/**
 * Does the actual work of checking something.
 *
 * @param string $id
 *   Optional, an identifier which is the 2nd argument passed via the URL.
 *   this is useful when you just want nagios to check a single function.
 *   example: http://mysite.com/nagios/mymodule/myId.
 *
 *   "myId" would be send to mymodule_nagios.
 *
 *   http://mysite.com/nagios/mymodule would not send any id, but would not
 *   run hook_nagios for any other modules.
 *
 * @return array
 * The data returned is an associative array as follows:
 *
 *   array(
 *     'key'  => 'IDENTIFIER',
 *     'data' => array(
 *       'status' => STATUS_CODE,
 *       'type    => 'state', // Can be a 'state' for OK, Warning, Critical, Unknown) or can be 'perf', which does
 *                            // Cause an alert, but can be processed later by custom programs
 *       'text'   => 'Text description for the problem',
 *     ),
 *   );
 *
 * STATUS_CODE must be one of the following, defined in nagios.module:
 *
 *   NAGIOS_STATUS_OK
 *   NAGIOS_STATUS_UNKNOWN
 *   NAGIOS_STATUS_WARNING
 *   NAGIOS_STATUS_CRITICAL
 *
 * Here is an example:
