Here’s what I currently use to determine how long it takes to generate a page in PHP. Its only 8 lines of code.

I found a useful script in PHP that can be used for checking uptime of a server. It can be useful for checking when the servers have a such a significant load that pages can’t be displayed. The benefit or running it locally is that I can configure the script to perform failover functionality if necessary. Online uptime services are good too, but most of them aren’t free. Maybe I should force the server to show a failwhale when the site gets too busy… j/k

Here’s the link to the script.
