<ul class=" "><li class=" "><p>Aiding developers during the development of their traffic steering pipeline by providing visualization of the pipeline, and later also performance insights about the designed pipeline</p> </li><li class=" "><p>Aiding developers in pre-production environment by providing live monitoring of the performance indicators of the program on both software and hardware levels, and helping detect possible bottlenecks/critical paths so they are addressed before deployment to production environments</p> </li><li class=" "><p>Aiding administrators monitor the program in production by providing live monitoring as well as high-rate hardware counters to be used when analyzing a possible deployment/setup issue</p> </li></ul><p>The tool operates in three distinct modes,
