The OpenTelemetry Javaagent buildpack framework will cause an application to be automatically instrumented with the OpenTelemetry Javaagent Instrumentation.

Data will be sent directly to the OpenTelemetry Collector.

Tags are printed to standard output by the buildpack detect script

Users are currently expected to create-user-provided-service (cups) of the collector and bind it to their application. The service MUST contain the string otel-collector.

For example, to create a service named otel-collector that represents an environment named cf-demo, you could use the following commands:

$ cf cups otel-collector -p '{"otel.exporter.otlp.endpoint" : "https://my-collector-endpoint", "otel.exporter.otlp.headers" : "authorization=Basic SOMEBAS64STRING","otel.exporter.otlp.protocol" : "grpc", "otel.traces.exporter" : "otlp", "otel.metrics.exporter" : "otlp", "otel.resource.attributes": "deployment.environment=cf-demo"}'
$ cf bind-service myApp otel-collector
$ cf restage myApp

Additional configuration options for the Agent can be found here

Most users should skip this and simply use the latest version of the agent available (the default). To override the default and choose a specific version, you can use the JBP_CONFIG_* mechanism and set the JBP_CONFIG_OPENTELEMETRY_JAVAAGENT environment variable for your application.

For example, to use version 1.27.0 of the OpenTelemetry Javaagent Instrumentation, you could run:

$ cf set-env testapp JBP_CONFIG_OPENTELEMETRY_JAVAAGENT '{version: 1.27.0}'
