The dell-csm-replicator supports monitoring of DellCSIReplicationGroup Custom Resources (CRs).

Each RG is polled at a pre-defined interval and for each RG, a gRPC call is made to the driver which returns the status of the protection group on the array.

If an RG doesn’t have any PVs associated with it, the driver will not receive any monitoring request for that RG.

This status can be obtained from the RG using a standard kubectl get call on the resource name:

NAME                                                 AGE     STATE   LINK STATE     LAST LINKSTATE UPDATE
