Hi ,
In Elasticsearch:7.9.2 we are getting Query latency and Flush Latency alert. We setup this new cluster and moved it from standalone ES cluster to 3 node cluster in kubernetes. We are monitoring ES cluster with Zabbix and since we moved we are started getting Flush and Query Latency. We left with Default settings and given heap size of 33% of memory allocated. No issue with resources from server side and we are using SSD disk.
