This read-only counter tracks the total number of packets received by the system since it last booted, covering both cut-through traffic and host traffic. An admin monitors this counter to assess inbound packet rates and correlate them with CPU utilization spikes, since high packet rates can stress the appliance more than raw byte volume. For example, if wgSystemTotalRecvPackets climbs sharply while wgSystemCpuUtil also spikes, the admin might suspect the firewall is under a packet-flood style attack.
