I have installed nagios plugins and I don't understand, why check_snmp is not working properly. for example, I use "-r" option (as describe in docs) port Fa0/14 on switch is UP inframonitor:/usr/local/icinga/libexec # /usr/local/icinga/libexec/check_snmp -H 192.168.111.60 -C xxxxx -o ifOperStatus.10014 -r 1 -m RFC1213-MIB SNMP OK - 1 | RFC1213-MIB::ifOperStatus.10014=1 port Fa0/10 on switch is DOWN inframonitor:/usr/local/icinga/libexec # /usr/local/icinga/libexec/check_snmp -H 192.168.111.60 -C xxxxx -o ifOperStatus.10010 -r 1 -m RFC1213-MIB SNMP OK - 2 | RFC1213-MIB::ifOperStatus.10010=2 Port fa0/10 is DOWN, but plugin returns the status OK(!). It is wrong. Can you help me to solve this problem? inframonitor:/usr/local/icinga/libexec # rpm -qa | grep net-snmp net-snmp-utils-5.4.2.1-9 net-snmp-5.4.2.1-8.2.1 net-snmp-libs-5.4.2.1-9 net-snmp-mibs-5.4.2.1-9 nagios-plugins-1.4.15 </blockquote></div>
