Over the weekend I saw a number of
java.lang.OutOfMemoryError: Java heap space errors in the logstash logs. After reading the docs I've tuned the default settings up to 16G (32GB Server) however I'm are still seeing
JVM Heap: 99.80% (16GB / 16GB) in the kibana monitoring screen.
Kibana monitoring screen attached showing cluster info, this is still very much a proof of concept at this stage so we will absolutely be looking at how we are indexing at replicating data before going live.
Is this normal behaviour for logstash, or do I have a memory leak somewhere. If this is not normal behaviour, how would I go about trying to debug this.
