PPPoE vs Hotspot --> log

Dear,

I am configuring the error messages that are returned by the radius and are displayed in the log mikrotik, but I’m using the following doubts:

  1. Why is the hotspot log is displayed with:

    • Hotspot, info, DEBUG
    • As can be seen in this image: http://prntscr.com/6qr4lf
    • And I can return a custom message returned by radius.
  2. PPPoE in the log is displayed:

    • Pppoe, ppp, INFO
    • As can be seen in the image: http://prntscr.com/6qr4lf
    • And I can NOT display the message returned by the radius (only if I set in system / logging / add / radius = memory, but returns a lot of garbage and I just want to display the message returned by radius, as well as work in hotspot)

someone can help me.

thank you all.
