OTEL not exporting to external server

Hey team, I've been reading docs and trying different configurations. But I can't seem to get my local OTEL logs and traces on my remote LGTM stack. The project is fairly simple, it's a Deno Fresh (1) setup. With some API endpoints which I want to see the logs for. Using Deno 2.4.1 Environment (not in .env, but actual runtime)

OTEL_DENO=true
OTEL_EXPORTER_OTLP_ENDPOINT=http://172.16.0.7:4318
OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf

OTEL_DENO=true
OTEL_EXPORTER_OTLP_ENDPOINT=http://172.16.0.7:4318
OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf

The LGTM is from the default docker example in the docs. I can reach Grafana on port 3000 just fine. Any clues to what I'm doing wrong?

Are you passing --unstable-otel to Deno?

Not after updating to 2.4.1 Let me try, just to be sure

marvinh.•2mo ago

ah right, I was just looking at our docs and it mentioned that. Might be that this page hasn't been updated yet

You're all out there developing faster than you can write docs 😄 No change though Would be helpful if I could set the DEBUG variable to something so I get OTEL info in my terminal. Like DEBUG=OTEL:*

marvinh.•2mo ago

There is DENO_LOG=debug which dumps a bunch of internal things

Oh, that's good info. Sadly no debugging on OTEL. I've upgraded the Docker image to the latest version. Also did some debugging on the LGTM stack as I started to suspect it might simply not accept any data. But I've succesfully send it a message from CURL

i've been doing a bit of Deno/OTEL work recently, and discovered this tool, which is quite good to run locally to receive and view OTEL msgs directly from Deno whilst debugging, without the faff of the full scale monitoring apps... https://github.com/ymtdzzz/otel-tui

I’ll give that a try, thanks!
