[wiki:WikiStart Orbit] > [wiki:Documentation/Athstats Athstats] > FAQ = Athstats FAQ = == General == === What is Athstats? === Athstats is a C application which runs in Unix/Linux environment: ''/usr/bin/athstats-oml''. It takes two arguments, an interface to query and an interval period (between successive queries) in milliseconds. For e.g. ''/usr/bin/athstats-oml --interface ath0 --interval 100'' implies that this application will query the interface ''ath0'' every 100ms. Note that this application will run as fast as the kernel allows any user-space process to (going below 10ms may not make sense). === Is Athstats free software? === Athstats is open-source software and can be downloaded by everyone. However, by default, it is supposed to be used in the ORBIT testbed to take advantage of Orbit measurement framework (OML). === How can I install it? === The installation is simple. On any node of Orbit Testbed, execute the following commands {{{ apt-get update apt-get install athstats-oml }}} A binary file "athstats-oml" will be installed under /usr/bin/. === Where do I get the source code? === For orbit developers, latest sourcecode is part of the madwifi driver code. It can be checked out from SVN as follows: {{{ svn co http://svn.orbit-lab.org/svn/orbit/madwifi/trunk/ madwifi }}} Inside this directory, the source code is under tools: athstats-oml.c. For all other questions, please refer to the [wiki:Documentation/OTG/FAQ OTG FAQ] and the [wiki:Documentation/OML/FAQ OML FAQ]. === Are there any dependencies? === This tool requires the madwifi driver and experimenters are encouraged to use the version on the baseline image. This version contains a corrected update for the ''number of frames successfully transmitted'' field. It also requires the latest [wiki:OML OML] libraries. They can be installed using the apt-get utility as ''apt-get update; apt-get install liboml-client;''.
