This chapter describes the process of installing the MySQL Enterprise Monitor on all operating systems.
A working installation requires the following:
One MySQL Enterprise Service Manager. It stores its data in a database repository. You can use an existing MySQL instance for the repository, or set up a separate instance as part of the MySQL Enterprise Service Manager installation. See Chapter 4, Service Manager Installation.
Optionally (but recommended), one or more MySQL Enterprise Monitor Agents, one for each host to monitor. See Chapter 5, Monitor Agent Installation. Install the MySQL Enterprise Service Manager first, because the Agent installation asks for credentials and network settings that you choose as you install the MySQL Enterprise Service Manager.
To minimize network overhead, you usually install the Agent on the same machine that hosts the monitored MySQL server, but you can install it on any machine that has network access to both the monitored MySQL server and the MySQL Enterprise Monitor User Interface. In other words, an agent may monitor either locally, remotely, or both.
While it is possible to use a single agent to monitor multiple hosts, it is not recommended for performance reasons.
The Agent monitors the MySQL server, and transmits health and usage data back to the Service Manager. The Advisors interpret the results, which are displayed in the browser-based MySQL Enterprise Monitor User Interface.
After installing and starting the Service Manager and Agents, configure the settings in the MySQL Enterprise Monitor User Interface, as explained in Section 4.5, “MySQL Enterprise Service Manager Configuration Settings”.
