I install the redis + logstsh indexer + elasticserch + kibana.
In each of my application server, the logstash agent is installed to pick up the logs.
Some of my logstash agent CPU spike up to 100%, some don't.
Is there a tool that can be used to diagnose what is logstash agent busy on?
We're working on a way to monitor Logstash's internal performance. We'll have metrics per second, per plugin, etc. This is targeted for Logstash 2.1 to 2.2, hopefully.
Sorry for the blind spot right now.
This will be cool feature, I am looking forward to it.
