I have an RHEV 6 hypervisor...

Below is my snmpd.conf file SNMP v3 file

master agentx

I m able to do snmpwalk locally..
snmpwalk -v 3 -u root -l auth -a SHA -A Password0 -x AES -X sharedkey001 172.19.3.168

We need RHEV to send traps to NMS server whenever there is power supply failure....

how to find oid for power supply in RHEV and how to send snmptrap for V3

As you've been asked before, please put your code into CODE tags. And your question makes very little sense.

You say that you've already installed and configured SNMP, and an successfully do an snmpwalk....then say that you need to configure it to send traps (you already have). Then mention a power-supply OID, but don't bother telling us what kind of hardware you're using (which is obviously enough where you would GET any OID's...from that manufacturer).

Check with whoever made your hardware for whatever SNMP resources they may have. And, as you've been told before...contact Red Hat support for help, since you're using RHEL, and should be PAYING FOR IT

Red Hat updated to use trapsess to send snmp v3 traps.. But trapsess command does not exists in my RHEV.... Post installation of RHEV, I had just enabled snmp.... I have the below packages installed, in internet they say 'trapsess' is automatically available if the net-snmp package is installed, but its not there in RHEV.... To cross check installed snmp packages in RHEL, even in RHEL servers there is no trapsess command...


net-snmp-5.5-44.el6_4.4.x86_64
net-snmp-libs-5.5-44.el6_4.4.x86_64
net-snmp-utils-5.5-44.el6_4.4.x86_64


Requirement is: RHEV should send snmp v3 traps to OpenNMS...... Right now, it sending traps but I receive it as V2 in NMS....

Ok, then your 'requirement' should also include: CONTACTING RED HAT SUPPORT. AGAIN, you need to be PAYING for RHEL/RHEV. Neither are free products, and chances are you don't have that package/program because you're not paying for it, so it didn't get installed from the online repositories. There are several bugfixes mentioned in the Red Hat custom portal, as the pertain to SNMP and trapsess.

And if you read the SNMP documentation from Red Hat, you'd also see you're missing the trapsess engine option in the SNMP configuration.
