So your suggestion is to have the -d option set to 60s for a 20s check 
interval?

The documentation page seems to suggest that the -d option should be a
slightly longer than the check interval.

If there's anything in your nagios system which will cause the nagios
daemon to do something other than scheduling checks for a few seconds,
then with a 10s standard interval it wouldn't take much to throw the
plugin off kilter.  I don't know for sure which activities would do
this, but suspect one would be writing to the status.dat file and
another might be processing the command file.  Having said that, with
the check_snmp_int.pl plugin allowing up to 300% of the -d value
before complaining, it should be fairly forgiving.
