Host doesn't show up in "Host Availability" in Active mode (No interfaces)

[x561]

Greetings
This is my first time using Zabbix and I might be asking a question that has already been asked and answered before.

I want to run Zabbix exclusively in active mode, to reduce server load for the zabbix server.
So I have created the following host without adding any interface as I want to exclusively run it in Active mode.


Now, it shows up as "Available" under Availability in the Data Collection->Hosts page

HOWEVER
In the Zabbix dashboard, it does not show up under "Availability"

I stopped the zabbix agent2 service to see whether it shows any Trigger cuz of it or not, it does not.

So how can I check whether a host is up or not natively?

Is it that in Passive mode, host availability isn't shown?

Do I have to add an interface? But doesn't adding an interface mean that zabbix is now connecting to the agent in Passive mode so the server would be polling the agent instead of the agent polling the server? Or should I add the interface of the server running Zabbix agent. And as long as I make the Item themselves run in Active mode, then the Zabbix server would *only* check host availability passively but all the items (and triggers) would run in Active mode?

Or is the only solution here to do icmp ping to the host? But I am looking for *native* support for checking host availability and doing whatever is the correct recommended approach.

Thank you.

I just found out the Zabbix Agent Active template has "Active agent availability" item that triggers `Linux: Active checks are not available` if the host is down.


Sorry I didn't know of its existence because it takes some time for it to get triggered, 3 minutes or so. So I didn't realize existed previously.

The issue has been solved, thank you.

Question: For the host known as avm (with the visible name of avm 0), is that system running your current zabbix application?

system running in my current zabbix application meaning?

The setup is that I have a server running Docker containers for Zabbix Server, Dashboard and the Postgres database.

And then I have individual machines that are running Zabbix agent2.

Zabbix agent2 can connect to Zabbix server. The items are being populated, and I am getting triggers too.
