    28 After the experiment, the OML-instrumented peer will send the measurement results to iRODS using the {{{iput}}} command.
     28After the experiment, the OML-instrumented peer will send the measurement results to iRODS using the {{{iput}}} command. Inside iRODS, we'll use the iRODS web browser to visualize the results of our experiment.

     30The measurement database is organized as a series of key-value-wrid triples. Each {{{key}}} defines a kind of measurement (e.g., RTT or estimated available bandwidth) and each {{{wrid}}} defines a measurement source (e.g., video sender, audio receiver, bandwidth estimator).
     31
     32To visualize these measurements, we'll open the {{{sq3}}} file from our experiment in iRODS and click on the '''plot''' tab. From here, we'll be able to set up our visualization.

     34For example, we can create the following plot, which shows the round trip time in milliseconds measured by WebRTC:

     39There are many other metrics available - try plotting with the following keys:

     41 * googFrameRateReceived
     42 * googJitterReceived
     43 * packetsLost
     44 * googAvailableReceiveBandwidth
