Opentelemetry instrumentation

[jomcgi]

Would it be useful to flag this instrumentation package for asyncclick users?

Contrib repo with source code:
https://github.com/open-telemetry/opentelemetry-python-contrib/tree/main/instrumentation/opentelemetry-instrumentation-asyncclick

PyPI:
https://pypi.org/project/opentelemetry-instrumentation-asyncclick/

pip install opentelemetry-instrumentation-asyncclick

Example usage:

import asyncio
import asyncclick
from opentelemetry.instrumentation.asyncclick import AsyncClickInstrumentor

AsyncClickInstrumentor().instrument()

@asyncclick.command()
async def hello():
    asyncclick.echo(f'Hello world!')

if __name__ == "__main__":
    asyncio.run(hello())

When this is configured with an exporter / receiver you get spans for each command with details like:

    span_attributes = {
        PROCESS_COMMAND_ARGS: sys.argv,
        PROCESS_EXECUTABLE_NAME: sys.argv[0],
        PROCESS_EXIT_CODE: 0,
        PROCESS_PID: os.getpid(),
    }

This can be useful for projects where you want to measure the latency of commands.
