Hi Ben,
You can suppress route table scanning by setting zProperty
"zCollectorIgnorePlugins" to "RouteMap". You can add this property to
all routers at once, or just a single router by taking advantage of the
Zenoss class hierarchy.

Zenoss uses routes to understand your network topology.

Hello,
I am trialling zenoss via the provided vmware image. I have noticed since
adding about 6 or so devices (cisco routers) the cpu on my server sits
permanenty at 100%.
This server has 2 x 2.4GHz xeons and 1Gb or RAM so should be plenty powerful.
The vm machines runs out of memory with 384Mb so I increased it to be 640Mb.
But this does not change the cpu usage.
It does not seem right given there is only a trickle of snmp traps hitting the
box. Adding the devices caused a lot of traffic as zenoss seems to download the
entire routing table from each router - very bad if has a full bgp table!!! But
this is a few days after adding the new devices now..
Can anyone say if this high cpu usage is exhibited in a proper installation? I
can't possibly scale zenoss to the 500 devices I want to monitor if this is the
case.
cheers,
Ben
