Python Wrapper for OpenTelemetry written to scratch the itch of needing to use the same / similar code across several Google Cloud Functions and wanting to abstract away from tracing / logging so I can mix and match the two.
Some of these cloud functions are invoked via HTTP, others from Pub/Sub messages.
For Pub/Sub I have jury-rigged persisting the state of a Span to propagate between processes. To ensure that a trace that goes from function to function via pub/sub remains contiguous.
I'm sure there is a better way of doing this but this is good enough for my purposes and by putting my solution out in the wild I'm hoping to get feedback to help improve it.
For http I have used the W3C Trace Context Level1 Recommendation from 6 February 2020. I rolled my own here as I didn't find an existing Python implementation. Again if I have missed something and someone would like to put me right that would be great!
pip install barium-meal
The tests are the best guide to usage. In the interests of keeping things DRY please take a look there.
In a new virtual environment:
