hey, we have a user storage SPI we want to instrument with open telemetry, are there some guidelines on how to do it? |

@KyriosGN0 Hi! It is possible to create your custom spans via the Tracing SPI available in Keycloak (note it is an internal SPI and things may change). Please look at the TracingProvider, where you can find comprehensive information on how to use it. The best way is to use TracingProvider.trace(). You can also check how it is done in Keycloak codebase and do the same in your extension 👋 |

Thank you for the example, @mabartos ! Is it by retrieving an already existing singleton, something like this? Or by initializing an OpenTelemetry instance and configuring everything from scratch, something like this: The 2nd approach brings error for duplicate references to opentelemetry libraries. Thanks! |

@keren-tevet Keycloak fetches the OpenTelemetry instance via Arc CDI from Quarkus under the hood. You can retrieve the OTel Tracer as var tracingProvider = session.getProvider(TracingProvider.class);
// 1. wrap your invocation and create a span
tracingProvider.trace("MyClass", "doSomething", span -> {
// this block will be traced
doSomething();
});
// 2. get the OTel Tracer instance
Tracer tracer = tracingProvider.getTracer("tracer", "version"); |

Thanks again! This is very straight forward and much simpler than what I've tried. 2 other questions I have -
