                Installing nmon on Amazon Linux AMI
              
          
    Installing nmon on Amazon Linux AMI

nmon is an excellent performance monitor for Linux systems.
Since Amazon Linux AMI is compatible with RHEL5, I've downloaded a binary RPM from:
http://pkgs.repoforge.org/nmon/
$ wget http://pkgs.repoforge.org/nmon/nmon-14g-1.el5.rf.i386.rpm
