Unfortunately, no. Not yet.
We've been kinda lazy implementing this as most devices still support v2c at the very least.
I'd be interested in knowing if you have a device that is SNMP v3 only and what it was.

Typically "the industry" is very slow to adopt new standards, especially when it adds additional complexity like SNMP v3 does. I'm glad to see a device that does support it and uses it. Maybe this will give us the kick we need to get SNMP v3 support in NetMRG ;-)

Hello.

I realised that I wanted to use netmrg with snmpv3 and ksm, well, said and done. Here is how I accomplished it

stracing the gatherer it proved that libsnmp tries to read conf files when loaded, simply create a (in my case) /var/netmrg/.snmp/NetMRG.conf containing something similar to

[snmp]
defSecurityModel ksm
defSecurityName my-netmrg-user
defSecurityLevel authPriv

and remove the comments around snmpv3 in devices.php. works like a charm.

You probably need a slightly different config file if you want to use usm, I have only tried this with ksm. This also implies running the gatherer in a wrapper script getting krb tokens for it.
