This read-write Unsigned32 holds the higher 32 bits of a 64-bit absolute threshold value used for probe-statistics threshold monitoring, per its description, working in tandem with esaProbeStatsThresholdAbsValueLo. An administrator adjusts this when the desired threshold exceeds what 32 bits alone can represent, such as for a 64-bit performance counter. For example, monitoring a PerfCounter64-based error count in the billions would require setting a non-zero esaProbeStatsThresholdAbsValueHi alongside the lower-order bits.
