Grafana
The dashboarding tool the entire industry agrees on. Beautiful, fast, and free.
What is Grafana, really?
Grafana is the visualization layer for almost every metrics + logs + traces stack. It plugs into 60+ data sources (Prometheus, Loki, Tempo, CloudWatch, Datadog, Elasticsearch, PostgreSQL, anything) and turns them into dashboards your engineers and execs both actually look at.
Grafana Labs has expanded the product into a full LGTM stack — Loki (logs), Grafana (dashboards), Tempo (traces), Mimir (long-term metrics). In 2026, knowing Grafana well = knowing the modern observability stack.
At Cloudadhar we teach Grafana for what matters in production: dashboards-as-code (provisioning via Git), templating + variables for reusable dashboards, alerting rules, and the LGTM stack for end-to-end observability.
What makes it special
- 60+ data source plugins — connect anything that holds data
- Beautiful, fast, dark-mode-first UI that engineers actually like
- Dashboards-as-code via JSON / Jsonnet / Grafonnet, versioned in Git
- Unified alerting (Grafana 9+) — one alerting UI across all data sources
- Free + open-source core; Grafana Cloud for managed hosting
When you should reach for it
- You use Prometheus (Grafana is the visualization half)
- You want one dashboard tool across multiple data sources
- You need to give business stakeholders self-service dashboards
- You're building a status / SRE dashboard for an on-call team
- You want to provision dashboards from Git (no manual UI clicks)
A real Grafana story from production
“We replaced a $14k/month Datadog bill with a self-hosted Prometheus + Grafana + Loki stack on a $400/month EKS workload. The migration took 2 engineers 6 weeks. The dashboards were arguably better than what we had on Datadog because we owned them and could shape them to our actual workflows. ROI in month 1.”

How to actually learn Grafana
- 1Install Grafana (or use the kube-prometheus-stack Helm chart)
- 2Connect Prometheus as a data source + build your first dashboard
- 3Use template variables ($cluster, $namespace, $app) for reusability
- 4Switch dashboards from UI-managed to JSON-provisioned (Git-tracked)
- 5Configure unified alerting + route to Slack / PagerDuty
- 6Add Loki for logs + Tempo for traces — full LGTM stack
