2nd case... Well, even if a server reboot between the polling time, Xymon should notice it. In case of a Linux/Unix server, the uptime, which you can see at the CPU data will change and will show you an alert. So increasing the polling time, is not really necessary, I think.
If you wanna get noticed of the behavior, you might should add an alert, to get an email/SMS, if a machine rebooted.

I monitor our switches, and routers using devmon. You then can get all interesting data via SNMP, which works very well. You then can see traffic, vlan settings, error and much more about your network-hardware. It works like a charm in our Xymon 4.2.3.
