Hi!  
I've a cluster with 3 nodes(3 master/2 data). This cluster is monitoring by Zabbix several weeks and now I notice, that metric "index\_time\_in\_millis"(curl -s [http://localhost:9200/index\_name/\_stats?pretty](http://localhost:9200/index_name/_stats?pretty) | jq ".\_all.primaries.indexing.index\_time\_in\_millis") is always growing since i started monitoring. Initially index\_time\_in\_millis show ~55000ms, now it's show ~1818000ms  
I thought this metric show average indexing time per document, and this time should have ~ same value. Something wrong with my cluster?
