Defining Workload Views Manually

Steps for manually defining your workload views.

This task describes how to manually define your Workload Views.
  1. Verify that you are logged in to the Workload XM web UI.
    1. In the URL field of a supported web browser, enter the Workload XM URL that you were given by your system administrator and press Enter.
    2. When the Workload XM Log in page opens, enter your Workload XM user name and password access credentials.
    3. Click Log in.
  2. In the Search field of the Clusters page, enter the name of the cluster whose workloads you want to analyze.
  3. From the time-range list in the Cluster Summary page, select a time period that meets your requirements.


  4. From the navigation panel, select Workloads.
  5. In the Workloads page, click Manual:


    The Define Workload View widget opens, where you define a set of criteria that enables you to analyze a specific set of queries.
    For example, as shown in the image below, you can list the total amount of failed queries, as a percentage, from a specific engine that are subject to a two second SLA.
    Where, as defined by the criteria condition, Workload XM will monitor all query jobs from the Impala engine. When the total query execution time exceeds 2 seconds, as defined by the SLA condition, for 90 percent of these queries, as defined by the Warning Threshold, the workload is flagged with a failed state:


  6. (Optional) To display a summary of the queries matching your criteria, click Preview. Which displays the date range, the number of queries that match the criteria, and the number of queries that missed the SLA condition.
  7. When you are satisfied with the results, click Save.
    The Workloads page opens and your workload view appears in the Workload column.


  8. (Optional) To view more information about the workloads using the view's formula, open the Summary page by clicking the name of the workload view in the Workload column, which visually displays the view's details as chart widgets that you can use to further analyze the results.
    The following examples, display how this group of queries are meeting the Workload view's SLA in the Trend chart, where:
    • The Count tab, displays the number of executing queries, either By Status or By Statement Type. To view further details, click the Total Queries, the Failed Queries, or the Query Active Time value.


    • The Concurrency tab (which is not available for CDP), displays the number of queries executing concurrently.
      In the following example, the maximum concurrency for this view is 328. This indicates that for the queries monitored by this view, 328 queries accessed the same data at the same time during the specified time period. The graph view displays how the concurrency fluctuates over the date range specified for the workload view.
