COMBO.CFG(5)		       File Formats Manual		    COMBO.CFG(5)

NAME
     combo.cfg - Configuration of combostatus tool

SYNOPSIS
     $XYMONHOME/etc/combo.cfg

DESCRIPTION
     combostatus(1)  uses  it's own configuration file, $XYMONHOME/etc/combo.cfg
     Each line in this file defines a combined test.

FILE FORMAT
     Each line of the file defines a new combined test. Blank  lines  and  lines
     starting with a hash mark (#) are treated as comments and ignored.

     The  configuration  file  uses the hostnames and testnames that are already
     used in your Xymon hosts.cfg file. These are  then  combined  using  normal
     logical operators - "||" for "or", "&&" for "and" etc.

     A	simple	test - e.g. "Web1.http" - results in the value "1" if the "http"
     test for server "Web1" is green, yellow or clear. It yields the  value  "0"
     if it is red, purple or blue.

     Apart  from  the logical operations, you can also do integer arithmetic and
     comparisons. E.g. the following is valid:

     WebCluster.http = (Web1.http + Web2.http + Web3.http) >= 2

     This test is green if two or more of the http tests for Web1, Web2 and Web3
     are green.

     The full range of operators are:

	     +	    Add
	     -	    Subtract
	     *	    Multiply
	     /	    Divide
	     %	    Modulo
	     |	    Bit-wise "or"
	     &	    Bit-wise "and"
	     ||     Logical "or"
	     &&     Logical "and"
	     >	    Greater than
	     <	    Less than
	     >=     Greater than or equal
	     <=     Less than or equal
	     ==     Equal

     There is currently no support for a "not" operator. If you need it, use the
     transcription "(host.test == 0)" instead of "!host.test".

     NB: All operators have EQUAL PRECEDENCE. If you need something evaluated in
     a specific order, use parentheses to group the expressions together.

     If the expression comes out as "0", the combined test goes red. If it comes
     out as non-zero, the combined test is green.

     Note: If the expression involves hostnames with a character that is also an
     operator - e.g. if you have a host "t1-router-newyork.foo.com" with a  dash
     in  the hostname - then the operator-character must be escaped with a back-
     slash '\' in the expression, or it will  be  interpreted  as  an  operator.
     E.g. like this:

      nyc.conn = (t1\-router\-nyc.conn || backup\-router\-nyc.conn)

EXAMPLE
     WebCluster.http = (Web1.http || Web2.http)
     AppSrvCluster.procs  =  (AppSrv1.conn && AppSrv1.procs) || (AppSrv2.conn &&
     AppSrv2.procs)
     Customer.cluster = WebCluster.http && AppSrvCluster.procs

     The first line defines a new  test,  with	hostname  "WebCluster"	and  the
     columnname  "http".  It will be green if the http test on either the "Web1"
     or the "Web2" server is green.

     The second line defines a "procs" test for the "AppSrvCluster" host.   Each
     of  the  AppSrv1  and  AppSrv2 hosts is checked for "conn" (ping) and their
     "procs" test. On each host, both of these must be green, but  the	combined
     test is green if that condition is fulfilled on just one of the hosts.

     The  third line uses the two first tests to build a "double combined" test,
     defining a test that shows the overall health of the system.
