Learn how to define SLIs, error budget, PromQL, and promtool tests for burn-rate alerts that catch fast incidents without turning every short spike into a broken on-call shift.

Define a label contract, create RED/USE recording rules, validate cardinality with promtool, and roll out Kubernetes API dashboards without turning every route into a series factory.

Find which kube-state-metrics families inflate Prometheus, prune volatile labels with allowlists, and validate alerts and dashboards before rolling the change out.
Created: June 24, 2026 · Published: June 24, 2026
A practical guide to turning burn-rate alerts into actionable signals: clear SLOs, multiple windows, PSI as context, promtool tests, and gradual rollout.

An actionable guide for detecting Kubernetes API WATCH/LIST pressure by combining API server, etcd, Prometheus, and client validation before timeouts spread.
Created: June 12, 2026 · Published: June 12, 2026
A practical guide to adding PSI to Kubernetes API dashboards, correlating CPU/memory/IO pressure with SLIs, and designing alerts that page only on real impact.

kube-state-metrics can turn Kubernetes state into a storm of series, labels, and dashboards that look precise but do not help. This guide shows how to measure the noise, remove unstable labels, keep critical signals, and validate Prometheus before touching production.

A practical guide to diagnosing Kubernetes container memory with Prometheus and Grafana without confusing usage, working set, RSS, or reclaimable page cache.

A practical guide to traffic, latency, errors, and saturation for Kubernetes APIs without filling Prometheus with useless series or breaking alerts.
Created: April 22, 2026 · Published: April 22, 2026
Recent Prometheus, OpenTelemetry Collector, Loki, and Alloy releases all point to the same uncomfortable truth: alerts wired straight to raw metrics and fragile labels become noisy or broken very easily. This guide shows how to anchor burn-rate alerts on stable recording rules, validate them with promtool, and roll them out without turning every short spike into a fake emergency.

kube-state-metrics is still valuable, but in 2026 it exposes more surface area, more stable metrics, and recent defaults such as EndpointSlices. If your dashboards filled up with irrelevant series, fragile joins, or duplicated states, this guide shows how to reduce noise at the source, fix your queries, and validate that the cleanup does not break alerts or troubleshooting.

A technical, actionable guide to map golden signals to Prometheus metrics and PromQL, build Grafana panels, create alerts and follow a reproducible troubleshooting flow for Kubernetes APIs without adding unnecessary agents.
