Frequently Asked Questions
What is the difference between monitoring and observability?
Monitoring tells you that a system is broken. Observability gives you the deep, contextual data (logs, metrics, traces) needed to figure out exactly why it broke and how to fix it.
Why is a blameless culture critical for postmortems?
If engineers fear being fired for a mistake, they will hide the truth. A blameless culture ensures psychological safety, so the team can uncover the real systemic flaws that allowed the error to happen.
What makes a good postmortem document?
A timeline of the incident, the root cause analysis (the 5 Whys), the customer impact, and most importantly, concrete action items to prevent the exact same failure from recurring.
