If I run snmpwalk on the same machine of zabbix server I can collect data with SNMPv3
snmpwalk -v3 -u Usnmp -l AuthNoPriv -a MD5 -A 'AuthPass' 10.x.x.x .1.3.6.1.2.1.1.3.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (61650508) 7 days, 3:15:05.08
But in Zabbix Server I can't.
Zabbix do not give me data, queue always empty for SNMPv3 agent, error message in front end no even error message in the log.
My zabbix config:
Type: SNMPv3 agent
Key: SysUptime
Host interface: 10.x.x.x:161
SNMP OID: .1.3.6.1.2.1.1.3.0
Security name: {$SNMP_SECNAME}
Security level: authNoPriv
Authentication protocol: MD5
Authentication passphrase: {$SNMP_AUTH}
