When initially installing the Elasticsearch DPKs, the initial Java Heap Size was set to 12G. Due to subsequent growth in data volume, the Heap Size needed to be increased. This was done by adding the ES_HEAP_SIZE environment variable and setting its value to 16G (ES_HEAP_SIZE=16G). However, after restarting Elasticsearch the ESCLUSTER.LOG still retained and reported the initial Heap Size of 12G.
This document provides the additional actions that need to be taken so that the relative entries in the ESCLUSTER.LOG file contain the correct, updated Java Heap Size.
- The ESCLUSTER.log can usually be found under the "<ES_HOME>/logs" folder on the Elasticsearch server. However, the location of the "logs" folder can be changed in the elasticsearch.yml file.
- The elasticsearch.yml and jvm.options configuration files can be found under the "<ES_HOME>/config" folder on the Elasticsearch server.
