NAME

tracertstats - perform simple filter based analysis on a trace

SYNOPSIS

tracertstats [ -f | --filter bpf ] [ -i | --interval interval ] [ -c | --count count ] [ -o | --output-format csv,txt,png,html ] inputuri...

tracertstats -H|--libtrace-help

DESCRPTION

tracertstats takes a list of bpf expressions and outputs the number of packets and bytes that match that expression every interval seconds, or count packets.

-f bpf-filter

--filter bpf-filter Add another "bpf filter"

-i interval

--interval interval Output results every interval seconds.

-i count

--count count Output results every count packets.

-o format

--output-format format Selects the output format

txt

Human readable text. This is the default output format which provides output easily understood by a human. This format has the disadvantage that it takes up quite a bit of horizontal space.

csv

Comma Seperated Values. This is suitable for further analysis in a spreadsheet, or other program.

png

PNG Graphic. Produces a fairly incomprehensible png graph. This relies on gdc being available at compile time.

html

This produces output suitable for display to a human in a webbrowser.

EXAMPLES

 tracertstats --filter 'host sundown' \
         --filter 'port http' \
         --filter 'port ftp or ftp-data' \
         --filter 'port smtp' \
         --filter 'tcp[tcpflags] & tcp-syn!=0' \
         --filter 'not ip' \
         --filter 'ether[0] & 1 == 1' \
         --filter 'icmp[icmptype] == icmp-unreach' \
         --output-format html
