Mytop is a top-like realtime command line based monitoring system for MySQL. It is written by Jeremy Zawodny, and is available for free download. It runs on most UNIX-based systems, and most definitely on Linux machines. This kind of real-time monitoring can be very useful when administering a MySQL server.
You need a working MySQL server and a few Perl modules such as DBI, DBD::mysql, Term::ReadKey, and Getopt::Long to be able to use mytop. You can download the source code version of mytop from the project’s website, or you can get a pre-built binary package for your distribution. I know that there are packages for Fedora/Redhat and for Ubuntu systems. You should be able to find them pretty easily on the web. Once you get the binary version of mytop install it.

wget http://jeremy.zawodny.com/mysql/mytop/mytop-1.6.tar.gz
tar -zxf mytop-1.6.tar.gz
cd mytop*
perl Makefile.PL
make test
make
make install
Once you have installed mytop you can check if it is working using the following command:
# mytop -h dbserver -u dbuser -p dbpassword

Replace dbserver, dbuser, and dbpassword with the correct credentials of your MySQL server. This ought to get you off the blocks with mytop. You can read up this documentation if you want to see a list of options supported by mytop
