tracestats is a libtrace tool that provides a summary of how many bytes/packets match a series of bpf filters.

Usage

tracestats [ -f | --filter bpf ]... inputuri...

Options

-f, --filter

Specifies a bpf filter to provide statistics for

Applications

Find out how much SMTP traffic is present in a trace

tracestats -f "tcp port 25" erf:trace.erf.gz

Find out how much HTTP traffic is travelling to and from the host 'kodiak'

tracestats -f "tcp port 80 and host kodiak" erf:trace.erf.gz

Compare the amount of traffic the hosts 'yogi' and 'booboo' are doing

tracestats -f "host yogi" -f "host booboo" erf:trace.erf.gz

Notes

• tracestats only produces stats across the entire trace. If you want to see stats at regular intervals, use tracertstats instead.
• Because tracestats reads the entire trace before printing results, it is not very useful for live capture formats that have no logical end e.g. int:, pcapint:. We hope to correct this in a future release of libtrace. In the interim, tracertstats will prove to be more useful for those formats.
• tracesummary is a tool that runs tracestats with a number of useful filters which may be more useful to people who want some general statistics about a trace without having to write lots of bpf filters.
