TRACE-SUMMARY(1)

NAME
trace-summary - generate network traffic summaries

SYNOPSIS
trace-summary [options] <pcap-file>|<conn-summaries>

DESCRIPTION
This manual page documents briefly the trace-summary program.

trace-summary is a Python script that generates break-downs of network traffic, including lists of the top hosts, protocols, ports, etc. Optionally, it can generate output separately for incoming vs. outgoing traffic, per subnet, and per time-interval.

Per default, it assumes the input-file to be a libpcap trace file. If it is a Bro connection log, use -c. If input-file is not given, the script reads from stdin. It writes its output to stdout.

OPTIONS

--version
    show program's version number and exit

-h, --help
    show this help message and exit

-b, --bytes
    count fractions in terms of bytes rather than packets/connections

-c, --conn-summaries
    input file contains Bro connection summaries

--conn-version=CONN_VERSION
    when used with -c, specify '1' for use with Bro version 1.x connection logs, or '2' for use with Bro 2.x format. '0' tries to guess the format

-C, --chema
    for packets: include only TCP, ignore when seq==0

-e, --external
    ignore strictly internal traffic

-E EXCLUDENETS, --exclude-nets=EXCLUDENETS
    excludes CIDRs in file from analysis

-i ILEN, --intervals=ILEN
    create summaries for time intervals of given length

-l LOCALNETS, --local-nets=LOCALNETS
    differentiate in/out based on CIDRs in file

-n TOPX, --topn=TOPX
    show top <n>

-p PORTS, --ports=PORTS
    include only ports listed in file

-P STOREPORTS, --write-ports=STOREPORTS
    write top total/incoming/outgoing ports into files

-r, --resolve-host-names
    resolve host names

-R tag, --R=tag
    write output suitable for R into files <tag.*>

-s FACTOR, --sample-factor=FACTOR
    sample factor of input

-S SAMPLE, --do-sample=SAMPLE
    sample input with probability (0.0 < prob < 1.0)

-m, --save-mem
    do not make memory-expensive statistics

-t, --tcp
    include only TCP

-u, --udp
    include only UDP

-U MINTIME, --min-time=MINTIME
    minimum time in ISO format (e.g. 2005-12-31-23-59-00)

-v, --verbose
    show top-n for every interval

-V MAXTIME, --max-time=MAXTIME
    maximum time in ISO format
