CPU Load Log as Trend

[Jørn]

Use this script to log CPU load to an object. Resident script sleep time controls how often load is calculated.

Code:

data = io.readfile('/proc/uptime'):split(' ') total, idle = tonumber(data[ 1 ]), tonumber(data[ 2 ]) if prevtotal then   deltatotal = total - prevtotal   deltaidle = idle - previdle   load = math.floor((1 - (deltaidle / deltatotal)) * 100 + 0.5)   grp.update('32/0/0', load) end prevtotal, previdle = total, idle

What datatype would appropiate for this output`?
