Re: [squid-users] Proxy performance monitoring
not necessarily a test lab setup, but something that sits on a client machine, pulls down some static content, at regular intervals and then report on the performance. what I am trying to do is simulate the client experience so to speak. cheers Ivan On Sun, May 2, 2010 at 12:52 PM, Amos Jeffries wrote: > Ivan . wrote: >> >> thanks >> >> What am I looking for is something more along these lines. >> >> >> http://www.webperformanceinc.com/library/files/proxy_server_performance.pdf >> >> >> cheers >> Ivan > > Oh. > > That paper describes requirements for a lab test.

That paper describes requirements for a lab test. The good test software; polygraph etc, have not changed AFAIK so go with those mentioned if you want to. What your initial email seemed to describe was for monitoring live production installation performance. Be aware these are very different. Throwing lab data at a production server to a real remote web service is a very quick way to get yourself a huge bandwidth bill and annoyed phone calls.

[squid-users] Proxy performance monitoring
Hi I recently implemented a new proxy system. I am looking at doing is setting a periodical test that goes out to the Internet, pull some content down and record the relevant metrics. PC>Proxy--->FW-->Internet>Site-with-content Some sort of scheduled process on a PC, that pulls down some static content from the same website, which is repeatable. The application would then record metrics such as speed, time taken to download the static content and log that. I have been digging on this site http://www.opensourcetesting.org/performance.php looking at tools that are available, but I would appreciate any info if anyone has down something similar. Thanks Ivan
