Overview
MTTD measures the effectiveness of a system's monitoring and alerting. Reducing MTTD is the first step in reducing the overall impact of an incident.
Calculation
MTTD = (Total time between incident start and detection) / (Number of incidents)
How to Improve MTTD
- Comprehensive Monitoring: Covering all layers of the stack.
- Fine-tuned Alerting: Ensuring alerts are triggered promptly but accurately.
- Anomaly Detection: Using AI/ML to identify unusual patterns that might indicate a problem.
