All this information can be used to optimize the MySQL server performance. Run the following command to install and enable the EPEL repository on your server:.

Next, let us protect the base packages from EPEL using the yum plugin protectbase. The purpose of the protectbase plugin is to protect certain yum repositories from updates from other repositories.

Packages in the protected repositories will not be updated or overridden by packages in non-protected repositories even if the non-protected repository has a later version.

Before using mytop, create a customized configuration file for mytop named. Run the command:. This configuration file will be used when you run mytop directly as root and when you run it with the sudo command in front of it as a non-root sudo user.

You can make changes to this configuration file depending on your needs. For example, the delay option specifies the amount of time in seconds between display refreshes.

The idle parameter specifies whether to allow idle sleeping threads to appear in the list in mytop display screen.

The default is to show idle threads. If idle threads are omitted, the default sorting order is reversed so that the longest running queries appear at the top of the list.

You can refer the manual pages of mytop for information on all the parameters in the configuration file — it contains a description of each parameter.

To access the manual page, use the command:. Mytop requires credentials to access the database, which can be provided via a prompt, on the command line, or stored in the configuration file.

For better security, we will use the --prompt option to mytop, which asks for the password each time. Let us connect to mytop using:.

You can also use several command line arguments with the mytop command. Please refer the manual page for the complete list.

For example, if you want to use a different mysql user such as sammy to connect to mytop, run the command:. In this section, we will see how to interpret mytop display and the different features offered by the tool.

Once we connect to mytop using mytop --prompt we will be taken to the thread view. It will show something similar to:. The above display screen is broken into two parts.

The header contains summary information about your MySQL server. The first line identifies the hostname of the server and the version of MySQL it is running.

The second line displays the total number of queries the server has processed in our case , the average number of queries per second, the number of slow queries, and the percentage of Select, Insert, Update, and Delete queries.

The third line shows real-time values since last mytop refresh. The normal refresh delay time for mytop is 5 seconds, so if queries were run in the last 5 seconds since the refresh, then the qps now number would be The first field is the number of queries per second qps now: 2.

The second value is the number of slow queries per second. The last field in the third line shows the query percentages, like in the previous line, but since last mytop refresh.

The fourth line displays key buffer efficiency how often keys are read from the buffer rather than disk and the number of bytes that MySQL has sent and received, both overall and in the last mytop cycle.

Key Efficiency: 2. The second part of the display lists current MySQL threads, sorted according to their idle time least idle first. You can reverse the sort order by pressing O if needed.

The thread id, username, host from which the user is connecting, database to which the user is connected, number of seconds of idle time, the command the thread is executing or the state of the thread , and first part of the query info are all displayed here.

If the thread is in a Query state i. Cmd displays Query then the next column Query or State will show the first part of the query that is being run.

If the command state is Sleep or Idle then the Query or State column will usually be blank. In our example output above, thread with id 2 is actually mytop running the show processlist query to collect information.

The thread with id 16 is sleeping not processing a query, but still connected. Now that we have understood the basic display of mytop, we will see how to use it to collect more information on the MySQL threads and queries.

Let us take a look at the following mytop display:. In the mytop thread view default view shown above, the queries are truncated.

To view the entire query, you can press F , and it will ask:. Enter the thread id for the query you want to see. For example, enter In this MySQL monitoring tutorial, we will show you how to install, configure and use mytop on various Linux distributions.

To install Mytop , run the appropriate command below for your Linux distribution to install it. This will connect to the test database by default.

This file can be viewed later on by an unauthorized person who might land on the username and password.
