Unable to send custom metrics using otel Java Agent.

[rahul-narkhede]

I have a java servlet application running via otel agent in tomcat server. I can see the traces and default metrics created by application coming into my collector and eventually into datadog.

However, I wanted to add some custom metric Histograms. So, I created the meter object using GlobalOpenTelemetry

Meter meter = GlobalOpenTelemetry.getMeter("")
LongHistogram myhistogram =  meter.histogramBuilder(...)
....

When I set the -Dotel.metrics.exporter=otlp,logging , I can see the metric value logged on my console, but nothing shows up on collector or datadog.

Any help in this matter is appreciated.

do you have the otlp exporter added as a dependency?

implementation("io.opentelemetry:opentelemetry-exporter-otlp")
