I'm trying to use Azure Monitor OpenTelemetry Exporter client library for Java to export all traces/spans from Spring Cloud Sleuth to Azure Monitor. This integration seems to only work with the newest version of Spring Cloud Sleuth after the recent dependency version updates.
However instead of using azureMonitorExporter.export(spanData) manually, I would like to export all traces/spans automatically for the whole application by just adding a configuration for Azure exporter. This could then easily be added to a new project.
I don't have much experience using Spring/Sleuth/OpenTelemetry, but AzureMonitorExporter implements SpanExporter, so I thought one option could be to create a configuration class that contains the following.
@Bean
public SpanExporter exporter() {
return new AzureMonitorExporterBuilder()
.instrumentationKey("{KEY}")
.buildExporter();
};
And then it could be used in the main class using:
@Autowired
SpanExporter exporter;
However I'm not sure if this is the right way or how to continue from here to actually get the exporter to start exporting traces/spans automatically to Azure monitor.
My pom.xml looks like this:
