aws-xray-sdk on a lambda function

Question

I see that I can enable x-ray tracing on my lambda function just by checking a checkbox (or setting Tracing: Active if using SAM). That adds a high level logging.

If I want more detailed logging, my understanding is that I need to add:

from aws_xray_sdk.core import xray_recorder
from aws_xray_sdk.core import patch_all
patch_all()

however, the xry sdk is not part of lambda. Clearly one of the solutions is to install it with pip install aws-xray-sdk -t . but that will add 42Mb to the function's code.

Is there an alternative solution? thanks

What is your original bundle size before adding X-Ray SDK? If this single module design produces a big overhead to your function code, you can open an issue at the SDK repo https://github.com/aws/aws-xray-sdk-python with your use case so it can be properly addressed. — haotian465, Apr 05 '19 at 00:03

Unfortunately the X-Ray Python SDK is written as a single package, and there are no current work arounds to reduce the payload size.

This is only true for Python right? The other runtimes like nodejs and java are included as part of the lambda? Where can I read more on this? I couldn't find it from the aws docs – pelican Jun 24 '19 at 13:34

You can use lambda layers to bake the X-Ray SDK to your runtime to keep your function code small. See more details on lambda layers https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html. Please let me know if you have extra concerns on using layers.

that is what I ended up doing - I was just hoping that there was an easier way, Thanks – Diego Apr 05 '19 at 12:33
