How to fix “Deflector exists as an index and is not an alias” warning?

[jochen]

• Stop Graylog
• Delete the offending index (which should be an alias instead, e. g. “graylog_deflector”): https://www.elastic.co/guide/en/elasticsearch/reference/5.6/indices-delete-index.html
• Start Graylog
• Optionally, cycle indices on the System / Indices / Index Set page with the “Maintenance” menu.

Sorry, but I’m new here.

1. how I can stop Graylog? I use appliance.
2. how I can talk with elastic? this page look like API documentation

Cycle indices with “Maintenance” menu does not help.

You can use any HTTP client, such as curl to send the HTTP DELETE request described on that page to the Elasticsearch node running in the virtual machine.
