OpenTelemetry Monitoring: No Telemetry Data Exported

Bug Description claude code OTEL monitor not working. I have set the env configuration according to the doc. However, my observability backend does not receive any data from claude. Enable debug or run command /status does not give any feedback.

Environment Info

• Platform: linux
• Terminal: Tabby
• Version: 1.0.16
• Feedback ID: 93ed3bb8-bf6e-4338-a4db-781daaba6c04

Errors

[]

When was this added?

I was able to get it working now. The issue lie in the problem with my config for claude in $HOME/.claude/settings.json.

Instead of

"OTEL_EXPORTER_OTLP_PROTOCOL": "http",

It should be

"OTEL_EXPORTER_OTLP_PROTOCOL": "http/json", # or "http/protobuf"

Beside, there was problem with my observability set up. Otel-collector did not push data to Prometheus properly. Both of the silent errors and very hard to tell which part is wrong. Whoever come to this thread later, I recommend using some well packages observability stack like signoz. It work out of the box. It took me a day to try export with different method and console to debug the problem. Happy spending for AI :)

Hell yeah Tran! Would love to see what metrics are available and how to collect! Would make for an awesome post, or just reply to this issue.

Already DM'd you but I for one would be interested.

Glad you figured it out!

i have otel working with prometheus, but the actual traces/spans are empty:

Trace ID: 
Span ID: 
Flags: 0

is this expected? i'm surprised that there are no examples of tracing claude code...

---

EDIT: i think i just didn't have export OTEL_TRACES_EXPORTER=otlp...now i seem to be able to find the content.

either way - as general feedback for the claude code team - i'm sure there are thousands of people that would benefit from a basic tutorial on how to trace claude code. even the claude docs helper bot doesn't know how to do it. this page is helpful but basically just a giant list: https://docs.anthropic.com/en/docs/claude-code/monitoring-usage

---

EDIT #2 : after much futzing around, this is the missing piece (the actual claude API response!) => https://github.com/anthropics/claude-code/issues/2090
