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.
-c 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
