This read-only counter tracks the total number of packets sent by the system since it last booted, covering both cut-through traffic and host traffic. An admin compares packet counts against byte counts (wgSystemTotalSendBytes) to derive average packet size, helping distinguish bulk-transfer traffic from many small packets typical of VoIP or DoS-style traffic. For example, a sudden surge in wgSystemTotalSendPackets without a corresponding rise in bytes sent could indicate a burst of small packets consistent with a SYN flood.
