How Do You Configure the Zabbix Agent to be Active Only
-
Trying to properly configure that Zabbix Agent to only do active checks. But the documentation on this is terrible. Nothing gives a comprehensive guide to how to make that actually work.

Curious as to why you would want only active checks?
What happens if you comment out the
Server=line and leave theServerActivelines as they are? -
Clone the templates, as by default the included templates are all passive. Each item of the template has to be modified to be active
-
Here is where to make the change of an item:

Because passive checks requires going through NAT, moving to static IPs, port forwarding on a massive scale, implementing DDNS for every device, etc. Simply untenable.

hmmm we had same scenario let me pull config. Notice we put 3 servers seperate by comma like route.

Hello @Romo and @scottalanmiller !
Were you able to get active checks from Zabbix agent2?
I have seen that in the official template https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/app/docker there are 2 discovery rules with some prototype items. Only a few of them are configured as passive items, the others are configured as Dependent items. Is it enough if I change these few times from passive to active?

@matypro Hi.. to help you on this, I need to clarify two points (maybe you know that, but just in case). To enable Active Agents on Zabbix, there are some things:
- Set agents as active - this is the most important one due to this configuration enables the active communication, so to do that:
- Set ACTIVE agents and server, set the port 10051 TCP (localhost on server, and Listenport on agent)
- On Zabbix Server you will find the "Template Os Windows", (also available for Linux and Mac), so full clone it and change the name (ie. "Template OS Windows Active") and add/LInk on it the "Template AppZabbix Agent Active" which is available on your list of preconfigured templates on Zabbix server... once you do that, you´re ready to setup, actually you don´t need to setup the IP of the agent on the Zabbix server (that´s required only for Passive profile), just ensure that it containt the Agent name.
Now your Server and Agent are on active mode, you may find a world of options about the data you need to get on active mode, but some such as network, processor or memory are ready out of the box from these templates.
If you need more help just let me know
