Review Druid's logging configuration
Closed, ResolvedPublic3 Estimated Story Points

Description

From @Nuria's email on Analytics internal we should:

  1. Set up indexing-logs (eg. /var/lib/druid/indexing-logs)
  2. Review daily log rotation in /var/log/druid (probably the log4j config of the root logger) since we are logging tons of things that might not be needed.

Event Timeline

To be clear indexing logs are present but just in one of the three machines. Pulling would need to be set up for application logs and indexing logs, specially application logs as they are full of heart beats.

I went ahead and just added the cron jobs. If we learn of a way to use log4j for the requests logs, we can revisit this then.
