       ttproclist - Process a template with a nodelist


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


       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:

       ·   "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.

       ·   "param"

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

       ·   "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.


           The file name of the input template. Relative names are looked in
           the current directory and in /etc/torrus/templates. The file name
           may also be an absolute path.

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

           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

           List of optional parameters that may be used in the template.


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

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

       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 \

        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.
