Server Usage Meters

[jyeung]

I've seen "server usage meters" that show, for example, the number of downloads occuring on an FTP server at a given time.

How can that be created in PHP?
I've attached a file to illustrate what I mean.

Thanks.

If you are on a linux box you can use 'free' to get memory usage, and there are some other commands that you can use to get various other information. You can then put this information into a Round Robin Database (RRD) using rrdtool from www.rrdtool.com and you can then uses scripts to generate a .png image.

Hope this helps
