# Mastering Observability > Mastering Observability is for IT and engineering leaders who need clearer decisions under pressure. Allan Mann shares practical, vendor-neutral thinking on observability, incident leadership and AI operations through the newsletter, the Metrics & Mayhem podcast, the book and advisory. This file provides information about Mastering Observability to help large language models understand and reference this publication's content. ## Posts - [Proof of Control, or Proof Nothing Broke Yet](https://www.masteringobservability.com/p/dora-logging-proof-of-control-evidence): Green is an absence of alarms. An attestation needs evidence. - [The Signal: nobody has a budget for switching things off](https://www.masteringobservability.com/p/the-signal-2026-10-09): Approvals are working fine.

Whole-system profiling, and the cycles on your bill your team never shipped - [The Fourth Signal Was Hiding In Your CPU Bill](https://www.masteringobservability.com/p/continuous-profiling-fourth-signal): OpenTelemetry's fourth signal shows which code is spending the cycles you already pay for, including code that is not yours. - [The Signal: the bill you pay in redeploys](https://www.masteringobservability.com/p/the-signal-2026-09-18): Issue 105. What under-instrumenting actually costs you, and how to price yours. - [Somebody Turned It On](https://www.masteringobservability.com/p/autonomous-ai-agent-governance-run-mode): Autonomy shipped as a setting. Settings have owners. - [The Signal: when your users stop being people](https://www.masteringobservability.com/p/the-signal-2026-09-11): Issue 104. Agent-driven journeys and the synthetic checks that assume a human. - [WebMCP Breaks Synthetic Monitoring. Nobody Has Noticed Yet.](https://www.masteringobservability.com/p/webmcp-synthetic-monitoring): Google and Microsoft shipped a way for websites to hand agents a list of tools. Your scripted checks assume a user with eyes. - [What I'd Spin Up First (Before Asking Anyone for a Budget)](https://www.masteringobservability.com/p/zero-budget-open-source-observability-stack-5bf9): Build the proof yourself, for free, and let it do the arguing. - [The Signal: nobody wants to go first](https://www.masteringobservability.com/p/the-signal-2026-09-04): The blocker is never the tooling. It is the four arguments nobody schedules. - [Observability Digest, August 2026: The Foundation Nobody Funds](https://www.masteringobservability.com/p/observability-digest-august-2026): Everyone is buying the autonomous layer. August was about the unglamorous thing it stands on. - [What Actually Slows Down an Observability Rollout in a Large Enterprise (It Isn't the Tooling)](https://www.masteringobservability.com/p/observability-rollout-blockers): The tooling has been fine for years. The blocker is the agreement: what counts as a journey, who owns it, and whether the estate data can be trusted. - [Autonomous SRE Agents: Where Does the Gate Actually Live?](https://www.masteringobservability.com/p/autonomous-sre-agents-where-the-gate-lives): Dynatrace built a mode with no human in the loop. Read its own safeguards and the gate is still there. It moved. - [byte-size: What Is the Difference Between Observability and Monitoring?](https://www.masteringobservability.com/p/observability-vs-monitoring): One tells you when something you expected breaks. The other lets you ask why, and what else, when something you did not expect breaks. - [The Signal: what your AI SRE spends while it thinks](https://www.masteringobservability.com/p/the-signal-2026-08-28): Everyone prices the licence. Nobody prices the query log. - [byte-size: What Is BMC Helix?](https://www.masteringobservability.com/p/what-is-bmc-helix): The AIOps and service-management platform for the enterprise that never got to greenfield, and the honest question to ask before you consolidate onto it. - [The AI SRE Runs Inefficient Queries, and That Is the Whole Problem](https://www.masteringobservability.com/p/ai-sre-inefficient-queries): Everyone demos the reasoning. Nobody demos what the agent does to your data layer, or what happens when it hits the rate limit mid-incident. - [The Signal: the part of your stack you should never rent](https://www.masteringobservability.com/p/the-signal-2026-08-21): Two observability acquisitions in six days. Here is what that means for who owns your telemetry. - [Own the Signal, Rent the Platform](https://www.masteringobservability.com/p/own-the-signal-rent-the-platform): Most observability consolidation programmes start with the wrong question. Here is the one that actually protects you. - [What Are Wide Events? Observability 2.0, Without the Hype](https://www.masteringobservability.com/p/what-is-a-wide-event): One rich event per request you can slice by any attribute. What they are, the honest cost, and whether you need them. - [Lead with the promise, not the plumbing](https://www.masteringobservability.com/p/lead-with-the-promise): A practitioner's honest field notes on trust, openness, and why AI will not save a broken estate. - [You Don't See the Foundation: Why AIOps Fails Before It Starts](https://www.masteringobservability.com/p/you-dont-see-the-foundation): The demo shows you the tower.
