Different check_http?

[Richard Luys-Nagios User]

Yolanda,

With the plugin package came (if I'm not mistaken) a small binary called  
'negate'. This should be in your plugin directory. With this you can  
negate the returncodes of your plugins; ie: Error becomes Ok, and vice  
versa. See the help output of negate below:

negate (nagios-plugins 1.3.1) 1.5.2.2
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:
   -t, --timeout=INTEGER
     Terminate test if timeout limit is exceeded (default: 9)
      [keep this less than the plugin timeout to retain CRITICAL status]

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.

Send email to nagios-users at lists.sourceforge.net if you have questions
regarding use of this software. To submit patches or suggest improvements,
send email to nagiosplug-devel at lists.sourceforge.net
