Information on NODERED features

Guys, can anyone explain to me what this pane marked in the image herewith means and how to interpret the notifications, please?

Thank you all for your valuable input because this question arises from an existing issue where my Nodered software does not connect to the Mosquito broker. The ESP32 sensor easily connects and sends messages to the broker. However, NODERED; despite it showing that it has connected to the broker does not show any messages. Could someone spot the issue ?

Those are your config nodes. The numbers are how many nodes are using each of the config nodes.
