Running a chat bot requires some caring, in particular you're never done training it.

A good habit is to inspect the chat bot log searching for user sentences that were not recognized by the bot and then update the parsers Listen node, RiveScript node, etc) in order to support it.

Log filename

In RedBot every platform receiver can log the conversation to a file, it looks like

The first string is the chatId followed by the name (if available). Then the symbol > means it's an inbound message (from user to the chatbot).

There is also the Log node that produces a log string for every message that can be manipulated inside Node-RED (in case for example the log string should be sent to an external service).
