BENCHMARKABLE by Aman King

bitbucket.org/amanking/benchmarkable/

A module that allows a class to mention which instance methods to benchmark, and then allows retrieving the benchmark report in csv format from the class's instances. The csv includes the method invocation timestamp, some context description (if provided), the method name along with arguments passed for the invocation, and the number of seconds the method took to execute.

Eg: class Gateway

# ...
def make_request(url)
  url = URI.parse(url)
  Net::HTTP.start(url.host, url.port) {|http|
    http.get('/index.html')
  }
rescue => error
  puts "Unexpected error: #{error.message}"
end
# ...

include Benchmarkable
benchmark :make_request

end

gateway = Gateway.new gateway.make_request('www.google.com/') gateway.make_request('www.yahoo.com/') gateway.make_request('www.wikyblog.com/AmanKing/') File.open('./gateway_performance_report.csv', 'a+') do |file|

file.puts gateway.benchmark_report.to_csv(:starting_context => 'gateway')

end

Output (in gateway_performance_report.csv): “2009-09-10T20:13:59+05:30”,“gateway”,“make_request www.google.com/”,“0.306514978408813” “2009-09-10T20:13:59+05:30”,“gateway”,“make_request www.yahoo.com/”,“1.08063411712646” “2009-09-10T20:14:00+05:30”,“gateway”,“make_request www.wikyblog.com/AmanKing/”,“2.1521680355072
