You might check out "negate" which I believe is part of the standard
plugin distro:
negate (nagios-plugins 1.4.0alpha1) 1.13
The nagios plugins come with ABSOLUTELY NO WARRANTY. You may
redistribute
copies of the plugins under the terms of the GNU General Public License.

Negates the status of a plugin (returns OK for CRITICAL, and
vice-versa).
Usage: negate [-t timeout] <definition of wrapped plugin>
negate (-h | --help) for detailed help
negate (-V | --version) for version information
Options:
-h, --help
Print detailed help screen
-V, --version
Print version information
-t, --timeout=INTEGER
Seconds before connection times out (default: 9)
[keep timeout than the plugin timeout to retain CRITICAL status]
negate "/usr/local/nagios/libexec/check_ping -H host"
Run check_ping and invert result. Must use full path to plugin
negate "/usr/local/nagios/libexec/check_procs -a 'vi negate.c'"
Use single quotes if you need to retain spaces
This plugin is a wrapper to take the output of another plugin and invert
it.
If the wrapped plugin returns STATE_OK, the wrapper will return
STATE_CRITICAL.
If the wrapped plugin returns STATE_CRITICAL, the wrapper will return
STATE_OK.
Otherwise, the output state of the wrapped plugin is unchanged.
