The End of On-Call Chaos: How AI Automates RCA

By Kuldeep • Jan 15, 2026

Every SRE knows the feeling: The pager goes off at 3 AM. A dashboard is red. You are groggy, staring at a wall of logs, trying to figure out if it's the database, the network, or a bad deploy.

The traditional "runbook" approach is manual and slow. You grep logs, you check dashboards, you wake up other team members. This is the On-Call Chaos we all accept as normal. But it doesn't have to be.

Enter the AI SRE

Automated Root Cause Analysis (RCA) is changing the game. Instead of alerting you that "Something is wrong," AI agents like Rezmo immediately start an investigation.

They don't just read error messages. They:

• Analyze Context: Understanding topology and dependencies.
• Formulate Hypotheses: "Is this a memory leak? Or a downstream dependency timeout?"
• Verify with Data: Querying Prometheus/OpenSearch to confirm the theory.

Glass Box vs. Black Box

Trust is critical. Early AI tools gave you an answer but didn't show the work. Rezmo takes a "Glass Box" approach. We generate transparent investigation notebooks (graphs, queries, and logic) so you can verify exactly why the AI reached its conclusion.
