Database Environment Tiles

The Database Environment tiles display a high-level overview of your database environment. There is a tile for each type of database currently monitored by Foglight: All Instances, SQL Server, Oracle, Sybase, and DB2. Each tile shows how many of the corresponding object instances there are in your database infrastructure, and the count of objects of that type in each of the alarm states (Normal, Warning, Critical, Fatal).

Clicking the object type icon, the object type name, or the object count, shows summary information for that object type in the Databases Instances View. Clicking an alarm state (for example, Warning) on a tile displays summary information in the Databases Instances View for the objects in the selected state.
