SNMP V3 on snmp walk

[saherker]

We were not able to find an SNMP v3 snmp walk. Is this feature coming, or can this be added to the snmp walk feature?

The built in snmpwalk wizard should work with v3 just fine. What issues are you having? Also what version of XI are you using, and are there any updates for your wizards?

[saherker]

If we attempt to run snmp walk without a v2 community string, it fails, even though I have v3 selected. I can select SHA for auth protocol, but where can I select AES encryption?

The generic monitoring wizard is also having the same issue.

Nagios verion: Nagios XI 2012R1.6

Looks like there was a bit of missing functionality in these wizards. Attached is a corrected snmpwalk.zip you can install through Admin -> Manage Config Wizards

And an updated SNMP wizard

Looks like there is some command check logic missing from the updated snmpwalk.zip you posted.

Setting up a check with the snmpwalk wizard using version 3 authNoPriv settings on hrSWRunPath.1 produces the following error and output:

data_label problem - No data received from host
/usr/bin/snmpget -t 1 -r 5 -m HOST-RESOURCES-MIB -v 3 [authpriv] <host address omitted>:161 hrSWRunPath.1

Looking at the snmpget documentation, there are several flags missing to correctly execute a snmpget command using the version 3 protocol. The following command does produce output:

/usr/bin/snmpget -t 1 -r 5 -m HOST-RESOURCES-MIB -v 3 -l authpriv -u nagiosxi -a SHA -A <password omitted> -x AES -X <password omitted> <host address omitted>:161 hrSWRunPath.1

Can you take the $ARG1$ value for the check and the $HOSTADDRESS$ to populate the following line and try to run the fillowing from the commandline

Code: Select all

/check_snmp -H $HOSTADDRESS$ $ARG1$

Then post the output (obfuscating sensitive details)

Thanks

Sorry I lost track of this post.

We have found a differnt way to do the monitoring we were trying to accomplish with the SNMP walk check. So, unless you want to try and troubleshoot this further for your benifit, we can problaby end this thread here.
