    106106To create sliver, you can follow either "Create Sliver by Importing RSpec file" in Section 2.3.1 below or "Create Sliver from Scratch" in Section 2.3.2 below.
    107107
     108In either case, at least 3 nodes will be created. One is called root beacon, which creates database tables and configuration files, and generates measurement schedules for node beacons. Root beacon also collects data and provides dashboard visualization. Others are called node beacon, which installs tools that measure network and runs measurements based on a schedule.

     152The RSpec file specifies three nodes.
     153
     154One node has name ROOT. It will automatically download {{{http://ontime.oar.net/INSTALL/OTCRootInstall.tgz}}} into {{{/tmp}}} folder and run Root Beacon installation command {{{"sudo sh /tmp/ontime_software_install.sh otm_slice_password"}}}.
     155
     156('''Note:''' You can replace "otm_slice_password" with your own password.  The password will be needed to use OnTimeMeasure later in this tutorial. (i.e., you should use the same password for config.yaml file in [wiki:OnTimeMeasureTutorial#a3.1ConfigIPaddressandpassword section 3.1] and database password in [OnTimeMeasureTutorial#a4.2Configuration section 4.2]))
     157
     158The other two nodes have name NODE1 and NODE2 respectively. They will automatically download {{{http://ontime.oar.net/INSTALL/OTCNodeInstall.tgz}}} into {{{/tmp}}} folder and run Node Beacon installation command {{{"sudo sh /tmp/ontime_software_install.sh"}}}.

     330You will find the status of collector is "Initializing...". It will changed to "OK" when you later add measurement tasks and start the measurement service.
     331
    284332=== 3.3 Manage Measurement Tasks ===
    285333
    286 "task_manage.py" manages the measurement tasks (i.e., requests). Edit measurement.yaml to configure tasks.

    288 '''NOTE:''' You may need to modify the node names if you are not using node1, node2, etc. as node names)
     334"task_manage.py" manages the measurement tasks (i.e., requests). Edit measurement.yaml to configure tasks. For details, please reference [wiki:OTM-Control#a4.2Managemeasurementtasks OnTime Control User Manual]

    307355
     356Run command "service_status.py" to verify whether all the components of the measurement service are functioning correctly.

    313364 
    314365=== 3.6 Query Measurement Results ===
    315366
    316 You may need to wait a while for measurement data to start appearing in the Root Beacon database for query. The wait time depends on how you configure the measurement schedules in the measurement.yaml file.
     367You may need to wait a while for measurement data to start appearing in the Root Beacon database for query. The wait time depends on how you configure the measurement schedules in the measurement.yaml file. You will get some measurement results within one minutes, but some measurement task may need half hour to be scheduled to avoid the measurement conflict.
    317368
    318369You can access Root Beacon through port 17280 in your web-browser (i.e., http://pc355.emulab.net:17280/) to check all the measurement data generated already in measurement dashboard.
