Sorry for the title I don’t know how to title it better - change it if you want.
The idea is to have an zabbix raw item in one template which gathers the data. For example reads out /proc/mounts or your implementation of getting filesystems in Linux. That of course already works.
what doesn’t work is to make dependent items in multiple other templates. Currently one might make a new template and link the former one. And a host can only link this one template because otherwise there will be errors because dublicate keys for the raw item.
The use case might be that we can make a template which only discovers nfs fs/mounts out of the raw item while another template might gather xfs.
