I have cluster yellow because this line, but dont know what is wrong, any idea?
[2017-07-13T16:21:39,946][INFO ][o.e.c.r.a.AllocationService] [elastic01] Cluster health status changed from [RED] to [YELLOW] (reason: [shards started [[.kibana][0]] ...]).
How many nodes do you have? If you only have one node, yellow is expected. Yellow means that all the primaries are allocated, but one or more replicas are missing. Elasticsearch won't allocate replicas to the same node as the primary, so if you only have one node your cluster will be in yellow status.
It's not really a problem, just a notice to let you know.
