What do I need to get `./otelcol running, in your previous videos I have not seen you install any specific tool to be able to call this command successfully, Did I miss something?

[vivekshukla]

My response somehow got deleted, but this video I am having trouble following, for example - starting from using the docker command to run the jaeger, so I used previous video to run the jaeger then even after jumping through hoops I could never get past the issue when I run `python app.py` command. I receive Transient error StatusCode.UNAVAILABLE encountered while exporting traces to 127.0.0.1:6004. error. Suggestion is appreciated.

Hi, thanks for the video. Could you explain the difference between OpenTelemetry Collector and jaeger-collector?

[AGunzOw]

did you confuse http vs grpc with tcp vs websocket? I thought grpc is where you define the schema for compact serialization and unmarshaling

[vivekshukla]

Thank you so much. How can I start the collector up? Your code in github doesn't have `otelcol` file - I would appreciate your help.

Any specific reason to use 6004 port instead of 4317. ?

[vivekshukla]

Running this `docker run -p 16686:16686 -p 4317:4317 225` produces error stating Unable to find image `225:latest` locally. I was so looking forward to getting this done, using your tutorials, but I may end up moving on to someone else's. :(
