OMF » OML - Applications

Zainab needs to use "trace_oml2" for her experiments.

In the current binary on the current baseline, the src and dst MAC addresses are not strings but integers.

From the node (node30 with current baseline):

root@node30:~# trace_oml2 --version
# OML Client V2.3.9 Copyright (c)2007-2009, NICTA
# OML Protocol V1
Missing interface
root@node30:~# 

The application is run with the following command line:

env -i OML_SERVER=tcp:norbit.npc.nicta.com.au:3003 OML_EXP_ID=testing_slice-2010-09-01t14.24.36+10.00 OML_NAME=Observers  OML_CONFIG=/tmp/testing_slice-2010-09-01t14.24.36+10.00-test_app_trace_oml2.xml /usr/bin/trace_oml2 -i int:ath0 -r

The content of the XML config file is:

<omlc id='Observers' exp_id='testing_slice-2010-09-01t14.24.36+10.00'><collect url='tcp:norbit.npc.nicta.com.au:3003'><mp name='radiotap' samples='1'/></collect></omlc>

The resulting database is attached, and a quick query for a few lines with src & dst MAC returns:

[thierry@norbit ~]$ sqlite3 /tmp/testing_slice-2010-09-01t14.24.36+10.00.sq3
