Reports the current number of active connections being tracked in this Virtual System's own connection table. Since each virtual system has its own connection table capacity, compare against vsxCountersConnTableLimit, this per-tenant figure is what determines whether a specific tenant is approaching its own connection ceiling, something a chassis-wide view alone would hide among many healthy tenants. Example: vsxCountersConnNum for one tenant sitting at 95% of its vsxCountersConnTableLimit while every other tenant on the chassis is well under half explains new-connection failures reported by just that one customer.
