    12 The goal of this exercise is ...
     12The goal of this exercise is to configure BLiPP (Basic Lightweight Periscope Probes) and enable active measurements within your slice.  An example !NetLogger script will be used to generate data that will be collected with an active BLiPP probe.

     15=== The role of BLiPP ===
     16
     17BLiPP is a measurement agent that runs on every GEMINI experiment node within your slice.  Through a web interface and/or command line, you can configure BLiPP to collect both passive and active measurements from the given node.  BLiPP retrieves its configuration from a central information store known as UNIS, the contents of which we update through the configuration interfaces.  BLiPP will then store measurement data to a measurement store (MS) running on the GEMINI global node within your slice.

     20=== Access the BLiPP configuration page ===
     21
     22From the GENI Desktop page, click on the [[Image(launcher.png)]] and then select 'GEMINI GN' from [[Image(launchermenu.png)]].  Select 'Open PS Config' from the new GN window: [[Image(psconfig.png)]]
     23
     24You should then see a page similar to the below image.  Select 'Schedule BLiPP Tests' from the menu.

    16 To use !NetLogger ...
     32!NetLogger is a set of software tools that can be used to log application events and perform analysis and debugging of the collected log data.  The python netlogger tools and libraries are installed on your slice nodes by default with GEMINI.
