Identifying victim workloads involved in a performance event

In Unified Manager, you can identify which volume workloads have the highest deviation in response time (latency) caused by a storage component in contention. Identifying these workloads helps you understand why the client applications accessing them have been performing slower than usual.

Before you begin

About this task

The Dynamic Threshold Event Details page displays a list of the user-defined and system-defined workloads, ranked by the highest deviation in activity or usage on the component or most impacted by the event. The values are based on the peaks that Unified Manager identified when it detected and last analyzed the event.

Steps

  1. Display the Dynamic Threshold Event Details page to view information about the event.
    In the Workload Details table, the workloads are sorted on Victims - Peak Deviation in Latency.
    Note: When the table is sorted by peak deviation in latency, only user-defined workloads, such as volumes, are displayed. Workloads with very low latency values are not displayed in the table.
  2. Click the name of a volume to view its current and historical latency and events on the Performance/Volume Details page.
