+1 for Nagios. And you can use just about any old server/workstation you have sitting around for linux, you could even use a virtual server for it if you needed to.
We use Nagios for monitoring our internal network, numerous web-sites, vpn tunnels and a bunch of servers at our colo facility. We actually run 2 instances of Nagios, one internal and one at the colo, they provide checks for each other, and a couple of ways of reporting it via Nagios web-site and emails. We use our internal linux box to run a variety of things including Nagios, LDAP, SyslogNG, Cacti and even an ET game server during lunch time ;) You would still have a separate web-site for each clients location with Nagios, however, you can centralize the email notifications. Nagios can monitor probably everything that you could think of that you would want to monitor. On a side note, Nagios actually stands for Notices All Glitches In Our Systems.
