MTTR
MTTR (Mean Time To Repair) is a core metric in IT operations for measuring system reliability and operational efficiency. It represents the average time elapsed from the occurrence of a failure to full recovery, and is commonly used alongside MTBF (Mean Time Between Failures) and MTTD (Mean Time To Detect).
Core Facts
Timeline (last 90 days)
MTTR (mean time to repair) is a metric measuring the time elapsed from when a vulnerability is confirmed to when a patch goes live, and is also one of the core metrics of security operations efficiency.
MTTR refers to the average time required from the occurrence of a failure to service recovery.
MTTR (mean time to recovery) is a core metric for measuring the efficiency of alert handling processes and is one of the most frequently cited KPIs in the SRE field.
MTTR (Mean/Median Time To Repair or Resolve) usually refers to the complete elapsed time from when a failure is recorded to when service is restored.
The industrial field commonly uses MTBF (mean time between failures) and MTTR (mean time to repair) to measure system reliability, and reduces the impact of single points of failure through strategies such as redundancy design, anomaly detection, and graceful degradation.
P1 usually refers to a severe failure that affects core functionality, impacts a large number of users, or causes business interruption; most vendors set the recovery target for P1 at the hour level.
Watchdog typically sends probe requests to the target at fixed intervals (such as HTTP status codes, port connectivity, response latency), and triggers an alert or recovery action when the number of consecutive probe failures exceeds a threshold.
Correlating metrics, logs, and traces is the core capability that distinguishes modern observability platforms from traditional monitoring tools, and is also the key to reducing MTTR.
Combining LLMs with runbooks can significantly compress mean time to recovery (MTTR) for failures with fixed patterns and clear boundaries, such as imminent certificate expiration or database connection pool exhaustion.
Under an automated diagnostics framework, the reduction in MTTD is often more significant than the reduction in MTTR
