= On Time Measurement Findings =

Evaluation of the [http://groups.geni.net/geni/wiki/OnTimeMeasureTutorial OnTimeMeasure Experimenter Tutorial] turned up an installation problem which prevented the MySQL package from installing. After manually installing MySQL, service still did not run properly.  Started a new experiment, which also ran into problems with nodes not installing the expected packages for Root and Node Beacons, this issue was also resolved.  Was able to successfully complete the [http://groups.geni.net/geni/wiki/OnTimeMeasureTutorial OnTimeMeasure Experimenter Tutorial] and upon completion of the review the following email was sent to capture all [wiki:GIR4.1_OnTimeMeasuraments/ feedback]

== OnTimeMeasure Experimenter Tutorial Review ==

The details captured in this section were executed as part of the evaluation for the [http://groups.geni.net/geni/wiki/OnTimeMeasureTutorial OnTimeMeasure Experimenter Tutorial]. 

'''First try''': Used the instructions that made use of importing an OnTimeMeasure [http://ontime.oar.net/INSTALL/OTCDemo.rspec Rspec].

1. As instructed, requested user account at [http://ontime.oar.net/UserRegistration.php OnTime User Registration] page. 

2. Reviewed instruction for getting account, generating keys and certificate, no issue found in the instructions.

3. Using flack, create a slice and sliver using the rpsec provided in the tutorial, no issues found, so not captured here.

4. Upon completion of sliver setu-up verified the Root and Node Beacons by connecting to the host URL on port 17291.  Found that RootService had not started due to a  MySQL installation issue, which was resolved by a patch.

Note: If the RootService is not running one can kill the ''supervisord'' process and then re-invoke it by issuing the command ''supervisord'' in the directory ''/opt/OnTimeMeasure/RootBeacon'', which did not work, so rebooted to get all processes, which worked.

5. Configured the root and node beacons in the /opt/OnTimeMeasure/OnTimeControl/config.yaml, and tried to check the measurement service status. At this point ran into another MySQL access problem, and based on suggestion started a new experiment.

'''Second Try ''':  For this run through, chose the path that guides the user through manual compute resource definition.

1. Created a slice and defined sliver resources for Root and Node Beacons, as shown in tutorial.  The Node Beacon did not run as expected, there was no package installed on the nodes.
