I build a Service Template (SNMP) for the QNAP-NAS. It works fine to get the VolumeFreeSize of the QNAP:
Now I want that I get a warning when the Volume is less than 1.5 TB and critical less than 1 TB.
How can I do that? The custom properties snmp_warn and snmp_crit reach only when the value is higher, I need the opposite.
