About the Workload Manager User Interface

Provides a brief introduction to the web interface and frequently used interface elements of Workload Manager.

The Workload Manager UI displays graphical reports of the health, performance, and status of your workloads, workload clusters, and resources. Its dashboard components include statistics, performance, health, and prescription guidance visually displayed in chart widgets or tabular views.

The navigation side-bar enables access to the following Workload Manager features and engine services:
  • Summary, which opens the Cluster Summary page that visually displays information about your cluster and engine health.
  • Workloads, which opens the Workload Views page that enables you to create, view, monitor, and manage views specific to your business requirements.
  • Auto Actions, which opens the Auto Actions page that enables you to create, view, monitor, and manage your Auto Actions.
  • Chargeback, which opens the Chargeback page that enables you to create, view, monitor, and manage cost centers specifically for your workloads.
  • Engines, which lists the Workload Manager engine workload services:
    • Impala
    • Spark
    • Hive
    • Oozie
    • MapReduce

    When an engine is selected, the engine's chart widgets display information about the workloads serviced by the selected engine, such as which jobs or queries have failed or are slow, their processing time, missed SLAs, user and pool metrics, and outlier issues. The Impala and Workload View chart widgets also display information about the CPU and Memory usage, the tables used for your Impala queries, and the SQL statement types.

About the Workload Manager Chart Widgets

The Workload Manager chart widgets enable you to quickly observe real-time and historical patterns, trends, and outliers of your workload data. They provide quick insights into the health and performance of your workloads, clusters, and resources. Where:
  • Hovering over an element with your mouse pointer, such as over a time-line or a data point, displays more information about the element underneath.
  • Clicking a link within a chart widget or a bar within bar chart widget, such as the Suboptimal bar chart widget, opens the engine's Jobs or Queries page that contains more information in a tabular view for you to investigate further.

About the Jobs and Queries Pages

Depending on the engine chosen, the engine's Jobs or Queries page provides information about each of the jobs or queries that are serviced by the engine. You can filter further by selecting a filter option from one of the filter categories; Pool, User, Status, Health Check, or Duration.

For more information about a specific job's or query's health, execution details, baseline, and trends, open their respective page by clicking its link in the Job or Query column and selecting the tab of interest. As well as providing more details for you to investigate further, these pages also provide prescriptive guidance and recommendations that enable you to address and optimize problems.
