Ask HN: Distributed tracing service with critical path analysis?
The Dapper paper mentions &quot;An engineer working on long tail latency debugging built a small library which infers hierarchical critical paths from DAPI Trace objects. These critical path structures were then used to diagnose problems and prioritize prospective performance improvements for universal
search.&quot;<p>Do any of the distributed tracing services (e.g. Datadog APM, AWS X-Ray) offer this? I don&#x27;t see any services which tout this functionality.
