Net Observer lets you observe outgoing Net::HTTP requests that your Ruby application makes. This can be useful when it fails at the remote end and you want to report the exact request that caused the problem.
Create a NetObserver::Logger instance to log the requests and
reponse. Use the NetObserver::Base class to observe the requests in
another way.
This:
require "net_observer"
require "logger"
log = Logger.new(STDOUT)
net_logger = NetObserver::Logger.new log
Net::HTTP.get URI.parse("http://google.com/search?q=wikipedia")
produces:
I, [2010-12-14T12:42:50.570907 #23968] INFO -- : get request for url http://google.com:80/search?q=wikipedia with method: GET with body
