Creating a query monitoring rule - Amazon Redshift
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Creating a query monitoring rule

You can use the Amazon Redshift console to create and modify WLM query monitoring rules. Query monitoring rules are part of the WLM configuration parameter for a parameter group. If you modify a query monitoring rule (QMR), the change happens automatically without the need to modify the cluster. For more information, see WLM query monitoring rules.

When you create a rule, you define the rule name, one or more predicates, and an action.

When you save WLM configuration that includes a rule, you can view the JSON code for the rule definition as part of the JSON for the WLM configuration parameter.

To create a query monitoring rule

  1. Sign in to the Amazon Web Services Management Console and open the Amazon Redshift console at https://console.amazonaws.cn/redshiftv2/.

  2. On the navigation menu, choose Configurations, then choose Workload management to display the Workload management page.

  3. Choose the parameter group that you want to modify to display the details page with tabs for Parameters and Workload management.

  4. Choose the Workload management tab, and choose Edit workload queues to edit the WLM configuration.

  5. Add a new rule either by using a predefined template or from scratch.

    To use a predefined template, do the following:

    1. Choose Add rule from template in the Query monitoring rules group. The list of rule templates is displayed.

    2. Choose one or more rule templates. When you choose Save, WLM creates one rule for each template that you choose.

    3. Enter or confirm values for the rule, including Rule names, Predicates and Actions.

    4. Choose Save.

    To add a new rule from scratch, do the following:

    1. To add additional predicates, choose Add predicate. You can have up to three predicates for each rule. If all of the predicates are met, WLM triggers the associated action.

    2. Choose an Action. Each rule has one action.

    3. Choose Save.

Amazon Redshift generates your WLM configuration parameter in JSON format and displays it in the JSON section.
