AWS Performance Insights
API Reference (API Version 2018-02-27)


An object describing a Performance Insights metric and one or more dimensions for that metric.



In the following list, the required parameters are described first.


The name of a Performance Insights metric to be measured.

Valid values for Metric are:

  • db.load.avg - a scaled representation of the number of active sessions for the database engine.

  • db.sampledload.avg - the raw number of active sessions for the database engine.

If you have less active sessions than an internal Performance Insights threshold, db.load.avg and db.sampledload.avg are the same value. If you have more active sessions than the internal threshold, Performance Insights samples the active sessions, with db.load.avg showing the scaled values, db.sampledload.avg showing the raw values, and db.sampledload.avg less than db.load.avg. For most use-cases, it's sufficient to query db.load.avg only.

Type: String

The valid dimensions for the metric.
