Types of workloads monitored by Unified Manager

Contributors netapp-chikkusu

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 volume, LUN, NFS share, SMB/CIFS share, and a workload 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. (DP volumes are monitored for user-generated traffic.)

    • 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.
