I am new to ELK and I am trying to figure out this heap problem I am having. I am trying to search the site here, but I get multiple results on how to set heap and on what parts of ELK need the heap size adjusted.
I am pretty sure that Elasticsearch is where I need to adjust the heap setting.
I modified /etc/sysconfig/elasticsearch with ES_HEAP_SIZE=4g, but when I check that in Kibana, it's not showing 4gb as heap total.
I also restarted the service for Elasticsearch and it still only showing about 800mb heap total.
Any help would be appreciated. Thank you.
