The Server Manager:
-
Monitors the ScaleIO status by periodically polling using the REST API. Below ScaleIO components are monitored through REST API:
-
DataStorageService (SDS)
-
StorageClientService (SDC)
-
PhysicalDisk ( Disk/Device)
-
StorageManagementService ( MDM)
-
StorageManagementServiceGroup ( MDM-Cluster)
-
StorageServiceGroup ( ProtectionDomain)
-
StoragePool ( Monitoring supported only for ScaleIO 2.0 version and above due to Alert API support added from ScaleIO 2.0 onwards)
-
-
Generates notifications when:
-
A PhysicalDisk is down.
-
A ProtectionDomain is inactive.
-
A SDS/MDM/SDC is disconnected.
