MTTR and MTTD

When it comes to alerting and triage, mitigation is the name of the game.

MTTR – Mean Time to Resolve

MTTD – Mean Time to Detect

Reducing MTTD will reduce MTTR: Through robust alerting, you can uncover issues the moment they occur, allowing your teams the insights needed for a timely resolution.

MTTR and MTTD serve as KPIs that will help you to identify where bottlenecks exist in your response and triage. These will also indicate areas of improvement for your workflow and highlight the need for training. Several alert handling tools like PagerDuty are built to report on this.

Furthermore, alert configurations allow you to see when an alert clears. This will enable you to see the MTTR of any specific alert. In the example below, we see a five-minute MTTR.
