Dear Marcus, special thanks for your comments. Please just a brief question: I have this line in /etc/default/graylog-server (considering I defined the HEAP SIZE = 16GB for Elasticsearch):
GRAYLOG_SERVER_JAVA_OPTS="-Xms16g -Xmx18g -XX:NewRatio=1 -XX:PermSize=256m -XX:MaxPermSize=512m -server -XX:+ResizeTLAB -XX:+UseConcMarkSweepGC -XX:+CMSConcurrentMTEnabled -XX:+CMSClassUnloadingEnabled -XX:+UseParNewGC -XX:-OmitStackTraceInFastThrow" What's the meaning of -XX:PermSize=256m -XX:MaxPermSize=512m ??? Do I have to increase these options? Thanks again, regards. 2016-07-27 5:28 GMT-03:00 Marcus Franke <[email protected]>: > Hi Roberto, > > If you have performance issues with the processing, then you have two > choices: > > Have a look into your server.conf settings. > There are several options to possibly speed up the output performance > output_batch_size defaults to 25?
