udpstat.d - print UDP statistics. Uses DTrace. udpstat.d udpstat.d is a DTrace program to print UDP statistics every second, retrieved from the MIB provider. The UDP statistics are documented in the mib2_tcp struct in /usr/include/inet/mib2.h; and also in the mib provider chapter of the DTrace Guide, found at http://docs.oracle.com/cd/E23824_01/html/E22973. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris stable - needs the mib provider.
