    186186=== Retrieving Results === 
    187187 
    188 The experiment script generates a lot of data that contains not only results, but also information useful for debugging. This detailed output of the experiment along with iperf's output are aggregated on the console in a log file: /tmp/''Experiment ID''.log 
     188Data is collected during the experiment and pushed to an OML server running on the domain's console and is identified using the ''<Experiment ID>'' indicated during the initiation and conclusion of each experiment. This ID is important, as it is used to recover experiment results and even view them in real-time. (Server names vary with test beds. This server name is specific to ORBIT.) 
     189 
     190To recover experiment data to the local machine, and using the experiment ID: 
     191 
     192{{{ 
     193wget "http://oml:5054/result/dumpDatabase?expID=<your_experiment_ID>" -O myDatabase 
     194}}} 
     195 
     196 * If the experiment ID contains non-alphanumeric ASCII characters, it is necessary to escape each of them using "%" followed by the ASCII code. 
     197 
     198You're almost done. In order to get SQLite to recognize the database, it first must be told that the information '''is''' a database.  
     199 
     200{{{ 
     201sqlite3 -init myDatabase myDatabase.sq3 
     202}}} 
     203 
     204You can also view the results in a web browser by visiting the following URL: 
     205{{{ 
     206http://console.sb4.orbit-lab.org:5054/result/dumpDatabase?expID=<your_experiment_ID> 
     207}}} 
     208

     211The experiment script generates a lot of data that contains not only results, but also information useful for debugging. This detailed output of the experiment along with iperf's output are aggregated on the console in a log file: /tmp/''<Experiment ID>''.log 
    189212 
    190213For this example, the file would be: /tmp/default_slice-2016-05-26t10.05.35.243-04.00.log 
     
    252275=== Final Observations ===

    254 You have now, hopefully, succeeded in executing the experiment script in this tutorial. Try to run this experiment again but with more client nodes. Additionally, if you are trying this tutorial on the ORBIT grid, try using nodes in different locations to see those effects on performance.
