Monitoring and alerting
Knowing something broke before your customer calls — and only being woken when it actually matters.
Most monitoring fails in one of two ways: it measures nothing of value, or it cries wolf so often that nobody looks any more. Both are as bad as having none.
I set up what actually says something about your service:
- Availability and response time of the application, not just ping
- Disk, memory, CPU and I/O with thresholds that match your load
- Certificates, domains and expiring keys
- Backup results — a failed backup is an incident
- Alerting through the channel you actually watch
Usually built on Prometheus with Grafana, or Zabbix where that fits better with what is already in place.
