Observability strategy, incident leadership and AI operations for the people who are accountable when it breaks. Written by Allan Mann, with nothing to sell you but the thinking.
Twenty-five years running IT operations and observability across five tier-1 banks and one UAE government, the environments where "it looked fine on the dashboard" ends up in front of a regulator.
Author of Metrics & Mayhem: A CTO's Guide to Observability That Actually Works. Host of the Metrics & Mayhem podcast. Vendor-neutral by construction: no platform reselling, no vendor sponsorship, no referral fees.
This is not. No vendor sponsorship, no reference architecture that happens to need three seats of something. Just what actually holds up in a large enterprise, and what quietly does not.
OpenTelemetry is not what is blocking you. Ownership boundaries, funding models and the team that will not go first are. Those are the pieces nobody writes about.
Cardinality, retention and sampling get chosen by accident, then defended for two years. Decide them on purpose and the invoice stops being a surprise.
Autonomous SRE agents will run queries you would never approve and spend budget while they think. The question is where accountability actually sits.
Chapter 4 of Metrics & Mayhem. The chapter that answers the question every engineering leader is afraid to ask out loud: when it breaks, who actually owns getting it back?
