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.

// What it is

A closer look.

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.

// Use cases

What it's for.

Concrete scenarios where teams pick Prometheus over the SaaS alternative.

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

Built for these teams.

If your team profile matches one of these, Prometheus is a strong fit out of the box.

Profile A

SRE / DevOps teams

running container or Kubernetes infrastructure

Profile B

Platform engineers

building observability stacks

Profile C

Application developers

instrumenting code for production visibility

Profile D

Engineering managers

wanting KPI dashboards from real metrics

Profile E

Hosting providers

offering customer-facing metrics dashboards

// Differentiators

Why teams pick Prometheus.

When evaluating self-hosted options for this category, here are the dimensions on which Prometheus consistently lands above the 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

// Tips & operations

Run it properly.

Operational guidance from running this in production — what to do before you scale, what to lock down, what surprises people.

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