UPS Utility Manual

3.5.2.14 UPS Devices Monitored
This field shows the number of UPS devices that the UPS Monitor Process is monitoring (or is attempting to monitor).
The value in this field should always be the same as the value of the UPS Devices Configured field.
It can be a different
number only if the system was configured with more UPS devices than the UPS
Monitor Process is capable of
monitoring. (At present, the limit is 128 UPS devices.)
In such an unlikely case, the UPS Monitor will monitor as many
UPS devices as it is capable of, and ignore
the rest. In such a case, you could see "200 UPS Devices Configured" and "128
UPS Devices Monitored", for example.
3.5.2.15 UPS Devices Allocated
This field shows the number of UPS devices that the UPS Monitor Process has successfully
allocated through the MPE/iX
File System. (Each UPS device to be monitored must first be allocated, to give
ownership of the UPS device to the UPS
Monitor Process.)
This number should always be the same as the UPS Devices Configured and UPS Devices Monitored fields.
In the
unlikely event that some UPS device(s) can not
be allocated via the File System, this number will be less than the number
of UPS devices configured and to be monitored.
If this happens, something is wrong with the system, and corrective action
is needed. One way in which a UPS device can fail to be allocated is: a failure of the system to initialize and download
a
DTC (Datacommunications and Terminal
Controller) to which a UPS is connected will result in a failure of the File System
to "open" (allocate) that UPS device.
