Filter out Network Discovery with no light levels

[dmburgess]

So I have successfully created a item that discovery at the network level creates a RX light level for SFP interfaces.. The issue is that it is getting created on any and all interfaces even ones that dont' support that vairable. I get "SNMP error: (noSuchName) There is no such variable name in this MIB" as would be normal for a ethernet interface or bridge, but the ones with RX light levels come up.

What I need to do is tell it if it can't find a value, then don't create the item. How do I do that?

Overrides https://www.zabbix.com/documentation...overy#override

No override section in the item

Its not under "item prototype". It is separate tab under discovery itself... Hopefully you have at least version 5.0, where overrides appeared.

Ok, i found the overrides, currently running v5.4.8, but it is not available, not a blue button to click, its just grayed out.

I think you are trying to do it directly on host. You should do it in template.

By any chance are you using SNMP v1? Try switching the host interface to SNMP v2.

How is that going to help?

SNMPv1 cannot work with 64bit counters. These are used for transferred data on network interfaces (ifHCInOctets, ifHCOutOctets, ...).

Yes, but question was about filtering out interfaces, for which not to create items.. It has nothing to do with data itself..
