How do I delete all mention of metrics from my Swarm Search cluster?

curl -i -XDELETE "http://[Elasticsearch IP]:9200/metrics"

That will remove all of the metrics indices. Make sure you also uninstall the metrics_curator and cron job.

There is documentation on resetting metrics which is preferred if you want to use metrics in the future: /wiki/spaces/DOCS/pages/2443813515
