Re: [opennms-devel] Categories and other groupings

Only a user-reflection about categories and groups ;)

we using OpenNMS in very complex networks as isp. If you have a network with
many changes and many ip-subnets, then it is a good way to put functions to
categories, instead of XML-files with IP-based rules.
In that case maintaining is not very easy. One device must be in more than 3 or
4 groups.

I think you can use categories at the moment in two ways.

First grouping your devices for stuff like:
  - surveillance
  - dashboard
  - First-Page on WEBUI
  - SLA-calculations, reporting
  - All other grouping-stuff like geographic, topology, organisation

Second grouping for NMS-functionalities like:
  - notification
  - data-collections (different timeresolutions 60 sec., 300 sec etc.)
  - thresholding
  - polling
    - Default-Polling-Packages
    - Deviceclass-specific Polling-Packages
    - SLA-Polling-Packages
    - ?? and why not capabilityscans, but this is a another question ;)

A possible way i think, is to "tag" your categories to show some other persons,
which category is used for which function (?? meta-categories ;)??). I don't
know if that is the best-practice, but if you have more than one OpenNMS
administrators it can work.

I think to work with categories with NMS-functionalities you have a good control
about OpenNMS. The possibilities with IP-rulebased configurations are in some
cases too inflexible.

Thanks for reading and open for any comments
