Open source analytic tools support rasa chatbots

Hi, community,

I want to visualize important metrics related to our chatbot engagement with customers such as daily conversation count. I found different methods to do it.

  1. Send chatbot’s events to a BI solution and then visualize important metrics there.
  2. Use one of a rasa enterprise solution.
  3. Use a service like Dashbot

I’m curious to know about an open-source analytic tool that provides these functionalities for rasa chatbots. If anyone knows about such an open-source solution or knows about that kind of open-source solution that supports a different chatbot platform, please be kind enough to mention them here. Thanks in advance.
