    "root_cause" : [
      {

        "reason" : "failed to process cluster event (cluster_update_settings) within 30s"
      }
    ],
    "type" : "process_cluster_event_timeout_exception",
    "reason" : "failed to process cluster event (cluster_update_settings) within 30s"

That should be fine also for larger clusters. It may be worthwhile investigating while it is taking so long instead of trying to increase it.

Which version of Elasticsearch are you using? How many nodes do you have in your cluster? How many indices and shards do you have in the cluster?

I do not understand this metric. What is it?

That is over 2800 shards per data node, which is far too much. I suspect you will need to reduce this. Have a look at the blog post I linked to for some guidelines on shard count and size.

It is in my previous post where I asked about the unit.

Increasing queue sizes and timeouts like you have done does not solve the problems you are having in the cluster, just putting a band-aid on it. I would recommend trying to address the underlying issues while your cluster still is in a workable state. The worse state you cluster gets in, the more difficult it will be to solve any problem properly.

I think this might be [what you are looking for](https://www.elastic.co/guide/en/elasticsearch/reference/5.6/modules-discovery-zen.html#_cluster_state_updates).
