Class MonitoringStore

java.lang.Object

org.opentripplanner.util.monitoring.MonitoringStore

public class MonitoringStore
extends Object

This supports the monitoring of various system properties, such as free memory. Think of it like a logger, except that it can be read from inside the system and it supports tracking max values as well as a list of notes. The use pattern, when monitoring is expensive, is to check isMonitoring before computing anything. TODO: allow registering special case monitoring for complex cases like long queries.
