# Observability Deep Dive
## Modules
* [01-logback-mdc](01-logback-mdc) - Logback/MDC with executors, project reactor and coroutines
* [02-logback-brave](02-logback-brave) - Logback/MDC + OpenZipkin Brave with different flavors of concurrency
* [03-logback-otel](03-logback-otel) - Logback/MDC + OpenTelemetry, again with different flavors of concurrency
* [04-spring-classic-simple](04-spring-classic-simple) - Spring MVC examples
* [05-spring-coroutines-simple](05-spring-coroutines-simple) - Spring WebFlux with coroutines
* [06-service-a](06-service-a) - Service A is a simple service based on WebFlux/coroutines which calls Service B
* [06-service-b](06-service-b) - Service B is another service based on WebFlux/coroutines which gets called by Service A
## Local Infra
* [compose.yml](compose.yml) that runs **Grafana**, **Loki**, **Tempo** and **Prometheus**
* [localhost:3000](http://localhost:3000/) is how you access **Grafana**
## Open Issues
* Kotlin coroutine context propagation [openzipkin/brave/issues/820](https://github.com/openzipkin/brave/issues/820)
* Traceid and spanid wrong when using Kotlin Reactor Coroutines [micrometer-metrics/tracing/issues/174](https://github.com/micrometer-metrics/tracing/issues/174)
* Observation API does not support Baggage [micrometer-metrics/tracing/issues/455](https://github.com/micrometer-metrics/tracing/issues/455) and [micrometer-metrics/tracing/issues/563](https://github.com/micrometer-metrics/tracing/issues/563)
* Better support for working with Observation from Kotlin [micrometer-metrics/micrometer/issues/4754](https://github.com/micrometer-metrics/micrometer/issues/4754)
