snmp v3 on check_nwc_health plugin

[nym240]

Hi,

I was trying to use check_nwc_health plugin to monitor a device via SNPv3.

Here's the full command (im trying to list all interfaces first, just to see if the command works):
/usr/local/nagios/libexec/check_nwc_health --hostname host1 --protocol 3 --username 'user' --authprotocol sha --privprotocol aes --authpassword 'authpass' --privpassword 'privpass' --contextname '' --mode list-interfaces


but im getting below error:

CRITICAL - cannot create session object: Received usmStatsWrongDigests.0 Report-PDU with value 27 during synchronization

Maybe someone using v3 on this plugin can help me, I've been stuck with this for few days now, I cant get concrete answers on any forums I read.

Hi @nym240,

Thanks for reaching out.

You could try the suggestions from this post. It suggests using the --verbose flag and running tcpdump, to get more information.

Hi Laura,

Tried to do it but it doesnt give me anything.
I tried to use snmpwalk with the same credentials, although the auth and priv protocol is in 256. Not sure now if my command format is correct.

Hi @nym240,

Looking at the documentation on Github https://github.com/lausser/check_nwc_health and their "official" documentation http://labs.consol.de/nagios/check_nwc_health, it may not support v3. All the examples use a community string.
