Cannot Add Windows Active and IIS Active Because of Overlapping Key

[techmattr]

Cannot inherit item with key "zabbix[host,active_agent,available]" of template "IIS by Zabbix agent active" to host "ServerName", because an item with the same key is already inherited from template "Windows by Zabbix agent active".

When I try to add the IIS by Zabbix agent active to my host which already has the Windows by Zabbix agent active or if I try to add them at the same time I get the above error.

I think it's due to both templates having the same host availability check. I tried disabling the item in the IIS template but that did not work. I tried deleting it and it says I cannot delete an inherited item.

So how do I monitor IIS items on a Windows server?

Ubuntu 22.04 / Zabbix 6.4.4 / Agent 2 - 6.4.4

So, I had to delete the "IIS: Active agent availability" item from the IIS by Zabbix agent active template rather than just disable it. Once I did that I was able to add it to the host. I recently upgrade from 6.2.2 to 6.4.4. This wasn't an issue in 6.2.2.

If I understand correctly your IIS by Zabbix Agent inherits from a template with a Zabbix agent active check? (Since you get the message cannot delete an inherited item)
Can you remove this inheritance?
