icmpping item

[MichaelF]

Hello,
I need to create an item using icmpping so I've read the theory (https://www.zabbix.com/documentation.../simple_checks - 11.png in the attachment) and tried to add several versions of the corresponding item (12.png) - all of my icmpping items are displayed as Not supported - why?

Thank you in advance,
Michael
