Metrics & Mayhem

A CTO's guide to observability that actually works.

Your observability spend has never been higher. Your recovery times have never been worse.

Reality check: that is not a tooling problem. It is a leadership problem. Metrics & Mayhem is where that gap gets closed.

11 chapters. Kindle, paperback & hardback. From the Mastering Observability newsletter.

The problem isn't your tooling.

📕 Metrics & Mayhem: A CTO's Guide to Observability That Actually Works. Kindle is live now; paperback and hardback launched on 1 June.

In 2021, 47% of organisations took more than an hour to recover from an incident. By 2024, that figure was 82%. More tools, more dashboards, worse outcomes. The book names this the MTTR Paradox.

Eleven chapters, written for the CTO who has bought the platforms, run the training, and still can't get a straight answer when the system slows. You'll see what GitHub, Fastly and Atlassian did differently, and a phased plan you can start on Monday.

Signal Drop, the podcast

Five to seven minute audio notes from the front line of IT Ops. One idea, one habit, no theatre. Not interviews. Not news.

Seventeen episodes in, with Deep Dives when a topic earns the longer cut.

The newsletter that started it all

Metrics & Mayhem grew out of Mastering Observability, where the writing lands first, before it becomes a chapter or an episode.

One email. No noise. Unsubscribe whenever you like.

Who's behind it

Allan Mann

I've spent my career in IT operations leadership, the part of the org that gets paged when the abstraction leaks. Metrics & Mayhem is where I write down what actually works, what quietly doesn't, and what I got wrong the first time.

Comfortable is a warning light. This is the work of staying useful when it stops being comfortable.
