Nair,
As all good consultants would say, "It depends."
There is a small network load for every test so setting shorter intervals
increases the load. If you double the number of tests in an hour, you
double the load.  So if you have a large number of tests on a large number
of machines, doubling the frequency of the tests is probably a bad idea.
What value do you think would accrue from increasing the frequency of
tests?
In my network, Nagios is set to start sending email notifications if the
failure condition persists more than 3 test periods, i.e., the remote disk
root partition is unreachable for longer than 30 minutes.  This particular
test fails on my ftp server during large file transfers, with the message,
plug-in timed out.  This has not turned out to be an actual problem, but is
an artifact of flooding the network with file-transfer traffic.  In this
case it is more sensible to let the file transfers go through than to know
to an utmost certainty that the drive is not too full.

YMMV

Wolf
