Use when Prometheus on Kubernetes does not collect or alert as expected: a ServiceMonitor or PodMonitor whose targets never appear, targets that are down ("server returned HTTP status 404 Not Found", "connection refused", "context deadline exceeded"), a PrometheusRule that does not load or alerts that do not fire or reach Alertmanager, a Prometheus or Alertmanager custom resource that is not Available, "InvalidConfiguration" events from the Prometheus Operator, or Prometheus pods that are…
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
# Prometheus troubleshooting Find out why Prometheus does not scrape a target, does not load a rule, or does not alert, and propose a fix. **Read first, ask before changing.** Run the investigation commands freely. Run a command under an "Ask first" line only after the user approves that exact command; if your credentials do not allow it, give it to the user to run. Never run a "Proposed fix"; hand it to the user. With the **Prometheus Operator**, a `Prometheus` custom resource selects **ServiceMonitors**, **PodMonitors**, **Probes**, **ScrapeConfigs** and **PrometheusRules** by label and namespace, and the operator turns them into Prometheus' configuration. A ServiceMonitor selects Services by label and names one of their ports. Something can go wrong at each step: the selection, the Service, the port, the scrape itself. The commands use placeholders: `monitoring` (where Prometheus runs), `my-prometheus` (the Prometheus resource), `my-namespace`, `my-app` (the ServiceMonitor and its Service) and `my-rules`. Replace them with the real names. Prometheus' HTTP API is reached through the API server's service proxy on the governing Service …

How to install
mdr add k8s-servant/k8s-skills/k8s-prometheus-troubleshooting@sha256:a717e200c1e473bdThe line at the top of this page pins the label git:20261024.b2bfbd1, 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.
