Could Not index event to ElasticSearch

May I see the full logs please? I mean at least the logs from the start until you see that the node has been started.

The log is too large to send the entire log. But this is the logfile /var/log/elasticsearch after a restart

I am unfamiliar with how to do this. Can you give me the command to do this?

{
  "error" : {
    "root_cause" : [
      {
        "type" : "index_not_found_exception",
        "reason" : "no such index [_cluster]",
        "resource.type" : "index_expression",
        "resource.id" : "_cluster",
        "index_uuid" : "_na_",
        "index" : "_cluster"
      }
    ],
    "type" : "index_not_found_exception",
    "reason" : "no such index [_cluster]",
    "resource.type" : "index_expression",
    "resource.id" : "_cluster",
    "index_uuid" : "_na_",
    "index" : "_cluster"
  },
  "status" : 404

}

The command is in the docs I linked to.

When I run the command with curl, this is my output:

  "error" : {
    "root_cause" : [
      {
        "type" : "index_not_found_exception",
        "reason" : "no such index [_cluster]",
        "resource.type" : "index_expression",
        "resource.id" : "_cluster",
        "index_uuid" : "_na_",
        "index" : "_cluster"
      }
    ],
    "type" : "index_not_found_exception",
    "reason" : "no such index [_cluster]",
    "resource.type" : "index_expression",
    "resource.id" : "_cluster",
    "index_uuid" : "_na_",
    "index" : "_cluster"
  },
  "status" : 404

What is the exact command you run?

I just spotted something in the logs you provided earlier. It appears you have hit the 1000 shards per node limit. If this is correct I would recommend reducing the number of shards in the system significantly.

curl -X Get "XXX.XXX.XXX.XXX:9200 /_cluster/stats/=human&pretty"

Where the XXX's are the ip of the Elasticsearch server
localhost does not work or configured.

Awesome, yes, I did see that as well.
What is causing the shards, and how do I reduce them?

You can delete data and make sure indices you are creating get reasonably large, e.g. by switching from daily to monthly or weekly indices.

Link for me on this?
