TRACERTSTATS(1)

NAME
tracertstats - perform simple filter based analysis on a trace

SYNOPSIS
tracertstats [ -f | --filter bpf ] [ -i | --interval interval ] [ -t | --threads max ] [ -c | --count count ] [ -o | --output-format csv,txt,png,html ] [ -m | --merge-inputs ] [ -N | --nobuffer ] [ -d | --report-drops ] 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.

-t max
--threads max
    Use max packet processing threads. The default is 4 threads, but adding more or less threads may improve performance.

-c count
--count count
    Stop after processing this amount of packets. Note that this is only a lower bound as this is only evaluated once per thread per interval.

-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.

-N
--nobuffer
    Disable internal packet buffering in libtrace. If the packet rate is very low (i.e. < 10 packets per interval), set this to ensure that tracertstats is more likely to print results in time with the interval rather than producing bursts of output for multiple intervals at a time.

-d
--report-drops
    Include columns with the number of packets that were either dropped by the capture process or went missing between the capture process and this tracertstats instance. The numbers displayed are CUMULATIVE, as they are pulled directly from the libtrace statistics API.

-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 smtp' \
	--filter 'tcp[tcpflags] & tcp-syn!=0' \
	--filter 'not ip' \
	--filter 'ether[0] & 1 == 1' \
	--filter 'icmp[icmptype] == icmp-unreach' \
	--output-format html
