NAME
       ttproclist - Process a template with a nodelist

SYNOPSIS
       torrus ttproclist --tmpl=TFILE --out=OFILE --nodes=NFILE	[options...]

DESCRIPTION
       This command takes a Template-Toolkit template and a list of nodes
       (usually	SNMP devices) as input.	The output file	is a result of
       template	substitution, according	to the specified options.  Command-
       line options --tmpl, --out and --nodes are mandatory.

       This utility can	be used	to generate the	discovery instructions XML out
       of a predefined template	and a dynamically generated list of devices.
       Alternatively, it can produce Torrus XML	configuration for a given list
       of objects, etc.

       The following variables are predefined when the template	is processed:

       o   "nodes"

	   Hash	array of nodes.	Hash keys are the node names. Values are
	   symbolic names. If symbolic names are not defined, values are the
	   same	as keys.

       o   "param"

	   Hash	array of command-line parameters given in --param option.

       o   "nodesfile",	"creator"

	   Informative variables. They can be used to produce the creation
	   note	in the resulting files.	"nodesfile" returns the	file name of
	   nodes, and "creator"	returns	a detailed information how the file
	   was generated, with timestamp and command line options.

OPTIONS
       --tmpl=TFILE
	   The file name of the	input template.	Relative names are looked in
	   the current directory and in	/usr/local/etc/torrus/templates. The
	   file	name may also be an absolute path.

       --out=OFILE
	   Output file name. If	no absolute path given,	the file is written in
	   the current directory.

       --nodes=NFILE
	   The name of the nodes list. Nodes should be separated by space or
	   tab character or newline. Additional	information, referred to as
	   symbolic name, can be supplied after	a colon, of the	form
	   NODENAME:SYMBOLICNAME.

       --param=NAME:VALUE,NAME:VALUE...
	   List	of optional parameters that may	be used	in the template.

EXAMPLES
       The following example gerenates "devdiscover" input file	from a
       template.  The template is as follows:

	<?xml version="1.0" encoding="UTF8"?>
	<snmp-discovery>
	>>> usual DDX parameters here, like SNMP community and data-dir
	 <param	name="snmp-community" value="private"/>
	 <param...
	>>> This loop generates	per-host entries
	 [% FOREACH n =	nodes.keys.sort	%]
	 <host>
	   <param name="snmp-host" value="[% n %]"/>
	   <param name="symbolic-name" value="[% nodes.$n %]"/>
	   <param name="output-file" value="nodes/[% n %].xml"/>
	 </host>
	 [% END	%]
	>>> Generate the bundle	file, so that you need only one
	>>> entry in torrus-site-config.pl
	 <param	name="output-bundle" value="[% param.BUNDLE %].xml"/>
	</snmp-discovery>

       The following command would generate MY.ddx from	template file
       MY.ddtmpl as described above. The file MY.nodes is a list of SNMP
       devices,	one per	line. Then "devdiscover" is launched with MY.ddx as
       input. Note also	the short form of the command line wrapper.

	torrus ttproclist --tmpl=MY.ddtmpl \
	  --nodes=MY.nodes \
	  --out=/usr/local/etc/torrus/discovery/MY.ddx \
	  --param=BUNDLE:MYNODES

	torrus dd --in=MY.ddx --verbose

       In addition, you	may put	some common parameters in Template BLOCK
       statement in a separate file, and INCLUDE it in your templates. See the
       Template-Toolkit	documentation for more detail.
