Well I have made that, which seems to work alright. I set it to use the 1 minute average but the 5 and 15 minute averages can be used by setting $load[0] to $load[1] and $load[2] respectively. The only problem I am having is when I put this into a custom php block it distorts the page badly. Any help with this from others would be great.
