Check Your Mysql Server Performance with MySQLTuner -- Debian Admin

by 1 other
MySQLTuner is a script written in Perl that will assist you with your MySQL configuration and make recommendations for increased performance and stability. Within seconds, it will display statistics about your MySQL installation and the areas where it can be improved. It’s key to remember that MySQLTuner is a script which can assist you with your server, but it is not the solution to a badly performing MySQL server. The best performance gains come from a thorough review of the queries sent to the server, and an evaluation of the MySQL server itself. A qualified developer in your application’s programming or scripting language should be able to work with a MySQL database administrator to find improvements for your server. Once the server and application are optimized well, you may need to consider hardware upgrades to the physical server itself. This is a really useful tool for helping to optimize MySQL performance.Understanding the various my.cnf variables and how they affect performance can seem really complicated but this tool takes some of the pain away and makes it easier to understand the effects of each variable.It is especially useful to be able to see the global memory usage, memory usage per thread and the maximum possible memory usage - that is really valuable information that is otherwise complex to calculate.

NagiosExchange: Categories: Utilities

This Script is coded to install the latest Nagios-Version (CVS) and the Nagios Plugins 1.4.11 automatically! It's meant to be a help for testing, searching bugs or simply to install Nagios and the Plugins without harking back to the Ubuntu-Package. First the dependencies will be fixed, missing packages will be installed via apt. The next step is adding the groups and user which are necessary for Nagios. After that the latest Nagios Tarball will be downloaded and installed. If errors occur while the installation process you have to kill the script (Ctrl c) and fix it manually. After that you can run the script again. Then the standard-user (named "nagios") for the Frontend will be created and you will be asked to set a password for it. Done, Nagios is installed. Now the plugins are going to be installed. Same procedure, downloading, configuring, installing. I tried to meet all requirements, so that every plugin will be compiled, but i did'nt check it. Have fun.
