you use MySQL, the MySQL Control Center is ahandy tool to add to your collection. Check it out! Watching Your MySQL Trafficwith mtopMySQLCC is a great monitoring tool if you re runningin a graphical environment, but if you keep yourservers and data in a non-GUI environment, use mtop. mtopis a handy command line tool that lets you watchyour database traffic and transactions. You can alsouse mtopto help find and debug slow queries. Graphical tools are available everywhere nowa- days, but you can save money and improveperformance by keeping your MySQL serversin a nongraphical environment. Gathering all the packages that mtop needsYou need a number of prerequisite packages to runmtop. Obviously, you need to be running MySQL. Youalso need the mysql-develRPM package that goeswith the MySQL version you re running. Both areincluded on the Fedora and SuSE distributions andcan be added with either the Package Manager or asRPM packages from a distribution disc. If you re aMandrake user, you ll have to find the mysql-develpackage on the Web. You need to download and install a few Perl modulesbefore you can install mtop. The easiest way to installPerl modules is to use the CPAN (Comprehensive PerlArchive Network) interface. CPAN retrieves Perl mod- ulesand installs them on your system automatically. You need to have Internet access for themachine you re using CPAN with. To install Perl modules with CPAN, follow these steps: 1.Open a terminal window, give yourself super- user privileges with the sucommand, and enterthe following command: # perl -MCPAN -e install DBI 2.When you re asked if you re ready for manualconfiguration, type noand press Enter. CPAN continues to work, retrieving the Perl DBImodules. Depending on your system and connec- tion speed, this could take a few minutes. 3.Enter the following command: # perl -MCPAN -e install DBD::mysql If you have trouble installing the DBD::mysqlmodule, be sure you ve installed the mysql- develRPM package. DBD::mysqlwon tinstall without it. 4.Enter the following command: $ perl -MCPAN -e install Getopt::Long 5.Enter this command: $ perl -MCPAN -e install Net::Domain The last Perl module that you need is Curses. At thetime we re writing this, the Curses module availablefrom CPAN fails to install on Fedora (and possiblyother distributions as well). To install Curses, followthese steps: 1.Open a Web browser and surf tobastille-linux.org/perl-rpm-chart.html2.Click the most recent link to download perl- Curses (Text/Console). Currently, that version is for Red Hat 9; it worksfine with Fedora. 3.Save the RPM package to your home directory. 4.Open a terminal window and give yourselfsuperuser privileges with the sucommand. 5.Move to your home directory. 6.Install the perl-CursesRPM package with thefollowing command: # rpm -Uhv perl-Curses-1.06-219.i586.rpmNow that the program dependencies are in place, you re ready to download and install mtop, asdescribed in the next section.
