On the system everything works. But after the update to the newest kernel with all secure relevant patches the system is working fine, but Nagios don’t get speed or traffic information from the network card ‘eth0’. Why?
I installed all patches on 2012.02.11 on this VM. Since this update i checked for new updates, but for i haven’t a solution.
I test it last Friday again to update a second test VM. After the update i got the same error on this vm.
I tested a other Plugin to check the traffic with same result. I can’t get the information about traffic and speed from network over snmp.
