If a FAST LTA system reported its total Silent Cubes capacity via SNMP but an empty value for the used capacity, the service Fast LTA SC Capacity Total crashed with ValueError: invalid literal for int() with base 10: ''.

The service now goes to UNKNOWN and shows the values it received, for example Cannot parse capacity: got total '200021140045824', used '' (expected integers).
