Not so long ago dramatically increased the load on the site to the stage... nothing works, only intensive feeding resources.

The atop utility allows you to save logs that contain different server metrics. Very useful for diagnosing performance problems. Works interactively and in the background.

Installing Debian/Ubuntu

apt-get install atop

For startup enough:

service atop start

By default saving every 10 minutes, this value can be changed in the file /etc/default/stop or /etc/sysconfig/atop (variable INTERVAL).

I have already considered the issue of Analyzing how much space is occupied on the hard disk.(in Windows), on Unix\Linux this is something else, the console rules the ball there and the more you communicate the more convenient it becomes. Today I want to tell you about one of the ways to quickly find what is occupied space on the disk.

du - a standard Unix utility stands for disk usage - a standard Unix program for evaluating the occupied file space. Ancient as a mammoth:)

It is better to start with the team:

du --max-depth=1 -h /
