 Specify the file on the given node where you are collecting !NetLogger log messages.  BLiPP will then check the file for new messages on the specified interval and report the collected values to the measurement store.
 
-The event type(s) for !NetLogger probes depend on what is found in the log messages.  Since they are defined by the programmer, BLiPP does not know about them until it begins parsing the log file.  Once data is available, BLiPP will update the measurement information and display the event types in the drop down next to the scheduled test.  Give it a few minutes and then refresh the page.  Once the event types appear, you can select 'Graph' and display a graph of the collected measurements from the log file.  The following exercise will ask you to use !NetLogger on your experiment node and collect the measurement data with BLiPP.
