You can use Unified Manager to monitor the performance of two types of workloads: user-defined and system-defined.
- User-defined workloads
- The I/O throughput from applications to the cluster. These are processes involved in read and write requests. A FlexVol volume or FlexGroup volume is a user-defined workload.
Note: Unified Manager only monitors the workload activity on the cluster. It does not monitor the applications, the clients, or the paths between the applications and the cluster.
- If one or more of the following is true for a workload, it cannot be monitored by Unified Manager:
- It is a data protection (DP) copy in read-only mode. (Note that DP volumes are monitored for user-generated traffic.)
- It is an Infinite Volume.
- It is an offline data clone.
- It is a mirrored volume in a MetroCluster configuration.
- System-defined workloads
- The internal processes involved with storage efficiency, data replication, and system health, including:
- Storage efficiency, such as deduplication
- Disk health, which includes RAID reconstruct, disk scrubbing, and so on
- Data replication, such as SnapMirror copies
- Management activities
- File system health, which includes various WAFL activities
- File system scanners, such as WAFL scan
- Copy offload, such as offloaded storage efficiency operations from VMware hosts
- System health, such as volume moves, data compression, and so on
- Unmonitored volumes
Performance data for system-defined workloads is displayed in the GUI only when the cluster component used by these workloads is in contention. For example, you cannot search for the name of a system-defined workload to view its performance data in the GUI. If multiple system-defined workloads of the same type are displayed, a letter is appended to the workload name. The letter is intended for use by support personnel.
