Strange CPU usage on a CISCO Router.
I poll just 1 time a minute to recive just one MIB value (CPUbusy)
to check the CPU usage of the router.
Nearly periodically every half houre the CPU usage go up to 70%.
Once or twice a day the CPU usage go up to 99% - 100% for 1 houre.
in this time, the router shows me 85% of CPU usage go to IP SNMP Process.
Its a CISCO 2500 with IOS 11.3
Is it possible that NetView with one Request a minute is resonsible
for this??? I cant belive. But ther is no other machine using
SNMP to acces the router. And the SNMP process thakes 85% of CPU.
I check the interfaces for SNMP trafic. It is close to zero.
