13.1.2 Asset Selector


MySQL Enterprise Monitor is available as part of the MySQL Enterprise subscription, learn more at http://www.mysql.com/products/.

MySQL Enterprise Monitor 3.0 features a new Asset Selector on the left side of many UI pages that controls content in the main-body of the page. On the Events page, for example, selecting a Host, Group, or MySQL Instance will display only those Events relevant for the selected Asset. Reports & Graphs pages also feature a full-blown Asset Selector, while other UI pages show or hide various Asset types depending on the content of the page.

The Asset Selector content is automatically populated as monitoring connections are made and maintained and state information is gathered. The Groups shown in the Asset Selector are the ones you create and manage (on the MySQL Instances dashboard or during Agent installation), and those that are discovered automatically from monitoring replication topologies.


Use the Magnifying glass icon at the top of the Asset Selector panel to open up a control panel:

The Show All Assets checkbox. Toggle showing only Groups and MySQL Instances ("streamlined" mode) or showing all known Assets. These include:

In "stream-lined mode", MySQL Instances are directly contained in Groups. In "All" mode, Groups contain Hosts, which then contain the MySQL Instances running on those Hosts; the same Group membership is represented but with a bit more detail about the operational relationship. Agents are also shown and listed as subordinate to the Hosts that they are running on.


The Query Analyzer page does not allow the selection of the "All" mode, as Query Analyzer only applies to Groups of MySQL Instances.

There is also a control to horizontally collapse the entire Asset Selector against the left-hand side of the page and allow the main-body content to take more screen width.

Asset Naming

Most Assets names are automatically derived from the conventional name and other identifying details of the Asset. For example, MySQL Instances are displayed as the "[hostname]:[port]" of the instance unless you have manually edited the Display Name on the MySQL Instances page.

Network interfaces display as: "[network-interface name] ([network address])", while File Systems are shown as: "[mount-point name] ([filesystem type])".

Agents are listed as "Agent ([UUID-fragment])", where "UUID-fragment" is the first and last 3 characters of the Agent's internal UUID (the remaining 26 characters are omitted); these 6 characters should be sufficiently unique to help you identify the right Agent when the UI presents you with a selection list.

Finally, the Service Manager has a built-in Agent that will be displayed as "MEM Built-in Agent".

Emergency Event Badges

The Asset Selector will display a numeric "badge" next to any Asset that has open Emergency Events. Click on the badge to view the Emergency Events.

MySQL Instance Notes

If you annotate a MySQL Instance with a Note on the MySQL Instances page, the Asset Selector will display a Note Icon to the right when you hover over the Instance. View the Note in a tooltip by then hovering over the Note Icon.
