Reports the highest number of concurrent active connections this Virtual System has recorded since counters were last reset. This peak value is what capacity planning actually sizes the connection-table limit against, since a momentary peak that came close to vsxCountersConnTableLimit is a much stronger signal of future risk than the current, possibly quiet, vsxCountersConnNum reading. Example: a tenant whose vsxCountersConnPeakNum came within 5% of its table limit during a past traffic surge is a candidate for a limit increase even if its current connection count looks unremarkable today.
