We had one problem that would pop up out of nowhere...
Another serious issue was when agents started to produce massive amounts
of data. For example, the logs produced by 1 machine was maybe
1mb/minute but when the agent was unable to communicate with any
collectors for what ever reason it would fill up with GB's of data
sitting in one of flumes subfolders (sent, sending, completed, etc).
Any links on how to create some real time analysis using kafka?
