Is It possible to raise an alarm for a watch when the Watch status is "Unable to read attribute <attribute_name>" ?

Spectrum 10.2.x an all platform.
Yes. customize the events 0x480015 to raise an alarm and the event 0x480016 to clear the alarm.

When the watch monitored attribute is not available the watch status is " "Unable to read attribute <attribute_name>"  and the 0x480015 is being generated.
for example: 
Sep 13, 2017 7:40:17 AM EDT ..... The evaluation of watch Watch_3 failed for model xxxxxxx: Unable to read attribute SvSvcName 0x480015 System... 

Via Event Configuration you can modify the event 0x480015  to raise an alarm or with an Event Rule to trigger a new custom event and raise an alarm... 

Then you can modify the 0x480016 The evaluation of watch {S 1} succeeded for model {m}. event to clear the previously created alarm.
