You can use 'top' in batch mode or the 'ps' command.

An easy way to send it to a browser is to use the netcat tool which can listen on a socket and sends the output of any program (here: 'top') to the connecting client. The standard port for http would be 80, but to listen on it we needed to be root, so we take 8000 instead for this example:

nc -l -p 8000 -c 'top -bn1'
(listen on TCP port 8000 and send the output I would have gotten when I had typed 'top -bn1' to the first client connecting)


A more sophisticated way to do this would be setting up a http webserver which either uses CGI to call the top command when it's explicitly requested by the browser (make sure the client can't execute arbitrary commands) or PHP to call this command.
