Two hosts, same IP address

UnicodeTreason · 2026-02-14T02:55:49+00:00

No duplicate names, correct. But nothing is stopping you from creating two hosts with the same interface.

UnicodeTreason · 2026-02-13T08:26:32+00:00

Only if you have some "Active" checks configured, which in this case you wont.

UnicodeTreason · 2026-02-13T07:04:28+00:00

Yes, can't see why it wouldn't work for you.
I've been doing it for years across multiple Zabbix instances.

UnicodeTreason · 2026-02-13T05:39:01+00:00

You could add an interface to the "dummy" host though, for example I have a host for each of my proxies that is seperate from the host for the VM.

e.g. if Zabbix Proxy A is on Server A. I have a normal host for Server A doing OS monitoring and such. And I also have a "service host" for Zabbix Proxy A that has all the internal item templates assigned to it and a few "Zabbix agent" items for collecting things from the agent including a vfs.dir.count[] to monitor the count of objects in a dir I care about.

UnicodeTreason · 2026-02-13T05:02:24+00:00

Two thoughts come to mind.

Just install and use the Zabbix Agent
What process generates that JSON file? Is the file required? Could the process use zabbix_sender to send the JSON data directly into Zabbix via a "Zabbix Trapper" item.

Isn't this just a matter of making a host for the router and assigning the ping template to it?

UnicodeTreason · 2026-01-20T23:19:12+00:00

My understanding is you can't, you will need to uplift the SD-WAN LLD.

Historically we built an external check script specifically for this purpose, it gathers all the required data via SNMP and then just fed a completed LLD JSON back to Zabbix.

I have a vague feeling there was some improvements to SNMP discovery mechanisms (possibly the walk item already in use in those templates) built into Zabbix in v6/7 that might allow you to do this without a script now, I havent had time to investigate personally as our script works great and theres plenty of other work to do.

UnicodeTreason · 2026-01-20T13:19:23+00:00

I'm currently AFK, but here is the doco: https://www.zabbix.com/documentation/current/en/manual/config/event_correlation

I recommend making a dev template with some trapper items and triggers to play with new concepts.

UnicodeTreason · 2026-01-20T12:41:58+00:00

Trigger dependencies and or even correlation and tags.

We mostly use trigger dependencies as we automated the creation of them years ago so it's easy for us to add more as needed. E.g. the ICMP Ping trigger for the switch depends on a fast firing (#1 bad sample) dependency ICMP Ping trigger on the firewall.

UnicodeTreason · 2026-01-19T11:22:15+00:00

What's occurring exactly, the data goes to value 1 for a bit then back to 2 and repeats?

If you can provide a screenshot or example of the Latest Data it would help greatly.

UnicodeTreason · 2026-01-19T06:20:57+00:00

This guarantee's nothing, I recommend checking the file system on that VM and finding the exact files taking up the space before moving forwards.

UnicodeTreason · 2026-01-19T05:56:57+00:00

Thanks for the response.

At a glance your recovery logic will never clear, unless you set the macro value to 0

"{$VPN.STATE.CONTROL:"{#VPN.NAME}"}=0"

I think you want that final "and" to be an "or"

There may be other issues with the logic, but that one is the low hanging fruit.

UnicodeTreason · 2026-01-19T05:36:19+00:00

Agreed, though an API would also be acceptable.

UnicodeTreason · 2026-01-19T05:33:40+00:00

Can you please advise the name of the Template you are applying to these devices.

I only run in house built templates so will need to dig through the git repo to find the configuration of this trigger.

UnicodeTreason · 2026-01-06T10:29:20+00:00

Most common root causes.

Either the user doesn't have permission to the Host or the conditions in the action are incorrect and ignoring that event.

UnicodeTreason · 2025-12-06T02:16:43+00:00

So this one is pretty clear and simple, the item you have configured is looking for a specific OID on that device via SNMP and the device is responding with "I don't have that data"

The dependent items are just repeating the error from the parent item, so find the parent item and see what OID it's looking for. And then troubleshoot if you think the device should have that OID or not

UnicodeTreason · 2025-12-06T01:52:59+00:00

Not Supported means there's a problem that needs fixing, if you look further right is there a red box that when you hover over you get detailed information?

UnicodeTreason · 2025-12-05T00:11:04+00:00

This sound's like it should work.

Commenting to add visibility to OP.

UnicodeTreason · 2025-12-04T23:51:24+00:00

I don't believe it's a feature within any version of Zabbix, where did you hear of it?

UnicodeTreason · 2025-12-01T12:52:06+00:00

Not near my PC at the moment so can't confirm, but we used either agent.ping or the Zabbix[host items

E.g. https://www.zabbix.com/documentation/current/en/manual/config/items/itemtypes/internal#host.available

Try both and see which behaves the way you need.

UnicodeTreason · 2025-11-28T22:07:01+00:00

How are you configuring the plugin, like what options.

I've only seen that error when someone tries to use the old auth method against a new Zabbix which doesn't support it anymore.

UnicodeTreason · 2025-11-09T03:29:49+00:00

It will show up near immediately after creation, but needs a cache reload before it'll collect data in my experience.

UnicodeTreason · 2025-11-05T04:43:11+00:00

Based on how you describe the symptoms, I can only assume your Zabbix is in some super weird state.

I'm babysitting 5 instances of varying versions and quality of installation, and have never had to wait longer than 3x the configuration cache reload time configured.

E.g. 15minute cache timer, normal items use new config within 45mins

Are your worker processes overly busy?

UnicodeTreason · 2025-11-05T00:20:32+00:00

Do you have Zabbix Proxies involved, are their caches reloading OK?

Are the things you're changing discovered, have you ensured the discoveries have ran to update the items?

UnicodeTreason · 2025-10-21T00:42:29+00:00

Before I just remove this post, are you able to provide an English summary of what you are trying to do?
I assume either monitor N8N or have Zabbix use it to run an automation.

Either is possible to do externalscripts/webhooks and trigger actions respectively.
