Cannot use snmp_check with snmp v3

[pablo muñoz]

Hello.

He is sure that the keys are well?

try to translate the MIB DISMAN-EVENT-MIB :: sysUpTimeInstance

For example:

/usr/lib64/nagios/plugins/check_snmp -H 192.168.254.2 -o .1.3.6.1.2.1.1.3.0 -P
3 -L authPriv -a MD5 -x DES -X v3p4ssword#2 -U snmpv3user  -A v3p4ssword#1



Atte.
