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.
