How can I integrate Alertmanager with my monitoring system?

To integrate Alertmanager, you'll need to configure it to receive alerts from your monitoring system. What system are you using?

I'm using Prometheus for monitoring.

Great! You can configure Prometheus to send alerts to Alertmanager by defining alerting rules in your Prometheus configuration file.

Can you show me an example of an alerting rule?

Sure! Here's a simple example:

groups:
- name: example
  rules:
  - alert: HighCPUUsage
    expr: sum(rate(cpu_usage_seconds_total[5m])) by (instance) > 0.9
    for: 5m
    labels:
      severity: critical
    annotations:
      summary: "High CPU usage detected on {{ $labels.instance }}"

This rule triggers an alert if CPU usage exceeds 90% for 5 minutes.
