Does anyone know how i can find the messages of players who fail to join due to not whitelisted, connection error, or other and send it in chat also if someone leaves then detect the reason if it isn't themselves i want to know if its timed out, too much packets or other without checking console

So the idea is

Code (Text):

1. on connect
2. if player fails to join
3. find players fail to join message
4. send "%player% tried to join but could not join "Failed join reason/message" to op/staff
5.  
6. also
7.  
8. on disconnect
9. if player did not leave to themselves
10. find players disconnect reason
11. if disconnect reason has "kick" "ban"
12. cancel event
13. send "%player% probably did not mean to leave "Disconnect reason"

i have no clue how to do anything like this and i need at least a start on how to do this. this code is not real, but it should explain what im looking for in detail

 

its in console lmao PLUS other servers have done it
