We can monitor mysql queries and database using an utility called MonYog. MONyog is a monitoring and advisory tool for MySQL Community as well as Enterprise versions.MONyog is agent-less, and does not require anything to be installed on the MySQL servers. MONyog helps monitor enterprise database environments.
MONyog MySQL Monitor and Advisor MySQL DBAs manage more MySQL servers,and tune their MySQL servers.
To install monyog get the rpm / tar.gz package
# rpm -ivh monyog.version.rpm
# service monyog start / stop
