-x : Do not ignore hosts/services with notifications disabled
-z : Do not ignore hosts/services in scheduled downtime
-s : Ignore services in a soft alert state
-h : Show this help text
-d : Enable debug mode. Can help track down script errors.
-L : Give Livestatus API (eg: localhost:6557)
-S : Give location of status.log/dat file (default /u02/nagios/log/status.log)
-O : Give location of objects.cache file (Nagios 3.x) (default /u02/nagios/log/objects.cache)

Script syntax:
Script must resolve to a single value, else it is an error.
Script can contain functions, hosts, services, and literals.
You must quote spaces, or escape with a backstroke.

Literals are of the form:
     status:text
for status of OK,WARN,CRIT,UNKNOWN

Hosts are of the form:
     /hostname
where hostname can be a regexp preceeded by a % or a hostgroup preceded by a :

Services are of the form:
     /hostname/servicedesc
where either or both of hostname and servicedesc can be regexps preceeded by %
You can also specify the host as a hostgroup preceded by a :.
If a service is specified using hostgroup and/or regexp, then only matching
services are implied.  This may mean no matching services at all!  An error
is only given if a non-existant explicit hostname/servicename is given.

Functions are of the form:
     @functionname ( argumentlist )
where argumentlist is a list made up of one or more literals, hosts, services,
or functions.  The functionname can be any of:
  @max : Take the maximum value of the statuses in the list
  @min : Take the minimum value of the statuses in the list
  @cluster : OK if all are OK, critical if all are critical, else warning
  @avg : Mean average status, rounded to nearest
  @median : Median status
  @map : Change text to the text of item with the same status as the first
          item in the list.  Status is the status of the first item.  Use this
          to rewrite the text after calculations.
  @threshold : First item is  dummy threshold definition item.  Add the   
          statuses of all other items and compare to warn/crit thresholds in  
          dummy item.  First item should be of form 0:minc/minw/maxw/maxc and 
          status will go critical if total <minc or >maxc.
  @mapstatus : Take the first item.  If the status matches that of any of 
          the following items, change the status to the second part of the    
          matching item

Example scripts:
 @map ( @max ( @cluster( /%webserver ) @cluster( /%dbserver ) /router ) "OK:All fine" "WARN:Performance degraded" "CRIT:Service unavailable" )
 @mapstatus ( @max( /:hg/DNS ) CRITICAL:WARNING UNKNOWN:WARNING )

The first will go critical if either the router, all of the dbserver* hosts, or all of the webserver* hosts, are critical.  The default status description
is replaced with one of the three given.

The second will check the status of the DNS service on all members of the 
hg hostgroup.  It will take the worst status and map critical and unknown
to warning; therefore it will show warning unless all services are OK.

NOTE: If your regexp contains a space, this wil not work.  Replace spaces
with a '.'.  All scripts are tokenised on whitespace, so spaces around the
brackets are required.  Quotes are not understood.
