Monitoring Stack Setup: Prometheus, Grafana, and Alertmanager
Published: 2026-02-20 | Section: Reliability & Operations | Author: Amirreza Rezaie
I set up a monitoring stack to observe Goalixa at three levels:
- Service level
- OS/node level
- Cluster level
The core stack is:
- Prometheus for metrics collection and storage
- Grafana for dashboards and visualization
- Alertmanager for alert routing and notifications
Monitoring Goals
- Expose metrics from each service
- Track health and performance for nodes and cluster
- Detect failures faster with useful alerts
- Reduce incident response time
Monitoring Flow
Alerting Strategy
I want to configure useful alerts for each service and node, such as:
- Service down / high error rate
- High latency on critical endpoints
- Pod restart spikes
- Node CPU/memory/disk pressure
- Cluster resource saturation
Next Improvement Steps
- Finalize per-service SLI/SLO-aligned alerts
- Tune alert thresholds to reduce noise
- Add dashboard views for incident triage
- Define severity levels and escalation policy
