我想boto3使用 X-Ray 开发工具包跟踪对 Python AWS 开发工具包 ( ) 的调用。根据X-Ray 文档，我必须修补boto3. 然后 X-Ray 将自动创建子段，因此我只需将 AWS 开发工具包调用包围在一个段内。这是我的代码：

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")

首先我启动 X-Ray 守护程序，然后运行脚本。但是，守护程序返回以下错误：

2018-07-27T15:33:01+08:00 [Info] Successfully sent batch of 1 segments (0.146 seconds)

此外，当我在 AWS 控制台上查看 X-Ray 时，服务图和跟踪上都没有出现任何内容。

在网上搜索，我找不到此错误的任何实例。我错过了什么？

I asked on the AWS forums and got an answer.

If an argument is passed to xray_recorder.end_segment(), it is automatically parsed as epoch in seconds. It can be left blank.
