Hi!
I'm using Zabbix 6.0 with template Net Cisco IOS SNMP for monitoring Cisco Catalyst 4500 platform.
I need remove of unnecessary items, for example:
Because I have too much vlan interfaces on this switch:
I need monitoring interfaces, such as TenGigabitEthernet, GigabitEthernet, Port-channel.
I created regex for filtering Vlan interfaces and I used several ways to set it:
1. Template Net Cisco IOS SNMP -> Macros
{$NET.IF.IFNAME.NOT_MATCHES} add ^*Interface VLAN*$
(^Software Loopback Interface|^NULL[0-9.]*$|^[Ll]o[0-9.]*$|^[Ss]ystem$|^Nu[0-9.]*$|^veth[0-9a-z]+$|docker[0-9]+|br-[a-z0-9]{12}|^*Interface VLAN*$)
2. Template Net Cisco IOS SNMP -> Macros
{$NET.IF.IFNAME.MATCHES} I changed the value of ^.*$ to (^TenGigabitEthernet1/[1-8]$|^GigabitEthernet2/[1-9]$|^GigabitEthernet2/[1-2][0-9]$|^Port-channel*$)
3. Host -> Discovery -> Template Module Interfaces SNMP: Network interfaces discovery -> Filters
{#SNMPVALUE} matches (^TenGigabitEthernet1/[1-8]$|^GigabitEthernet2/[1-9]$|^GigabitEthernet2/[1-2][0-9]$|^Port-channel1$)
But that didn't solve the problem - LLD mechanism even stopped finding interfaces.
Tell me please, where I made a mistake - in the regex or in the logic of actions?
P.S. Sorry, my English isn't very good
