Using atop to track your optimization results
Tuesday, January 29th, 2008Recently, I rediscovered atop. It is an excellent command-line tool (just like top) that shows some advanced statistics including disk usage and swap page faults per process. For the disk usage to work per process a kernel patch is currently required. However, even without the kernel patch if you know which processes running on your server you’ll be able to guess which is utilizing the disk more.
