2.2 The Monitor Tab

2.2.1 The Server Graphs and Critical Events
2.2.2 The Heat Chart

The Monitoring tab, which is shown first when you log in to MySQL Enterprise Monitor User Interface, provides a quick overview of your current monitoring information, and provides an instant health check for all of the MySQL servers across the enterprise.

From this page, you can:

Graphs are shown in the center of the page beneath the tabs. If applicable, you also see a list of critical events.

On the right is the color-coded Heat Chart, showing the advisors that are installed by default. The Heat Chart shows the most important advisors, allowing a quick overview of the state of your servers. You can open the Heat Chart in its own window by clicking the Standalone Heat Chart link. If applicable, you also see a list of critical events.

The Show/Hide Legend link toggles display of the explanations of the icons used in the Heat Chart.


Find colorblind-accessible icons in the alternate directory. On Linux, this directory is immediately below the /monitor/apache-tomcat/webapps/ROOT/web/resources/images/ directory. These images are stored in the same directory on Windows. To use them, back up the originals and then copy and paste the alternate set into the images directory.

When a specific server is selected in the Server Tree, the Meta Info area beneath the legend shows details about this server. The information shown in this area is the host name, the MySQL version number, the number of scheduled rules, the operating system, and the CPU.

The Meta Info section also shows how long the agent has been running, when it last contacted the MySQL server it is monitoring, and the last time the agent contacted the dashboard. When you mouse over the date shown beside Up Since, a pop-up box displays the elapsed time since the server instance was last started. You can also mouse over the Last MySQL Contact and the Last Agent Contact dates.


In the case of remote monitoring, the agent runs on a different machine than the MySQL server that it is monitoring. The Hostname, MySQL, and Rules information applies to the system being monitored. The OS and CPU information applies to the machine on which the agent is running.
