I'm experimenting with Zenoss using the 2.1.92 stack installer, and I've
run into a couple of issues with the device modeling:
The first problem is that some of the routers I'd like to monitor have
full BGP routing tables. Adding these devices to Zenoss results in the
creation of a network object for every route in the table (~250,000). I
don't need a network object for every route in existence, and having
that many networks show up in Zenoss makes browsing by network impractical.
The second problem is that some of my other routers have hundreds of
interfaces that I don't need to monitor because they're PPP links that
are expected to go up and down regularly. I can disable the monitoring
using zendmd (script below in case anybody came across this post looking
for that information), but I would prefer to keep those interfaces from
being added to the system.
Is there a way to hook into the modeling process and suppress the
addition of routes and interfaces? If not, then which file(s) would I
want to start in if I wanted to look into adding this as a feature?
Thanks,
