Overview of Collections

Foglight for Oracle collects raw data for a set of collection types. This data is used by the Rules to trigger alarms and is used to populate dashboards. The collections data tables are not viewable from Foglight for Oracle, but the data is implemented in the various drilldowns of Foglight for Oracle.

The collection data tables are not viewable from Foglight for Oracle.


	NOTE: Several collections contain metrics whose name ends with Rate (for example: DBO Wait Buffer Busy Rate). Such metrics, which are not documented in this guide, are used for plotting the original metric (usually called by the same name without the “Rate” suffix) on a graph for the selected time range.

Alert Log

The Alert Log collection retrieves the content of Oracle alert log.
