SQL Diagnosis

GaussDB(DWS) clusters support SQL diagnosis, which shows the complete execution plans of specific SQL queries. You can search for SQL queries (such as slow queries) using a combination of multiple filter criteria.

To use SQL diagnosis, perform the following steps:

  1. Log in to the GaussDB(DWS) console.
  2. Choose Dedicated Clusters > Clusters and locate the cluster to be monitored.
  3. In the Operation column of the target cluster, click Monitoring Panel.
  4. In the navigation pane on the left, choose Utilities > SQL Diagnosis. The metrics include:

    • Query ID
    • Database
    • Schema Name
    • User Name
    • Client
    • Client IP Address
    • Running Time (ms)
    • CPU Time (ms)
    • Scale-Out Started
    • Completed
    • Details

  5. On the SQL Diagnosis page, you can view the SQL diagnosis information. In the Details column of a specified query ID, click View to view the detailed SQL diagnosis result, including:

    • Alarm Information
    • SQL Statement
    • Execution Plan
