    99This set of examples of the Experiments Framework explores the information contained in the HDF5 log files.  The first example, log_process_summary.py, will show at a quick summary of the the experiment, packets per rate for both Tx and Rx, Tx MPDU packet counts and number of bytes, and finally Rx packet counts and number of bytes.  The second example, log_process_details.py, goes a bit deeper and looks at the number of re-transmissions as well as the average time it took to transmit a packet.  Finally, the last example, log_process_throughput_vs_time.py, utilizes the [http://pandas.pydata.org/ pandas framework] to plot the throughput vs time of the AP and station.

    11 By default these scripts will use [wiki:../../sample_data sample data] but generally you can override this behavior with a command line argument or by modifying the *LOGFILE variable in the script.
     11By default these scripts will use [wiki:../../sample_data sample data] and you can specify any of the sample data files on the command line.  However, to process your own log files, you can override this behavior with a command line argument or by modifying the *_LOGFILE variable in the script.

     37 * To see the output from your own log file:
     38   * Run {{{python log_process_summary.py <my_hdf5_log_file>}}}
     39     * For example run: {{{python log_process_summary.py ap_two_node_two_flow_capture.hdf5}}} to see the [wiki:../txrx_log_capture two node, two flow log capture] example.
