Verify this bug in "libvirt-snmp-0.0.3-5.el7_6.1.x86_64" Version: kernel-3.10.0-957.el7.x86_64 qemu-kvm-rhev-2.12.0-19.el7_6.2.x86_64 libvirt-4.5.0-10.virtcov.el7_6.3.x86_64 libvirt-snmp-0.0.3-5.el7_6.1.x86_64 Configuration: 1. Install libvirt-snmp, libvirt-snmp-debuginfo, net-snmp net-snmp-libs, net-snmp-utils components 2. Modify "/etc/snmp/snmpd.conf" as following: # cat /etc/snmp/snmpd.conf rwcommunity public master agentx trapcommunity public trap2sink localhost 3. Modify "/etc/snmp/snmptrapd.conf" as following: # cat /etc/snmp/snmptrapd.conf authCommunity log,execute,net public logOption f /var/log/snmptraps.log 4. Modify "/etc/sysconfig/snmptrapd" as following: # cat /etc/sysconfig/snmptrapd OPTIONS="-m ALL -p /var/run/snmptrapd.pid" 5. Restart related service # systemctl restart snmpd # systemctl restart snmptrapd # systemctl restart libvirtd Steps: 1. Run libvirt snmp agent daemon through the following cmd on "Terminal 1" # LIBVIRT_DEFAULT_URI="qemu:///system" libvirtMib_subagent -f -L -D ALL 2. Open ths third terminal to check the log on "Terminal 2" # tail -f /var/log/messages | grep --line-buffered "localhost [UDP: [127.0.0.1]" 3.
