Re: [opennms-capsd] information regarding capsd

[Shane O'D. <sh...@op...>]

For a good place to start, the following might help.  This comes from
Sowmya, who knows everything there is to know about capsd.  Treat this as
the ultimate high-level overview and a precursor to the white paper.

Feel free to post any questions back to this list.  Here's Sowmya's notes:

In terms of code/data  to have capsd discover new services, the places to
look at would be:

 - CapsdPluginConf.xml
This has plugins to be used for each service - i.e the class to use to poll
for that service

 - CapsdPluginLoader.java
This loads the plugins from the 'CapsdPluginConf.xml' and adds services from
here into the DB (if not already in the DB)

 - CapsReader.java
Uses the plugins defined in the CapsdPluginConf to poll

 - org/opennms/bb/dp/capsd/plugin/*
In order for the CapsReader to be able to use the plugin, it needs to
implement the 'CapsdPlugin' interface in this directory as all plugins in
this directory do

Note that this list does not include scheduler related changes.
