Hosted/NonHosted service monitoring applications

Hey Guys,

I was wondering what other people are using for monitoring the status of services like httpd, mysqld etc on their servers. At work we run a nagios box in-house that montiors everything from httpd to cpu load and hard drive space on our servers but it took me ages to configure and I’m wanting to know of some good solutions for my (freelance) clients as there are only a few and its not worth setting up a nagios box for them alone.

Some quick googling I found some pretty crapy looking services, where’s the nice web 2.0 app’s for monitoring? something with some proper polish :frowning:

Thanks in advanced,
