Website performance monitoring tools

Question

I have websites that we are performance tuning and wanted to know if anyone has a good tool for monitoring secure web sites? What I am looking for is a tool that can log on to a web site and test a few links and the performance. At least one of the links will access another web-based product using single sign on. I would set it up to check the site every 5 to 15 minutes, record how long each page takes to render in the browser, and send an alert if anything goes wrong. Have you used anything like that that worked well (or very poorly)?

Answer 1

You should have a look at this link (from today):

"How do you test the performance of a website?"

Answer 2

IBM make a product called IBM Tivoli Composite Application Manager for Response Time which does exactly what you want.

It's pretty good but not cheap.

Disclosure: I work for Orb Data, an IBM Business Partner that both sells and provides consultancy for this and other IBM Tivoli products.

Edit: I think the other post was about a development tool - this is more for monitoring production systems which I think is what the poster wants.

Answer 3

I like Alertfox.com

It has by far the best web transaction performance monitoring of all the 15+ services I tested. They also have decent free plans, if money is an issue.
