Using data persistence, you can avoid data gaps in case of temporary connectivity issues. Activate data persistence to allow the cloud proxy to store data that is sent to VMware Aria Operations, if the connection fails between the cloud proxy and VMware Aria Operations. The cloud proxy stores all the persisted data that includes metrics and properties, along with time stamps.

Cloud proxy can store data for a maximum duration of one hour. If there is lack of space or if the connection fail lasts for more than an hour, the cloud proxy rotates the stored data by deleting the oldest stored data and replacing it with the most recently collected data. In case of lack of space, you can add additional storage, for more information, see KB article 2016022.

Once the connection is restored, the cloud proxy sends the stored data to VMware Aria Operations before the real-time data. The stored data is displayed before the real-time data as data is displayed in the correct time series. If the connection loss was more than one hour, there can also be a gap in the displayed data.

You can activate data persistence when you deploy a new cloud proxy. For more information, see Configuring Cloud Proxies in VMware Aria Operations. You can also activate data persistence in an existing cloud proxy. For more information, see Monitoring the Health of Cloud Proxies.
