This configuration retains metrics for 30 days, balancing data availability and storage costs.

Alerting Features

Prometheus's Alert Manager is a powerful tool for setting up alerts based on specific metric thresholds. Configure alerts in your prometheus.yml file:

alerting:
  alertmanagers:
  - static_configs:
    - targets:
      - localhost:9093

Define alert rules using PromQL to ensure timely notifications for critical events:

groups:
- name: example
  rules:
  - alert: HighCPUUsage
    expr: process_cpu_seconds_total > 0.9
    for: 5m
    labels:
      severity: critical
    annotations:
      summary: "High CPU Usage detected"
