- SQLServerVolumeSpace - uses `sys.dm_os_volume_stats` to get total, used and occupied space on every disk that contains a data or log file. (Note that even if enabled it won't get any data from Azure SQL Database or SQL Managed Instance). It is pointless to run this with high frequency (ie: every 10s), but it won't cause any problem.
|
||||
- SQLServerCpu - uses the buffer ring (`sys.dm_os_ring_buffers`) to get CPU data, the table is updated once per minute. (Note that even if enabled it won't get any data from Azure SQL Database or SQL Managed Instance).

- SQLServerAvailabilityReplicaStates: Collects availability replica state information from `sys.dm_hadr_availability_replica_states` for a High Availability / Disaster Recovery (HADR) setup
