          -- This Alarm mechanism periodically takes statistical samples
          -- from variables available via SNMPv2 and compares them to
          -- thresholds that have been configured.  The alarm table
          -- stores configuration entries that each define a variable,
          -- polling period, and threshold parameters.  If a sample is
          -- found to cross the threshold values, an event is generated.
          -- Only variables that resolve to an ASN.1 primitive type of
          -- INTEGER (Integer32, Counter32, Gauge32, TimeTicks,
          -- Counter64, or UInteger32) may be monitored in this way.
          --
          -- This function has a hysteresis mechanism to limit the
          -- generation of events.  This mechanism generates one event
          -- as a threshold is crossed in the appropriate direction.  No
          -- more events are generated for that threshold until the
          -- opposite threshold is crossed.
          --
          -- In the case of sampling a deltaValue, an entity may
          -- implement this mechanism with more precision if it takes a
          -- delta sample twice per period, each time comparing the sum
          -- of the latest two samples to the threshold.  This allows
          -- the detection of threshold crossings that span the sampling
          -- boundary.  Note that this does not require any special
          -- configuration of the threshold value.  It is suggested that
          -- entities implement this more precise algorithm.
