A runbook is a step-by-step procedure for handling a specific situation. When a problem occurs, the runbook tells you exactly what to do.
What makes a good runbook:
- Specific: Addresses one scenario
- Sequential: Numbered steps in order
- Actionable: Each step is concrete
- Complete: Includes commands and expected output
- Tested: Someone has followed these steps successfully
Example scenarios: Primary internet link down, core switch failover, DNS server not responding, VPN tunnel down.
Runbooks turn expertise into procedure that anyone can follow at AM.
