Heap size filling up but CPU usage remains very low


(Ben) #1

I have a very basic passthrough logstash instance with a single http input, one date formatting filter, and two outputs, one to s3 and one to another logstash instance.

I upgraded to 6.1 recently, but am continuing to see an issue where my CPU is far from saturated but my heap usage slowly creeps up over a few days.

How can I leverage more of the CPU resources and is it even right to think of it as a balancing act between memory usage and CPU usage?

Thank you!
