In my previous job, I've integrated OpenTracing and OpenTelemetry into our microservices. You need to do this in microservice infrastructures to be able to debug and investigate service calls. We first used Jaeger for tracing calls across service boundaries, and then migrated to Instana.

Instana is a wholistic solution and does a pretty good job merging and displaying the collected metrics, logs, and traces. I did prefer Jaeger for tracing simple service calls because it isn't as complex as Instana from a developer perspective, but if you need a deep insight into your running servers, operating systems, runtimes, containers, and applications and how they interact with each other, Instana is really powerful.
