i saw many of you came and asked how to see the usage of ram, cpu ect as there's no such thing in the control panel.
well there's a simple solution for it.Download and install htop , how ? follow the guidelines below.
To install htop to Redhat or CentOS (5.X) Linux easily via the yum package manager, the rpmforge package repository must be installed. To install, retrieve, and install the following RPM for your architecture (32bit or 64bit).
rpm -Uhv rpmforge-release*.rf.i386.rpm
rpm -Uhv rpmforge-release*.rf.x86_64.rpm
Now that the rpmforge repository is installed, you can install the htop package easily via yum.

You're done, to use it now simple type : htop , you'll be able to view the usage and monitor it along with terminating some running applications you're not using.
Or simply use the default : top
