Prometheus

App in the BluixApps catalog

What it is

Prometheus is the CNCF metrics + alerting system — pull-based scraping, time-series database, PromQL query language. The de-facto standard for cloud-native monitoring; if you're running containers or Kubernetes, you're almost certainly using Prometheus or wishing you were.

For SRE / DevOps teams who want metrics done right — not just collected but queryable, alertable, and graphable — Prometheus is the answer.

What it's for

  • Infrastructure metrics — CPU, RAM, disk, network from node_exporter
  • Application metrics — request rate, error rate, latency from instrumented apps
  • Custom metrics — anything that emits Prometheus-format metrics
  • Alerting — PromQL-based alert rules sent to Alertmanager
  • Capacity planning — historical metrics for sizing decisions

Who it's for

  • SRE / DevOps teams running container or Kubernetes infrastructure
  • Platform engineers building observability stacks
  • Application developers instrumenting code for production visibility
  • Engineering managers wanting KPI dashboards from real metrics
  • Hosting providers offering customer-facing metrics dashboards

Why teams pick Prometheus over alternatives

  • Apache 2.0 — fully open, CNCF-stewarded
  • Pull model — Prometheus pulls from targets; cleaner than push-based
  • PromQL — most expressive metrics query language
  • Vast exporter ecosystem — thousands of exporters for every service
  • Standard format — Prometheus exposition format is the de-facto standard
  • Strong Grafana integration — first-class dashboard tool

Integrations

  • Exporters — node, mysqld, postgres, redis, blackbox, snmp, hundreds more
  • Alertmanager — alert routing to Slack, PagerDuty, email, custom
  • Visualization — Grafana (primary), built-in expression browser
  • Long-term storage — Thanos, Cortex, Mimir, VictoriaMetrics
  • Service discovery — Kubernetes, Consul, DNS, file-based
  • Recording rules — pre-compute expensive queries for dashboards
  • Federation — hierarchical Prometheus setups for multi-tier orgs

Notable users & community

  • 56k+ GitHub stars
  • CNCF graduated project (with Kubernetes, Envoy)
  • Used by SoundCloud (origin), DigitalOcean, Cloudflare, JP Morgan
  • Standard tool in every cloud-native engineering org
  • KubeCon / PromCon conferences annually

Tips & operations

  • Retention vs disk — 15-day default; longer needs remote write to Thanos/Cortex
  • Cardinality is the killer — high-cardinality labels (user IDs, trace IDs) cause issues
  • Recording rules for slow queries — pre-compute expensive panel queries
  • Alert routing via Alertmanager — Prometheus generates alerts, Alertmanager routes them
  • Persistent volume — TSDB lives here; size for retention needs
  • Federation for scale — global Prometheus aggregates from regional Prometheuses
