In my project I would like to have everything I print to the serial ( Serial.print), to be send to some text file on the internet so that i can keep an eye from remote places on whats going on with my arduino and also for debugging purposes I am using a sim800l module.
Can anyone please help me as I don't have to much experience with internet, http, ect.
You have a very tough problem unless you have had experience. For starters simply have all print to separate local files. Then have all print to a local file then upload that file. You might want to look at some home automation software, they may have that feature in some of them. A Raspberry pi would be a great intermediate device. Also realize you can put each unit on the internet as a seperate server and then access them independently with either an Arduino or Raspberry pi.
Good Luck & Have Fun!
