Figuring out the automatic discovery of network devices

[skym]

Hi there,

I'm running Zabbix version 5.0.1, and proxy version 5.0.1.
I'm trying to setup automatic discovery of network equipment of different manufacturers and filter the adding and automatic linking of template by the use of SNMP OID discovery check and if it contains the manufacture's name.


Discovery action rule:
Discovery check equals Automatic discovery of network devices: SNMPv2 agent (161-162) "1.3.6.1.2.1.1.1"
Received value contain <manufacturer>

Operations:
Add host
Add to host group
Link to template

I did check the logs, and there's nothing about it so I'm at a lost how you're supposed to get it to automatically do it?

Think that you miss your discover rule in the actions part
In actions

Discovery rule equals Your discover rule
Received value contains Your Value
Discovery status equals Up
Service type equals SNMPv2

Operations
add host to group
Link template

That should do the trick

Which action do you mean or do you just mean that one condition is missing which is why it's not working? In Trigger actions, Discovery actions, Autoregister actions or Internal actions?

in Discovery actions

in Discovery actions

It didn't fix the issue, still not doing it automatically.

I'm still stuck at this.. The devices are discovered, but not added.

Could you show us your discovery rule ?

What happens if you change the type of calculation to simple "and" instead of custom?

[skym]

That does absolutely nothing.

Ok just wondering as I have basically the same discovery rule, doing the same checks and applying the same actions. Only difference is that mine is just an AND rule, thought it may be some kind of bug with the way the custom rule was processed.

skym how does your network discovery look? Have you actually enabled network discovery under Configuration -> Discovery for your network segment?

You can check the status of discovery under Monitoring -> Discovery, here is some more documentation

It sounds more like the actions are not executed. Have you checked with snmpget from Zabbix Server if you are getting the correct value?

Discovery is working ish, I'm not sure if it's just the pinging part that works, but snmpget does get the right values, and discovery tab (in Monitoring -> Discovery) shows the devices.

P.S The proxy is the only one with access to the devices, and I have checked that snmpwalk works from it.

You can add some arbitrary Discovery Action ie. that executes "echo test" on Zabbix server. Then you can see in Reports -> Action Log if the action was executed. If it's not executed you probably have something wrong in discovery conditions, strip it down and find what's breaking it until you see the remote command action being logged. Another thing is that your uptime has to be 10min, for testing purposes you can remove it.

I already have a kind of a test action, as it's supposed to send me an email, but there's nothing in action log for the past day nor have I gotten an email.

I would suggest you to review your conditions thoroughly, maybe there is a mistake somewhere, try simplifying it and adding more checks on it after you are sure that it works

It is really simple already. If I don't have a ping as a check, none of the devices are discovered (Show up in Monitoring -> Discovery) even though I can use snmpwalk and check that my OID I'm using is valid so I don't really know what's the issue with it?

There's basically two checks, both of which are SNMP and I have checked that both of my OID's are valid with snmpwalk.

Any ideas people? I'm still stuck.
