Did you ever want to write sophisticated Nagios/Naemon config files using the power of template toolkit? Basically this is a config preprocesseor.
The input folder(s) should contain some templates and a source of hosts and contacts. Then all will be put together into a clean and maintainable nagios configuration.
The input folder looks like a nagios config folder but you are allowed to use Template Toolkit Syntax.
For example:
input/ |-- cgi.cfg |-- conf.d | |-- apps # will be processed for every host | | `-- apache.cfg # will be processed for every host with app tag apache | |-- contacts # will be processed for every contact | |-- contacts.cfg | `-- hosts | |-- linux # every host of type linux | | |-- centos.cfg # every host of type linux with tag centos | | `-- debian | | |-- squeeze.cfg # every host of type linux with tags debian and squeeze | | `-- wheezy.cfg | `-- switch.cfg |-- nagios.cfg |-- resource.cfg |-- static # static files will just be copied into destination folder | `-- conf.d | |-- commands.cfg | `-- timeperiods.cfg |-- hooks # pre/post hooks `-- post_process* # scripts will be run after processing is finished
All files are nagios configuration files, but you may use template toolkit syntax to add some magic to those files. Any folder below conf.d except 'apps', 'contacts' and 'hosts' will be processed only once. The 'apps' and 'hosts' folder will be processed for every host, the 'contact' folder for every contact.
then run the montt processor:
%> ./montt input/ output/
The processor won’t overwrite existing files, so export the new config into a new empty folder and move files afterwards. You can automate this step with hooks.
Hooks are scripts which are run at certain points of the export procedure. Hooks have to be executable and have to be placed in a hook folder below the input directory.
All hooks will be run with a comma seperated list of input folders as argument.
ex.:
inputfolder1/hooks/pre inputfolder1,inputfolder2
