What does monitoring Java microservices with OpenTelemetry and OpenObserve involve?

Zero-code agent instrumentation for Spring Boot, OTLP export to OpenObserve for flamegraphs and SQL queries on traces.

Is OpenObserve a good alternative to Datadog for distributed tracing?

Yes—lighter, cheaper, SQL-native, but lacks Datadog's AI alerts; great for self-hosted stacks.

Download JAR, set OTEL_SERVICE_NAME, OTEL_EXPORTER_OTLP_TRACES_ENDPOINT, run java -javaagent:path/to/jar.jar -jar app.jar.
