I tried setting up my env based off of documentation I pieced together from:

• README.md
• https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-python-middleware.html
• https://docs.aws.amazon.com/xray-sdk-for-python/latest/reference/frameworks.html#django

settings.py

XRAY_RECORDER = {
    'AUTO_INSTRUMENT': True,  # If turned on built-in database queries and template rendering will be recorded as subsegments
    'AWS_XRAY_CONTEXT_MISSING': 'LOG_ERROR',
    'AWS_XRAY_TRACING_NAME': 'Site',
    'DYNAMIC_NAMING': '*.local.site.net', # defines a pattern that host names should match
}

I added the MIDDLEWARE and the INSTALLED_APP.

Prior to this error I was getting something similar to #4

aws_xray_sdk.core.exceptions.exceptions.SegmentNotFoundException: cannot find the current segment/subsegment, please make sure you have a segment open

I had to set the AWS_XRAY_CONTEXT_MISSING setting to LOG_ERROR to avoid it and then got this error. Any help is appreciated.

Hi, I was unable to reproduce the issue you reported. What is the X-Ray SDK version you are using? Do you mind sharing your settings.py file with parts that has X-Ray related configs? Do you use python manage.py runserver to start your application or some other commands?

Are you using pre-1.10 style middeware config? https://github.com/django/django/blob/stable/1.11.x/django/core/handlers/base.py#L55 The error you are seeing comes from loading key MIDDLEWARE_CLASSES from settings file.

The X-Ray SDK currently only supports 1.10 style middleware with key MIDDLEWARE as you can see on the README.

[michaelhelmick]

Ah, I am. Thank you. Ill reopen if that doesn’t work!

Feel free to open new issues with any additional problem you hit. Thanks.

Changing to MIDDLEWARE got rid of the error in this issue but is throwing an issue similar to #4 still.

Based on this line of your stack trace

File "/Users/mikehelmick/.virtualenvs/test-xray/lib/python2.7/site-packages/django/db/backends/mysql/base.py", line 386, in mysql_version
    cursor.execute('SELECT VERSION()')

I believe https://docs.aws.amazon.com/xray-sdk-for-python/latest/reference/frameworks.html#django section "Local Development" can answer your question.

4 is about S3 resource level API provided by boto3.

[michaelhelmick]

Ah. I think everything was solved once I actually ran the daemon locally. Prior, no events were sent.

Sounds great. I'm glad everything works out for you. Feel free to provide any general feedback at our forum: https://forums.aws.amazon.com/forum.jspa?forumID=241&start=0 or open new issues for Python SDK specifically.

I've implemented what has been discussed on this thread. Now getting this error when i runserver

TypeError: object() takes no parameters

[michaelhelmick]

Chances are one of your other Middlware has t been updated using the Django compat middleware. I can post a code example of how to fix it manually in a couple hours when I’m home. I suggest trying to upgrade any third party libraries that implement middleware first though. Easiest way is probably commenting out all third party middleware and enabling one by one and find the culprit

Apparently one of my middleware libraries was not up to date. runserver is ok now. However, i'm getting

SegmentNameMissingException.

my xray configuration is

XRAY_RECORDER = { 'AUTO_INSTRUMENT': True, 'AWS_XRAY_CONTEXT_MISSING': 'LOG_ERROR', 'AWS_XRAY_DAEMON_ADDRESS': '127.0.0.1:2000', 'AWS_XRAY_TRACING_NAME': 'example config', 'DYNAMIC_NAMING': '*.example.com', 'PLUGINS': ('ElasticBeanstalkPlugin', 'EC2Plugin', 'ECSPlugin'), 'SAMPLING': False, }

Any help on this would be appreciated. Thanks

[patrickohemeng]

I set the AWS_XRAY_TRACING_NAME as an environmental variable and everything works now.
