Enabling the OpsCenter Performance Service

Enable the OpsCenter Performance Service. Enabling each performance object also enables its default configuration.

1. Click cluster name > Services.
2. Click the Configure or Details link as appropriate for the Performance Service.
   The Overview page prompts you to enable metrics.

   

3. Click the Enable metrics link to view performance data.
   The Settings tab appears where you can enable and configure the performance objects.

   

4. Click the toggle in the Status column to On for the performance objects you want to enable.
   The performance objects can be turned on and used independently. Turning on a performance service object enables the associated settings in the dse.yaml file.

   A dialog prompts you to confirm. Toggling performance objects from off to on has the following effect:

   Clusters not managed using LCM

   For clusters not managed using LCM, changes are pushed to dse.yaml on every node, which overwrites any comments or formatting in the dse.yaml file. To retain your original dse.yaml, make a backup of the file as mentioned in the above prerequisite.

   Clusters managed using LCM

   For clusters managed using LCM, you must manually update any configuration profiles to persist changes to dse.yaml related to the performance service. See Editing a configuration profile.

   

5. Click Change to proceed.
   No further configuration is required; however, you can adjust the default configuration parameters:

   • Configuring the slow query log
   • Configuring table metrics
   • Configuring thread pool statistics
