MySQL Enterprise Monitor is available as part of the MySQL Enterprise subscription, learn more at http://www.mysql.com/products/.
The Status Summary:
The Status Summary is displayed on every page, updates dynamically, and shows current status counters for:
Hosts monitored: Local Agents are installed and collecting operating system related data.
MySQL Instances monitored: Agent connections are successfully configured, and Instances are actively monitored
MySQL Instances with invalid connection configurations: Agent configurations exist but are not yet valid; correct or delete these connections on the MySQL Instances Dashboard.
Unmonitored MySQL Instances: These running mysqld processes were detected by one or more Agents; configure connections to begin monitoring or ignore them on the MySQL Instances Dashboard.
Emergency Events: These high priority problems require your immediate attention.
The Status Summary is global, so it does not take into account current filters such as Groups or selections in the Asset Selector. Therefore, a particular page may display results that differ from the global Status Summary overview.
The Status Summary counters are live links that link each value to its appropriate MySQL Enterprise Monitor User Interface page. Click the links to reveal additional details and tools to help resolve reported issues.
