Problem with cluster.max_shards_per_node

Good day
I have a problem
:_type=>"_doc", :routing=>nil}, #LogStash::Event:0x23cacf18], :response=>{"index"=>{"_index"=>"logstash-nginx-domain", "_type"=>"_doc", "_id"=>nil, "status"=>400, "error"=>{"type"=>"validation_exception", "reason"=>"Validation Failed: 1: this action would add [2] total shards, but this cluster currently has [1000]/[1000] maximum shards open;"}}}}

but in my elasticsearch setting


I see cluster.max_shards_per_node=5100
where mistake?

What is "total_shards_per_node"?
https://www.elastic.co/guide/en/elasticsearch/reference/current/allocation-total-shards.html
Normally it´s not set. But I have no other idea at this time.


this setting by default
