Why Prometheus & Grafana are the best Monitoring Duo

👋 Hi,

Welcome to the first edition of my newsletter! 🎉

In this issue, you’ll learn:
✅ Why Prometheus & Grafana are so popular
✅ What problems they solve
✅ When they (might not) be the right choice

Why Prometheus & Grafana?

The IT landscape is getting more complex: More containers, more services, more data. Traditional monitoring tools like Nagios or Zabbix often struggle to keep up. That’s where Prometheus comes in:

✅ Efficient metric collection – Prometheus stores time-series data efficiently and scales well.
✅ Flexible querying with PromQL – Powerful analysis using its query language.
✅ Easy integrations – Hundreds of exporters available for different applications (e.g., Docker, Kubernetes, Linux servers).
✅ Seamless visualization with Grafana – Dashboards, alerts & more in a single UI.

🚀 What Prometheus Can't Do

Of course, Prometheus isn’t perfect. If you need...
⚠ Log monitoring → Use Loki
⚠ Trace analysis → Use Jaeger or OpenTelemetry
⚠ Stateful alerting → Consider Thanos

Still, Prometheus remains the top choice for metric-based monitoring!

🎯 What’s Next?

In the next issue, I’ll show you how to set up Prometheus in 10 minutes – including your first metric query!
