It is advised to monitor both the DataCore Swarm resources and Veeam's ability to leverage them as with any storage target relied on to store backups. A combination of DataCore Swarm Monitoring (Grafana/Prometheus solution) and Veeam's monitoring capabilities (the Statistics tab in the Jobs node of the Veeam Management Console or more advanced options such as Veeam One Reporter) helps to keep the environment healthy.
