Once your panel is enabled, you will notice several types of notifications.

The notification panel is the section that will provide suggestions to optimize your cluster.

How to access it?

  • In the Cluster View screen

  • In the dashboard of the Data View screen

Notifications are organized into 3 groups: INFOS, WARNING, and DANGER

Each notification comes with a way to address the issue.

By clicking on a notification, you will be able to see the details and a button to address it.

WARNINGOPTIMIZE_TABLEDisplay when a table has a percentage of queries using the main index only. You should run the optimizer to create new indexes

Display when an index size is approaching index.memory.max_size.mb. Two thresholds, in notifications.json, define the gravity of the notification.
