This chapter describes the architecture of the various Proxy, Aggregator and Connector installations and the installation process for the Proxy and Aggregator components.
The MySQL Enterprise Monitor Aggregator requires a framework, or chassis, to handle the communications between the client application and the MySQL instance. The following frameworks are available:
MySQL Enterprise Monitor Proxy: the Proxy functions as the communications chassis for the Aggregator and is responsible for intercepting the communications between the client application and the MySQL instance. This enables the Aggregator to collect the raw query data sent from the client application to the MySQL instance. The MySQL Enterprise Monitor Proxy and Aggregator installer can install and configure both Proxy and Aggregator, or a standalone Aggregator if one of the MySQL connectors is used as the communications chassis. The client application must be configured to communicate with the MySQL Enterprise Monitor Proxy.
MySQL Connectors: the MySQL Connectors enable communication between the client application and the MySQL instance. If you intend to use a MySQL Connector as the communications framework for the MySQL Enterprise Monitor Aggregator, you must configure the Connector to communicate with the Aggregator. If you use a Connector with the Aggregator, you do not need to install the MySQL Enterprise Monitor Proxy.
