I am running CentOS, and I have ELK(ElasticSearch, Logstash, Kibana) and Graphite, Graphana on this VM.
When I run top I can see ES is the culprit
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
899 elasticsearch 20 0 6110m 1.2g 35m S 100.0 31.3 1262:28 java
I don't know why it started acting like this. I was told hot threads will help but I am new to ES and need help to understand it.
