Please indicate the scope of monitoring this installation will initially encompass so we can configure memory usage accordingly. NOTE: This setting may have a big impact on overall performance. The manual contains instructions for updating the configuration later, if needed. This installation will monitor a:
System Size
[1] Small system: 1 to 5 MySQL Servers monitored from a laptop computer or low-end server with no more than 4 GB of RAM
[2] Medium system: Up to 100 MySQL Servers monitored from a medium-size but shared server with 4 GB to 8 GB of RAM
[3] Large system: More than 100 MySQL Servers monitored from a high-end server dedicated to MEM with more than 8 GB RAM

[2] I wish to use an existing MySQL database *
Please choose an option [1] :
* We will validate the version of your existing MySQL database server during the
installation. See documentation for minimum version requirements.
* Important: If your existing MySQL database server already has another MySQL
Enterprise Monitor repository in it that you want to keep active, be sure to
specify a unique name in the "MySQL Database Name" field on the next screen.

WARNING: To improve security, all communication with the Service Manager uses
SSL. Because only a basic self-signed security certificate is included when the
Service Manager is installed, it is likely that your browser will display a
warning about an untrusted connection. Please either install your own
certificate or add a security exception for the Service Manager URL to your
browser. See the documentation for more information.

You can configure the Agent to monitor this host (file systems, CPU, RAM, etc.)
and then use the Monitor UI to furnish connection parameters for all current and
future running MySQL Instances. This can be automated or done manually for each
MySQL Instance discovered by the Agent. (Note: scanning for running MySQL
processes is not available on Windows, but you can manually add new connections
and parameters from the Monitor UI as well.)

[1] Host only: Configure the Agent to monitor this host and then use the Monitor UI to furnish connection parameters for current and future running MySQL Instances.
[2] Host and database: Configure the Agent to monitor this host and furnish connection parameters for a specific MySQL Instance now. This process may be scripted. Once installed, this Agent will also continuously look for new MySQL Instances to monitor as described above.
