Centralizing pm2 logs with elastic search/kibana/logstash

Question

I was wondering if there was a way to centralize pm2 logs by either sending them to elastic search or integrating pm2 with the ELK stack in some way.

Answer 1

I would suggest you to use a pm2 module which would send logs to logstash using PM2's pm2.launchBus(errback) api (http://pm2.keymetrics.io/docs/usage/pm2-api/).

As you can see here https://github.com/cliv/pm2-gelf/blob/master/app.js#L24 It's pretty straight forward. The module listens pm2's log events and sends logs using gelf protocol in this case.
