grayog web interface was receiving 502 bad gateway issues. When I checked I found My ELasticache in red state.

```auto
{"cluster_name":"graylog","status":"red","timed_out":false,"number_of_nodes":1,"number_of_data_nodes":1,"active_primary_shards":0,"active_shards":0,"relocating_shards":0,"initializing_shards":4,"unassigned_shards":24,"delayed_unassigned_shards":0,"number_of_pending_tasks":7,"number_of_in_flight_fetch":1,"task_max_waiting_in_queue_millis":11,"active_shards_percent_as_number":0.0|

```

Output of `sudo curl -XGET localhost:9200/_cat/shards`:

This depends on whether you want to keep all the log messages you’ve indexed so far.

As long as you’ll use the official Elasticsearch Delete Index API, it should be safe: [https://www.elastic.co/guide/en/elasticsearch/reference/2.4/indices-delete-index.html](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/indices-delete-index.html)
