You could also do ssh or even telnet, if you have them enabled.
You did not ask, but a comment on uptime. You can use it to detect router
bounces, detecting rogue reloads or perhaps system crashes. I have it to go to
critical whenever the uptime is below X minutes, and email out. Network tests
such as ping, snmp or ssh availability might miss a quick box's trip down, but
uptime will always catch a reload.
