While handoff queues are the ideal way to monitor from a capacity perspective, it may be useful and/or interesting to monitor the throughput as well.
For many providers, the monitoring of throughput is done on the Hypervisor and is outside the scope of the Gateway.
For providers who want to monitor on the Gateway, the following example illustrates how to get the RX and TX byte counts, to make delta calculations over a period to measure the throughput.
vcadmin@vcg34-1:~$ sudo /opt/vc/bin/getcntr -c dpdk_eth0_pstat_ibytes -d vcgw.com 1895744358 vcadmin@vcg34-1:~$ sudo /opt/vc/bin/getcntr -c dpdk_eth0_pstat_obytes -d vcgw.com 1865866321 vcadmin@vcg34-1:~$ sudo /opt/vc/bin/getcntr -c dpdk_eth1_pstat_ibytes -d vcgw.com 33233362 vcadmin@vcg34-1:~$ sudo /opt/vc/bin/getcntr -c dpdk_eth1_pstat_obytes -d vcgw.com 29843320
The actual throughput capacity might vary based on the number of connected Edges, encryption mix, and average packet size. The handoff queues provide a clear picture of the Gateway performance relative to its capacity.
For supported value of maximum throughput, refer to the VMware SD-WAN Performance and Scale Datasheet published at the Partner Connect Portal. To access the datasheet, you must log into the Partner Connect Portal using your Partner credentials (username and password).
