I regularly set the polling cycle to 1m for all network tests and, as long
as your box can handle it, would usually recommend the same.

You should probably set [xymonnetagain] to something lower, like ~15s.

One trick: modify ext/xymonnet-again.sh to read/append a static file as
well as tmp/frequenttests.* , and then keep a list of super-important
hosts in there. This way you can have your, eg, dns servers checked at
~10/15s and everything else checked in the normal period.
