This will return the type of alarm that has the highest priority
(PRTYPE) and the priority of that alarm (CRIT)

PRTYPE can have values:
0 = no active alarms
1 = high absolute
2 = low absolute
3 = high-high
4 = low-low
5 = high deviation
6 = low deviation
7 = rate alarm
8 = BAD alarm
9 = state alarm

You may have to interpret which alarm is actually active.  For example,
a PID block can alarm the measurement AND the output.  So a PRTYPE of 1
or 2 will not tell you whether you have a measurement or an output
alarm.
PRTYPE 3 & 4 only pertain to measurement because there is no high-high &
low-low alarm for output.

A limitation is that it will not show alarms of lesser priorities in the
same block.  So, an measurement alarm of priority 1 will "mask" a
deviation alarm of priority 2.

You can get more information with -mALMSTA:%8x ... this contains all the
information about active alarms, including PRTYPE and CRIT.
If you'd like to know which alarms are configured in a block, then look
at -mALMOPT:%8x These packed boolean variables are full of information,
but they require some deciphering to understand.  Using boolean masks
can screen out information you don't need.

As has been mentioned before, there is an alarm documentation script on
the cassandra website.  I have not used it, but others recommend it.
