Introduction: Centralized Logging

Overview

We used to store logs in files. That wasn’t so bad when we only had a few applications and they were running on dedicated servers. Finding logs was easy given the nature of static infrastructure. Locating issues was easy as well when there was only an application or two. But times have changed. Infrastructure grew in size. Now we have tens, hundreds, or even thousands of nodes. The number of applications has increased as well. More importantly, everything has become dynamic. Nodes are being created and destroyed. We started scaling them up and down. We began using schedulers, and that means our applications started “floating” inside our clusters.
