Elasticsearch is about to reach the maximum number of shards it can host, based on your current settings

Can this issue cause problem that it doesnt show log in Kibana. ps. Im new in elastic.

I think you might have too many shard. limit I belive was 1000 shard per node. after that you will see unexpacted result from elastic.

what is cluster health output?

curl -u user:passwd host:9200/_cluster/health?pretty
