Templates for SNMP - help in configuration | Zabbix 7.0

[ppuzicki]

Hello everyone.

I'm new in the Zabbix world and I'm just starting my adventure with this system.
I have a request for help in modifying one of the original templates.

I would like to modify the "D-Link DES_DGS Switch by SNMP" template, so that the rules of discovery will work.
As an example, I will give a rule called "FAN Discovery".
In the original configuration of the template, I found such OID entries:
Discovery rule
SNMP OID: discovery[{#SNMPVALUE},1.3.6.1.4.1.171.12.11.1.7.1.2,{#STATU S},1.3.6.1.4.1.171.12.11.1.7.1.3]


Item prototype
SNMP OID: 1.3.6.1.4.1.171.12.11.1.7.1.3.{#SNMPINDEX}


I have a D-LINK DGS-1510 switch and I managed to find the correct OID for fans:

Based on the specific OID, I modified the template as below:
Discovery rule
SNMP OID: discovery[{#SNMPVALUE},1.3.6.1.4.1.171.14.5.1.1.2.1.3.1.7,{# STATUS},1.3.6.1.4.1.171.14.5.1.1.2.1.4.1.7]
Item prototype
SNMP OID: 1.3.6.1.4.1.171.14.5.1.1.2.1.4.1.7.{#SNMPINDEX}

Unfortunately, despite the change, I don't see data about the fan


I noticed the same thing that I don't have data on the switch temperature - Temperature Discovery:
Discovery rule
SNMP OID: discovery[{#SNMPVALUE},1.3.6.1.4.1.171.14.5.1.1.1.1.4.1.1]
Item prototype - I don't understand this entry in the template
SNMP OID: 1.3.6.1.4.1.171.12.11.1.8.1.2.{#SNMPINDEX}

SNMPwalk:


Tell me on the example of these 2 things how to correctly configure the templates.
Thank you very much in advance.

Best regards
Pawel

Hello Hello,
I will try to share my little experience with you.

I don't have confirmation, but from my tests, it seems that from the Zabbix interface, it does not perform snmpwalk but snmpget instead.
Therefore, you will need to add a .0 at the end of your OID (Example: 1.3.6.1.4.1.171.12.11.1.8.1.2.0{#SNMPINDEX} if you want 1.3.6.1.4.1.171.12.11.1.8.1.2.{#SNMPINDEX}).
Secondly, do not modify the base templates, clone them instead, which will always provide you with a reliable base.

Afterwards, I would advise you to create a simple item (without macros or defined parameters) to test that you are indeed collecting the latest data from your OID.

Best regards,
Lucas
