The default opennms.properties file fails to mention that the following properties should be set any time data collection and/or polling intervals are altered on a system persisting data to Newts:

The values above are appropriate for a system collecting or polling any service every 30 seconds. The value of heartbeat should nominally be 1.5 times the value of minimum_step. The value of minimum_step should be set to the shortest collection interval configured for any collectable or pollable service on the system. These rules also apply for metrics collected via streaming telemetry.
