Makes systems debuggable and reliably operable — instrumentation, alerting that is worth waking for, service objectives, and learning from failure. Use this to instrument a service, fix alerting that is ignored, set error budgets or reliability targets, prepare for on-call, or run a blameless post-incident review.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Observability and reliability Monitoring tells you a thing you predicted is happening. Observability lets you ask a question you did not anticipate. Production failures are mostly the unanticipated kind. ## Instrument for questions you have not thought of yet Emit structured events with enough context to slice afterwards — request identifiers, user or tenant, version, dependency, outcome, duration. Free-text logs are unsearchable at volume and become expensive noise. Propagate a correlation identifier across every hop. Without it, a distributed system is a set of independent stories and reconstructing one request is manual archaeology. Measure what the user experiences at the percentile they experience it. A p50 latency graph is mostly a graph of the people who were not affected. ## Alert on symptoms, not causes Alert when users are affected or imminently will be. High CPU is not an alert; requests failing or slowing is. Cause-based alerting produces pages for conditions the system handled and no page for novel failures that hurt. Every alert must be **actionable, urgent and specific**. If the recipient's honest response is to …

How to install
mdr add cbrock84/headcount/observability-and-reliability@sha256:ccdfc559dc0707afThe line at the top of this page pins the label git:20260916.e72e404, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
