#!/usr/bin/ksh # # tcptop_snv - display top TCP network packets by process. # Written using DTrace (Solaris Nevada) # # This analyses TCP network packets and prints the responsible PID and UID, # plus standard details such as IP address and port. This captures traffic # of newly created TCP connections that were established while this program # was running. It can help identify which processes is causing TCP traffic. # # WARNING: This script may only work on Solaris Nevada and OpenSolaris # of the late 2007 vintage, since it uses the fbt provider to trace the raw # operation of a specific version of the kernel. In the future, a 'stable' # network provider should exist which will allow this to be written for that # and subsequent versions of the kernel. In the meantime, check for other # versions of this script in the /Net directory, and read the # Notes/ALLfbt_notes.txt for more background on fbt. # # $Id: tcptop_snv,v 1.1.1.1 2015/09/30 22:01:07 christos Exp $ # # USAGE: tcptop [-Ch] [-j|-Z] [interval [count]] # # -C # don't clear the screen # -j # print project IDs # -Z # print zone IDs # # FIELDS: # UID user ID # PID process ID # CMD command # LADDR local IP address # RADDR remote IP address # LPORT local port number # RPORT remote port number # SIZE packet size, bytes # load 1 min load average # TCPin TCP inbound payload data # TCPout TCP outbound payload data # ZONE zone ID # PROJ project ID # # SEE ALSO: tcpsnoop # # COPYRIGHT: Copyright (c) 2005, 2006 Brendan Gregg. # # CDDL HEADER START # # The contents of this file are subject to the terms of the # Common Development and Distribution License, Version 1.0 only # (the "License").
