Yes snmp request can kill the control plane of EXs. For example 
Observium was killing my ex4550 (causing ldp sessions to drop and so 
on). I still consider that completely ridiculous...

With correct snmp filter the situation is less worse, but I still have 
to patch the Observium poller to let some breathes to my ex(s).
OK the Observium poller is quite aggressive (or stupid depend of the 
point of view :).

I've made some ugly scripts in python to check via ssh the output of 
"show virtual-chassis".

Check-mk is great, but do lot of snmpwalk to check network devices. (If 
I had time I will take a look to patch and make it use an interfaces cache)
