Monit alert - upoload byte exceeded public

Hi there,
I am confused about that message, and I can't find any doc anywhere.
CWP PRO have monit monitoring activated.
I keep receiving this email

My question is. What does "upload" means.

Does it mean the server itself is uploading data somewhere else?
Or
does it mean someone somewhere is uploading data TO the server.

Thanks.

Hi, there. That means upload rate must be less 1 GB in 1 hour. Or you have big traffic
