Without monitoring you find out about a problem when the site is already down. Prometheus and Grafana give you the full picture in real time — and alerts before something fails outright.
What gets monitored
- CPU, RAM, disk and network (node_exporter);
- web server, PHP-FPM, database;
- Redis, queues, containers;
- site availability and response time.
How it works
Prometheus scrapes metrics from the exporters and stores them, Grafana turns them into dashboards you can actually read, and Alertmanager sends notifications (Telegram, email) when a threshold is crossed.
The alerts that save you
- disk space running out;
- sustained high CPU or RAM;
- the site unreachable or slow;
- a service down or restarting.
Why it pays for itself
Early warning lets you act before the outage. And the dashboards show exactly what loads the server and when — which is where optimization starts.
Common questions
Can alerts go to Telegram?
Yes, and it is the most practical channel.
Will it load the server?
No — monitoring is lightweight, and can be moved to a separate host if needed.
Are dashboards included?
Yes, configured around your services.
