Can you feed the tool any historical log files to build the data set?
Visualizer can build a data set using TServer, SIP Server, Interaction Server or GPlus Adapter for WFM logs. What gets lost is the power of consolidation across all those applications to see if a multi-channel agent has more than just a voice interaction and also the related configuration information. The more logs that you try to use the more processing time the Visualizer application may need to produce the data set. The true power of the application is displayed when used in conjunction with Data Collector.
