otel-exporter appends :443 after url

[HugoVG]

Brief summary

I've been wanting to send the results of my k6 load test to my otel collector but it seems k6 keeps appending :443 after my URL's (external)

k6 version

0.53

OS

Docker

Docker version and image (if applicable)

grafana/k6:latest

Steps to reproduce the problem

• Docker with K6
• Docker with app
• LGTM or other Otel Collector somewhere outside docker k6: environment:
  • K6_OTEL_METRICPREFIX=k6
  • K6_OTEL_EXPORTER_TYPE=grpc
  • K6_OTEL_GRPC_EXPORTER_INSECURE=true
  • K6_OTEL_GRPC_EXPORTER_ENDPOINT=http://ExternaOtelCollector:4317/ Command: k6 run -o experimental-opentelemetry ~/LoadTest.js

Expected behaviour

it doesn't append the :443 and resolves like the other services to the specified otel endpoint

Actual behaviour

¡Keep in mind the IP has been modified to 00.000 at the end, this is running within my local network, the collector is running collection for LGTM and works perfectly fine even from within the other services inside the docker!

Command: k6 run -o experimental-opentelemetry ~/LoadTest.js Environment:

• K6_OTEL_METRICPREFIX=k6
• K6_OTEL_EXPORTER_TYPE=grpc
• K6_OTEL_GRPC_EXPORTER_INSECURE=true
• K6_OTEL_GRPC_EXPORTER_ENDPOINT=http://10.10.00.000:4317/ (Keep in mind I also tried without '/')

at the end of the run: 2024-11-14 13:51:14 time="2024-11-14T12:51:14Z" level=info msg="2024/11/14 12:51:14 failed to upload metrics: failed to exit idle mode: invalid target address http://10.10.00.000:4317/, error info: address http://10.10.00.000:4317/:443: too many colons in address" ^it adds :443 which breaks the call

Remove https:// from K6_OTEL_GRPC_EXPORTER_ENDPOINT
