How Do I Clear Elasticsearch Indexes in CSS?

Before deleting index data, carefully evaluate any potential impact on services.

Have indexes automatically cleared on a regular basis.
You can create a scheduled task to execute an index deletion request periodically.

For details about Open Distro Index State Management, see https://opendistro.github.io/for-elasticsearch-docs/docs/im/ism/.
Manually clear indexes.
- Log in to Kibana and run the DELETE / Index name command in Dev Tools.
- Log in to Cerebro, search for the target index name, click the index name, click delete index, and click Confirm in the displayed dialog box.
