How to reset server_netstat counters?

Hi there

Anyone know how to reset server_netstat counters?

Basically I want to find out retransmit % of interface we use for archiving. So shut down that interface for a moment, reset the netstat counter, run server_netstat server_2 -s -p tcp should give me retransmit % for all other infaces. Then compare that % with % of activated archive iinterface when running task should give hint if there's lot of retransmissions if acrhiving if.
