Eclipse MicroProfile OpenTracing
Payara Server 6.2023.3 provides MicroProfile OpenTracing 3.0
The Open Tracing API was created to allow easier tracing of the flow of a request in microservices environment across service boundaries.
The complete specification can be found on the Eclipse MicroProfile website.
Breaking changes introduced in MicroProfile OpenTracing 3.0 are listed in the official specification under Incompatible Changes
Support for MicroProfile Open Tracing is provided via compatibility layer for OpenTelemetry.
To achieve full compatibility in naming the spans with the spec a span convention needs to be configured as described in Span Naming Convention.
The Payara Platform implementation of the
io.opentracing.Tracer interface supports the following carriers:
The Payara Platform’s MicroProfile implementation supports tracing of requests that are handled by SOAP Web Services implemented via the JAX-WS API. Since JAX-WS is only supported on Payara Server Full Profile, this support is not covered on Payara Micro.
By default span names for JAX-RS endpoints follow recommendations set forth by OpenTelementry Semantic Conventions. In order to have span names follow naming conventions defined by MicroProfile OpenTelemetry, following MicropProfile Config property must be set for application or globally for the server or domain:
All valid values for the property are documented in OpenTelemetry Span Convention Settings
It is not possible to use other OpenTracing implementations in Payara Platform 6. It is however possible to deploy and configure other OpenTelemetry exporters (i. e. zipkin) into the server or ship them with application. Please consult OpenTelemetry Configuration.
