Python - URL Timer - Web Monitor Utility

In a previous post, I showed how to insert timers between steps in an http request to do some basic profiling. Peter Bengtsson contacted me with some enhancements to the original code. I took his enhancements and added some more of my own to create a neat little web monitoring utility.

It uses Python's httplib to send a GET requests at regular intervals to a URL and adds some timing instrumentation between each step of the request/response. Results are printed to the console.

get it here:
http://code.google.com/p/corey-projects/source/browse/trunk/python2/url_timer.py

to use, give it a site and interval:

> python url_timer.py www.goldb.org 5

... or an https/ssl url and an interval:

> python url_timer.py https://ssl.sonic.net/ 5

sample output:

>python url_timer.py www.goldb.org 5
request sent         response received    content transferred  size
