When you’ve instrumented your services to send errors to Rollbar, Rollbar accesses the Lightstep API to create a Snapshot of that error in the context of the associated request through your system. That data is persisted so you can view it in Lightstep Observability at any time, using the Lightstep Trace button.

Because that Snapshot is persisted, Lightstep Observability has a full record of the request, allowing you to start investigating the cause. A pre-configured link back into Rollbar let’s you resolve the error seamlessly.
