cmAlarmRisingThreshold is a read-write integer setting the upper threshold that, when the sampled statistic crosses upward past it, causes the alarm entry to generate a single event. An administrator sets this to the value that represents an undesirable high level for whatever variable cmAlarmVariable is monitoring. For example, an operator monitoring an error counter via this alarm mechanism would set cmAlarmRisingThreshold to a value indicating a problematic error rate, triggering notification once it's crossed.
