Full skill instructions

prometheus

Use this skill for Prometheus + Alertmanager + Grafana 监控体系建设与运维。

Defaults / assumptions to confirm

Deployment: kube-prometheus-stack / standalone
Alert routing: Alertmanager receivers (Slack/WeCom/PagerDuty)
Metrics source: app exporters, node-exporter, kube-state-metrics
Naming conventions and label cardinality constraints

Workflow

Understand what to measure

Identify golden signals: latency, traffic, errors, saturation.
Map business KPIs and critical user journeys to technical indicators.

Instrumentation guidance

Prefer stable metric names and bounded label sets.
Avoid high-cardinality labels (user_id, request_id, raw URLs).
Use histograms for latency (p50/p95/p99 via histogram_quantile).

Scraping configuration

Confirm scrape targets (ServiceMonitor/PodMonitor or static configs).
Ensure relabeling rules are correct; set scrape intervals/timeouts appropriately.

Alert design (practical)

Alerts should be actionable and low-noise.
Use multi-window multi-burn-rate for SLO alerts where applicable.
Add for: to avoid flapping; include runbook links in annotations.

Dashboarding

Provide per-service dashboards: RPS, p95 latency, error rate, resource usage.
Add drill-down: by route group, instance, and dependency.

Troubleshooting checklist

Missing metrics: target down, wrong labels, scrape failures, RBAC/network issues.
Wrong metrics: unit mismatch, counter resets, histogram buckets incorrect.
High load: cardinality explosion, too frequent scrapes, heavy queries.

Outputs

Metrics plan: required metrics, labels, and thresholds.
Alert rules: PromQL + severity + routing + runbook.
Grafana dashboard layout and key panels.
Runbook: symptom → checks → mitigation → rollback.
