<div style="font-family: Arial; color: rgb(0, 0, 0); font-size: 12pt;">I'm trying to monitor the load of some Linux servers. I've tried a number of different scripts and can't find anything with the glorious Google method. Does anyone have a working method to monitor
load on some Linux machines?<br>
