Tracking web server latency. Ideas?

We've got series of mirrored web servers. I've been asked to come up with a way (either to build or to buy) to track the latency of each of the IP addresses on each web server.

The preferable solution would be one that can download a page and click a link, timing the whole process.

For the sake of argument, let's assume that I'm a complete idiot about this stuff and need a lot of help figuring this out.

Download Ping Plotter...type in the IP address of the certain server, and it gives you a detailed explanation of where the latency comes from.
 
Can be done with a third party tool such as ~ Mercury LoadRunner, Compuware's QALoad, or Rational's Performance Tester.

If your web applications are .NET, you can utilize what Microsoft has provided such as Microsoft Application Center Test (ACT); which is included with Enterprise editions of Visual Studio .NET, or the Microsoft Web Application Stress tool.

this is good if you're testing network latency, if you think one server's web server is the problem ping plotter won't necessarily find it. Also not so useful if testing on a LAN.

this might help with some timings of web page times with firefox:

don't forget to purge caches between loads. You should be able to test a specific server by using it's IP manually.

You don't specify what platform you are using (and from how you phrased your question I guess you are looking for something web based and that might be hard to find).

What I use is Matt Kimball's Traceroute aka MTR which you should be able to find on the WWW in a complied version for just about any platform.

Not being a Unix (of any flavour) or Windows user that's the closest I can get you to anything I know is useful.

A quick Google for something free turns up Axence NetTools 2.1 at http://www.ezgoal.com/channels/internet/score.asp?f=381176

This sounds pretty powerful.

Bonne chance as they say in my country.

Ah! Light dawneth.

Not places I would voluntarily tread. What you might try are some of the Microsoft newsgroups on Usenet. If you are not currently using/connected to a newsserver, try searching via Google Groups Usenet. It's where I would start (if I really had to).

"Bonne chance", as we say en Canada.
