 This data can also be downloaded using "wget" command and easily visualized using a tool such as gnuplot. You can find a helper script in the tutorial package that plots they key performance data downloaded.
 
-'''Method 2:''' Alternatively, the performance data may also be visualized using ''omf-web'', OMF's web-based visualization service. It also works in concert with the result service referenced in Method 1, and makes available a variety of graph widgets to visualize live-experiment data logged using OML. Detailed documentation on the installation and usage of omf-web can be found on the [https://github.com/mytestbed/omf_web omf-web github site].

-Since this is installed on all ORBIT domains, we will only concern ourselves with defining the widget configuration required to bring up the live graphs for the performance data we are logging. Below is the contents of the simple two widget configuration file available with this tutorial package:
