timing a web response using urllib.urlopen??

[MCollins@seminolecountyfl.gov]

hi all,

python newbie alert! i'm trying to open an array of websites, timing each
site's response time (how may seconds until a response)

if someone could point me in the right direction on accomplishing the
timer part of the this application, i'd appreciate it.

thanks in advance

class timer:
def __init__(self,n ame,level=0,par ms=""):
self.name = name
self.parms = parms
self.starttime = time.time()

def report(self):
elapsed = time.time() - self.starttime
timefile = open("your filename here", 'a')
print >>timefile, "%s\t%f\t%s " % (self.name, \
elapsed, self.parms)
timefile.close( )

timer = new timer("eggs")
# Do something that takes time
timer.report()

name: in my case identified the database query that was executed
repeatedly.
parms: the parameters of a particular execution of the query.

I imported the output in a PostgreSQL database table to query the data.

create table timer(
name varchar,
elapsed float,
parms varchar
);

\copy timer from 'timefile.txt'

select name, count(elapsed), sum(elapsed)
from timer
group by name
order by sum(elapsed) desc;

This requires

import time

of course.
