running.


  1. Log in to the vSphere Client.
  2. On the home page, click Site Recovery and click Open Site Recovery.
  3. On the Site Recovery home page, select a site pair and click View Details.
  4. Click the Site Pair tab and click vSphere Replication reports.


The Reports page displays historic data for vSphere Replication for a certain time period.
