Overview

SQL Diagnostic Manager for MySQL is an IDERA product that allows you to monitor MySQL and MariaDB databases. The product is a low-overhead, low-maintenance tool that is easy to install and easy to use. The product is robust and flexible and helps you pinpoint the servers, database, tables, and other activity in your environment that needs your attention. Some customers monitor up to 1,200 instances.

Architecture

SQL Diagnostic Manager for MySQL is a Linux and Microsoft Windows application that runs on a server. The product is entirely self-contained. As such, the product does not require any client agents, web servers, and any other software installed. The product connects to your MySQL instances across the network and uses low-overhead and well-documented commands to gather information about the sessions, activity, and SQL statements that MySQL is executing, as well as server configuration and various logs.

The product stores the gathered information in an internal SQLite database. SQLite is a low-maintenance database that grows to roughly 3 GB to 5 GB of size per instance monitored. The size of SQLite depends on the amount of activity on the monitored server. The documentation details the schema. Moreover, both web-based and command-line utilities are available for SQLite when you choose to access the data directly. Most users, however, view pages, graphs, and other information through the web-based component of the product. Users connect to the host via any standard web browser.
