The HDD KPI gives the cost for the hardware hdd with the ACTIVE state.
The hdd is considered active when it belongs to a started hardware instance. If the hardware server is stopped, the hdd is treated as a passive one.
The hdd cost depends on its size.
The value display colour indicates the changes in the KPI value according to the following scheme:
- Grey: the value didn't change during the last seven days
- Red: the current value is the maximum one for the last seven days
- Yellow: the current value is the minimum one for the last seven days
- Green: the current value is in a "normal" scope, i.e., it does not reach neither maximum, nor minimum point
