The following table lists the agent actions available for the Elasticsearch KM.
Sync Inventory: Destroys the stale or inactive instances and displays the updated inventory.
List RED Indices: Displays a list of indices with Red status.
Red status indicates that at least one primary shard (and all of its replicas) is missing.
This means that you are missing data. Searches will return partial results, and indexing into that Shard will return an exception.
