Monitoring Stack Overview: Prometheus, Grafana, Loki, and Alertmanager¶
This section explains a practical monitoring stack built with Prometheus, Grafana, Alertmanager, Loki, Promtail, Blackbox Exporter, and supporting exporters.
What This Stack Covers¶
- Metrics with Prometheus
- Dashboards with Grafana
- Alert routing with Alertmanager
- Logs with Loki and Promtail
- Synthetic checks with Blackbox Exporter
Why This Setup Is Useful¶
Many examples stop at metrics only. This stack is more practical because it combines the main observability layers in one place:
- Metrics
- Logs
- Alerts
- Endpoint reachability checks
That makes it a solid learning setup for DevOps and SRE work.
Recommended Flow¶
- Read the stack overview.
- Start the lab and verify the services.
- Review Prometheus and Grafana.
- Add alerting, logging, and blackbox checks.
- Use the troubleshooting page when a service does not behave as expected.
