:mod:`github2` uses :mod:`logging` to report warnings, errors and debug messages to the library's user. The Python documentation includes thorough documentation for the :mod:`logging` module, and a wonderful tutorial.

With the DEBUG logging level enabled a message will be produced every time an API request is made.

>>> github = Github()
>>> user = github.users.show("JNRowe")
URL:[https://github.com/api/v2/json/user/show/JNRowe]
POST_DATA:None
RESPONSE_TEXT: [{"user":{"gravatar_id":"e40de1eb6e8a74cb96b3f07f3994f155","company":null,"name":"James Rowe","created_at":"2009/03/08 14:53:38 -0700","location":"Cambridge, UK","public_repo_count":41,"public_gist_count":64,"blog":"http://jnrowe.github.com/","following_count":5,"id":61381,"type":"User","permission":null,"followers_count":6,"login":"JNRowe","email":"jnrowe@gmail.com"}}]
>>> user.gravatar_id
u'e40de1eb6e8a74cb96b3f07f3994f155'

In the message you can see the URL that was accessed, here https://github.com/api/v2/json/user/show/JNRowe. You'll also see any HTTP post method data that was sent, in this case there was none. And the full response from GitHub, here the user data of JNRowe.

If rate limiting is enabled, with the requests_per_second when creating a :class:`~github2.client.Github` object, then you'll see a WARNING level message when a request has been delayed.

>>> github = Github(requests_per_second=0.2, debug=True)
>>> user = github.users.show("JNRowe")
>>> user = github.users.show("JNRowe")
delaying API call 4.99773

Here we have defined a rate limit of one call every five seconds, and doing so has imposed an almost 5 second delay before completing the second request.
