Incident Replay reconstructs past incidents as an interactive, visual playback. Step through the exact sequence of events, from first alert to final resolution, with synchronized metrics, logs, and service map changes at each moment. Use it for postmortem reviews, on-call training, and building shared understanding across your team.
Incident Replay works like a DVR for your infrastructure. Select any resolved incident and hit play. The timeline scrubber advances through each event, alert fired, engineer acknowledged, deployment rolled back, service recovered, with synchronized dashboards showing the exact state of your metrics, logs, and service map at that moment. Pause at any point to explore the data in depth, or fast-forward through quiet periods to focus on the critical moments.
During replay, all signals are time-locked to the playback position. The service map highlights affected nodes as the incident propagates. Metric charts animate in real time, showing the latency spike, error rate increase, or throughput drop as it happened. Log panels scroll to the exact lines that were relevant at that moment. Your team sees the incident the way it actually unfolded, not through a static postmortem summary.
Incident Replay transforms your incident history into a training library. New team members can replay significant past incidents to understand how experienced engineers diagnosed and resolved them. Annotated replays with commentary from senior responders become reusable training modules. Run "game day" exercises where new on-call engineers replay a real SEV-1 and practice their response, without any risk to production systems.
Replay past incidents visually to improve postmortems, train on-call engineers, and build organizational resilience.
