SNMP not working (version: 201908050337)

Hello there,

I try to monitor my VyOS with Zabbix, but not get any data.

If i run:

show snmp mib ifmib

I get this:

lo:     ifIndex = 1
        ifAlias = lo
        ifDescr = lo
eth0:   ifIndex = 2
        ifAlias = OUTSIDE
Traceback (most recent call last):
  File "/usr/libexec/vyos/op_mode/snmp_ifmib.py", line 126, in <module>
    print('\t{0}'.format(show_ifdescr(i)))
  File "/usr/libexec/vyos/op_mode/snmp_ifmib.py", line 82, in show_ifdescr
    vendor = string[3]
IndexError: list index out of range

Here my SNMP settings:

set service snmp community public
set service snmp community routers authorization 'ro'
set service snmp community routers client '192.168.31.105'
set service snmp contact 'xy@gmail.com'
set service snmp location 'city'
set service snmp trap-target 192.168.31.105

Do you query it directly on the vyos host or from 192.168.31.105?

i try it on the vyos.

What if you’ll do snmpwalk from your zabbix server to that VyOS?

@Vamp can you provide full interfaces configuration? I think problem may be with interface descriptions.
show configuration commands | strip-private | match inter
And also provide please output of commands

sudo cat /sys/class/net/eth0/device/vendor
sudo cat /sys/class/net/eth0/device/device

/usr/bin/lspci -mm -d RETURNED_VALUE_VENDOR:RETURNED_VALUE_DEVICE

/usr/bin/lspci -mm -d 0x1af4:0x0001

Can you show output this command?
/usr/bin/lspci -mm -d 0x1af4:0x0001

It not show anything.

What HW you have got? Is it VM?
Show please command output sudo lspci -v
I created task in phabricator https://phabricator.vyos.net/T1575.

Yes, it is a VM.

Can you try next rolling release? I will waiting feedback from you

Now is good :slight_smile:
