For any Linux system administrator its important to monitor the disk-usage of the servers and stay assured that it doesn’t reach its 100 % capacity and give rise to issues for the clients hosted on it. Therefore, as a part of routine check, the administrators need to monitor the disk space regularly.

The following command is used to help check the disk space of the entire server :

root@server# df –h

If you believe that only a particular partition consumes a lot of disk-space and you wish to investigate the folder under that partition is using it, the following command can be used:

root@server# cd /var

root@server# du –sh *

This command will show the size of every directory under the /var partition.
