There are many IT monitoring platforms that should be able to do this. Probably the most popular and robust is Nagios, which can be set up to monitor services as well as network hardware.

Though to prevent this sort of thing from happening in the future, you should use a bytecode caching PHP accelerator that's set to use different disk caches for different vhosts (it's possible eAccelerator can be configured to do this, as there seems to be a way to set different configurations for different vhosts), setting storage quotas for each user, and put each vhost in a separate user directory.

Also, eAccelerator doesn't ever clear its disk cache. It's up to you to run a cronjob that clears/refreshes the disk cache every once in a while. It doesn't seem very efficient, but that seems to be how it's designed. There should be other PHP accelerators that can delete old cached versions and only refresh the cache when the modified date has changed for a PHP file.
