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.
