We're setting up a Elastic stack at our company. First to see it's usefulness (I'm sure it will be VERY useful for different departments), I got my hands on a 4 CPU, 16 GB RAM and 500 GB machine, running CentOS. For now only one node, I plan later to add more into a cluster.
Got some basic questions about recommended config setting to improve performace. I read through manuals, but still not quite sure if I'm getting the max out of the elasticsearch.
So what I'd like to now is recommended:
- ES JVM heap size (current -Xms2g, -Xmx2g)
-any other expert settings in ES JVM configuration
- Logstash initial and max siteof heap space (current -Xms256m, -Xmx1g)
-any other expert settings in Logstash JVM configuration
-LS Pipeline settings (current default)
I hope I'm ok to post this here. The stack is running, but I'm seeing some indexed data is missing although I don't see any problems with the input file or during the parsing process.
Thank you all!
