How do find out which table is consuming resources under MySQL Database server from UNIX shell prompt?

One can use mytop command a console-based (non-gui) tool for monitoring the threads and overall performance of a MySQL.

Install mytop

First install required perl modules:

cpan -i Term::ReadKey
cpan -i Term::ANSIColor
cpan -i Time::HiRes

Next, install mytop, enter:

wget http://jeremy.zawodny.com/mysql/mytop/mytop-1.6.tar.gz
tar -zxvf mytop-1.6.tar.gz
cd mytop-1.6
perl Makefile.PL
make
make test
make install

To view information about database called foo, enter:

$ mytop -u dba -p 'password' -h 10.2.4.5 -d foo

Where,

-u : Database username.
-p : Database password.
-h : Database server IP address.
-d : Database name.
