I want to trace calls to the Python AWS SDK (boto3) by using the X-Ray SDK. According to the X-Ray docs, I have to patch boto3. Then X-Ray will automatically create sub-segments, so I only have to surround the AWS SDK calls inside a segment. Here is my code:
import boto3
from aws_xray_sdk.core import xray_recorder, patch_all
patch_all()
codecommit = boto3.client("codecommit")
# begin a segment
xray_recorder.begin_segment("Main")
# create a CodeCommit repository named "myrepo1"
codecommit.create_repository(repositoryName="myrepo1")
# end a segment
xray_recorder.end_segment("Main")
First I start the X-Ray daemon, then I run the script. However, the daemon returns the following error:
2018-07-27T15:33:01+08:00 [Info] Successfully sent batch of 1 segments (0.146 seconds)

Further, when I view X-Ray on AWS Console, nothing appears on the service graphs nor traces.
Searching the web, I couldn't find any instances of this error. Did I miss something?
