If you need to inspect e.g. free space on remote servers it may be more
sensible to use SNMP or some such similar protocol/system that is
designed for exactly this purpose rather than try to hack up a system in
PHP (tho' I do love my hacking!)
Have a look at Nagios. I'd imagine your servers will have some degree of
health monitoring/reporting installed anyway for your own peace of mind,
so it shouldn't be too hard to hook into that system.
