Multiple snmp communities, same host

[Eduardo Tacara]

I need to monitor Cisco device with vrf, each vrf aswers with a different community, for example:

default community: abcd

vrf prod = community abdc-prod
vrf dev = community abcd-dev

This community+vrf configuration is automatic from the Cisco device.


Zabbix 4.2 is possible to configure it direct in Items or Discovery. Zabbix 6 there is no option for comminity in items.

Zabbix 4:


Zabbix 6:

Any suggestion?

Even without paid support, you can submit bugs and enhancement requests to the Zabbix bug tracker at https://support.zabbix.com

Since this was a feature in a previous version and it no longer works, a polite bug report might get them to look into adding it back.

I haven't tried this, but is it possible at 6.x to create multiple Zabbix 'host' entities that map to the same host, and then assign some SNMP items to one host and some SNMP items to the other host? I'm skeptical how well that will work, but it might be worth experimenting with it.

Where did you set that macro in v4? Host level? Template level?

What I did as a quick'n dirty solution:
- created multiple SNMP interfaces for the host in Zabbix (with different community strings per VRF, as configured on the switch)
- created per-VRF discovery rules for the host
- assigned each discovery rule the correct SNMP interface.

The only better solution I had in mind was to create the configs programmatically via Zabbix API. But I haven't had a business case for that yet so I have managed with the manually copied (and edited) discovery rules for now.

I'm open for better suggestions.

Is there a way to handle this via template somehow? Looks like a headache to set this up on every host.

Yes, I created the discovery rules in a template and attached it to all the routers that had the same set of VRFs.

Hi!

In your template, how did you manage to associate the different discovery rules with specific host interfaces? There doesn't seem to be any "Host interface" field in templates.

Sure, it's possible to change the host interfaces after applying the template, but you'd need to do that for each item prototype inside your discovery rules, which would be... Less than ideal.
