tracertstats
TRACERTSTATS(1) User Commands TRACERTSTATS(1)
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 ] [ -m |
--merge-inputs ] 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.
-c count
--count count
Output results every count packets.
-m
--merge-inputs
Treats all inputs as a single input, resulting a single unified output rather than an output for each input. Works best with traces
that are consecutive to create a single CSV, for instance.
-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
