Sorry, my question is maybe stupid. I do not understand default trigger expression for free space in Template VM VMware Hypervisor.
Problem: {Template VM VMware Hypervisor:vmware.hv.datastore.size[{$URL},{HOST.HOST},{#DATASTORE},pfree].min(5m)}<=90 and {Template VM VMware Hypervisor:vmware.hv.datastore.size[{$URL},{HOST.HOST},{#DATASTORE},free].min(5m)}<=0
Why is there a second part of expression - free space <=0? I think it never could be true if I have some little free space on datastore. Who can explain it, please?
