Class DatabaseConnectionPoolMetricSet

java.lang.Object

org.kuali.rice.web.health.DatabaseConnectionPoolMetricSet

All Implemented Interfaces:

com.codahale.metrics.Metric, com.codahale.metrics.MetricSet

public class DatabaseConnectionPoolMetricSet
extends Object
implements com.codahale.metrics.MetricSet

A set of metrics that indicate min, max, and active number of connections in the pool as well as the percentage of connection pool usage. Supports XAPool, Bitronix, and DBCP datasources. Will attempt to unwrap the underlying DataSource implementation if the given DataSource is a wrapper for one of these types. If the given DataSource is of an unknown type, this class will silently fail and invocations of getMetrics() will return an empty map.
