How to get a detailed MySQL status report

If you use or administer a MySQL server you probably know what a pain it can sometimes to get a proper status report that you can easily decipher and understand. mysqlreport is an script written in Perl that makes the job a lot easier for you. The script takes the output of the command SHOW STATUS’ in MySQL and displays it in a neatly formatted manner which makes it a lot easier on the eyes, and as a result easier to figure out what’s going on.

Let’s take a closer look at it by installing it. I’ll be using a Linux machine for this exercise. I’m assuming that you have MySQL up and running and that you have Perl installed. Get the latest release of mysqlreport from the Download section on the project’s website. Copy it to some place in your computer’s PATH, such as /usr/bin/. Make the script executable with the following command:

# chmod 755 /usr/bin/mysqlreport

Installation is now complete. Let’s proceed to usage. We’ll take a look at some basic usage here. For a detailed list of what you can do with mysqlreport run the following command:

# mysqlreport --help

To get a report of your MySQL server run the following command, replacing the hostname, username and password with the correction credentials for your server:


# mysqlreport --host dbserver --user dbuser --password
Password for database user dbuser:
