Hi Faiz, the more important things are about database and performace. If you are going to work with NDOUtils for example and MySQL, the best option is to create a new and independent mount point depending on the data retention that you need. Then /var/lib/mysql could be a good option. For performance, if you are going to work with pnp4nagios for example, a good option is an independent mount point for /var/lib/pnp4nagios. And for global configuration, you can create the following for example: 250MB - /boot (out of the LVM) LVM XXX - swap (depending on your requirements) 2GB /tmp 10GB /usr 8GB /var 4GB /home (it depends on that you want to do) XXX /opt (if you don't need more "external" software, probably you don't need it with a big reserve) 2GB / 50GB /var/lib/mysql 30GB /var/lib/pnp4nagios Also, if you are going to work with SVN to save the .cfg files versions, you probably need a new mount point for this to separate it. This is a example, it depends on each time. If you can, separete the important things in different mount points and maintain an standard operating system partitioning.

What is the recommended partitioning scheme in Linux (ie Redhat) suitable for Nagios implementation? How much percentage for /, 40% for /var or what not. Please advice.
