System Observability with ELK Stack

What is observability? Is it just monitoring on steroids? Better buy some observability, right? 'Observability' is not something that comes in a box. It is an attribute of the system you build, like usability and high availability. Simply collecting the data may result in too much information on disk and not enough time and intelligence when an incident occurs. The worst scenario comes out when the alert is from some days ago and responsibles don't have any tools to reconstruct that exact moment in the past. The problem is still there, but they don't have any way to understand what happened. Aktive Reply adopted ELK Stack and the "three pillars of observability" - metrics, logs, and application traces - to made tons of data actionable. No matter where the data was originated and when, all is stored inside the Elastic stack, easy to correlate, filter, and ready to go for customized dashboards and analysis.
