A free tool to analyze AIX and Linux performance

Image
One of the tools I use to monitor performance on IBM AIX 5.3 and Linux is NMON. Using nmon, you can monitor CPU, memory, network, disk, filesystems, NFS and Top Processes. Install Nmon CentOS users need to install nmon from rpmforge/repoforge repository. It is not present in Epel.
