Thank you @prathamesh-sonpatki

This looks great. added few small nits.

I tried to open an account in last9 to test the integration, but seems the OpenTelemetry receiver should be enabled on your side:

The OpenTelemetry endpoint is not enabled. Please request to proceed.

Thanks, @blumamir. I have taken the review comments. You will see the OpenTelemetry endpoint available in your Last9 account 👍🏽

Let me know if any other change is required.

Thanks again @prathamesh-sonpatki

Tried the integration locally from your branch. needed to apply few fixes to make it work (added as PR comments).

After those fixes, I can see data in your system.

Question: the api endpoint: https://otlp.last9.io:443 - will it always be this constant value for all users? if so, perhaps we can remove it from the config or make it optional to reduce friction and required configuration?

2 issues I detected in Last9 while testing:

• on boarding screen, if I click the copy button for Auth Header it copies the value of password which was a bit difficult to figure out.
• when searching traces in grafana with the tempo data source, every trace I click results in this message: "failed to get trace with id: 2f103f9e25b3b8ab1c7d66bd2325bbc8 Status: 404 Not Found Body: {"error":"trace not found"}"

Thanks again for adding this integration

@blumamir Thanks! I have taken care of the feedback :)

1. Regarding the URL otlp.last9.io, it is not the same for everyone; it depends on the region selected when onboarding, so we should keep it.
2. The 404 error - my bad, I had missed a config change during deployment; it should be fixed now!
3. Thanks for feedback on onboarding, we will work on improving it

Thanks!

@prathamesh-sonpatki looks great.

Few more issues I spotted in last 9 while testing:

• When I search traces in grafana with tempo data source - I can see 4 services, but there suppose to be 5. the memebership service is missing. sent to to jaeger to verify and I can see this service in jaeger but not last9:

• When viewing traces in the "Traces" page, I can only see one service (frontent) which is the entry point, but all other services are missing:
