Using the BrightScript Profiler

Roku has a Profiler tool you can use to visualize any profiling data captured in the last session of a channel if it has profiling turned on.

To use the Roku Profiler:

1. Download and install the Profiler tool.

2. Enable profiling in your app’s manifest file. There are multiple ways you can do this:

   • Manually add the manifest components to the file; for example:

      bs_prof_enable=true
      bs_prof_sample_ratio=1.0
     

   • Use the youi-tv roku-client command to side-load the client with the required components; for example:

      youi-tv roku-client -l -s <rokuipAddr> --manifestOptions bsprof_enable=1 --manifestOptions bsprof_data_dest=network
     

     or

      youi-tv roku-client --host <localHostIPAddress>[:<port>] -s <rokuipAddr> --manifestOptions bsprof_enable=1 --manifestOptions bsprof_data_dest=network
     

     For a full description of possible Profile tool manifest component, see Roku documentation.

   Note: To save typing, you can define a separate manifest file for profiling and then use the ‘youi-tv roku-client’ CLI command with the -m option to specify it.

3. Launch the resulting bsprof_web_tool app.

   

4. Use the Profile tool to visualize the data. Select your device and start gathering data by clicking Start Profiling.
