Template cannot be linked to another template

[toypatrick]

I am trying to add the zabbix agents to the server and assigning the template.And its erroring out can you tell me the fix.
I have to add multiple servers to zabbix server with OS monitoring.

Please tell me exactly what kind of error is occurring.
If it is an error that the item keys are duplicated, please create a template that does not duplicate item keys.

Can you let me know how to create a duplicate item keys that can be mapped to all the new servers.
Basically looking at monitoing the OS related and network related on the servers.. I am newbie to zabbix learning from scratch.

Multiple templates with duplicate item keys can not be linked to the same host. Please divide the template for OS or application so that it does not duplicate.

Specifically, what items are specifically duplicated items?
What kind of template are you trying to link?

You should be having a "host" for each Zabbix agent. Then, link each host ONLY to "Template OS <NAME>" and you should be fine.

Can you let me know how do we do that .. I am newbie to zabbix

Here you go: creating a host. It has instructions for both, creating a host and linking a template to it.

In the screenshot are three templates.
This message is abou that some of those three templates already has linked one of those two.
If those templates are standard zabbix OOTB templates Template OS Linux already is linked to the Template App Zabbix Agent and this why you see this message
This is not a zabbix bug.
