NAME

icmpstat.d - print ICMP statistics. Uses DTrace.

SYNOPSIS

icmpstat.d

DESCRIPTION

icmpstat.d is a DTrace program to print ICMP statistics every second, retrieved from the MIB provider. This is a simple script to demonstrate the ability to trace ICMP events.

The ICMP statistics are documented in the mib2_icmp struct in /usr/include/inet/mib2.h; and also in the mib provider chapter of the DTrace Guide, found at http://docs.sun.com/db/doc/817-6223.

Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command.

OS

Solaris

STABILITY

stable - needs the mib provider.

EXAMPLES

Print statistics every second,: # icmpstat.d

FIELDS

STATISTIC: ICMP statistic name
VALUE: total of statistic during sample

DOCUMENTATION

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.

EXIT

icmpstat.d will run forever until Ctrl-C is hit.
