We've been using Sleuth at LaunchDarkly as a single pane of glass for all changes going out into production. The addition of DORA metrics is exciting-- as an engineering leader, Accelerate (https://itrevolution.com/accelerate-book/) is one of the few books I've read where the practices described meet reality. Having a tool track those metrics is a welcome addition.
One thing I'm curious about is Sleuth's approach to the "garbage in, garbage out" problem-- if I'm tracking (e.g.) MTTR, I've found that our teams aren't always perfect about tracking the start / end times of an incident. If the data's incorrect, can I modify it in manually?
