Description Larry O'Leary 2011-11-08 15:18:58 EST
Currently, when MeasurementCollectorRunner has requests which have a collection scheduled earlier then the current time minus 30 seconds, a debug log message is produced that looks like: "Measurement collection is falling behind... Missed requested time by [" + (System.currentTimeMillis() - requests.iterator().next().getNextCollection()) + "ms]"

(See http://git.fedorahosted.org/git?p=rhq/rhq.git;a=blob;f=modules/core/plugin-container/src/main/java/org/rhq/core/pc/measurement/MeasurementCollectorRunner.java;h=269f6266724f2ea17a771e0fb702d7abba5a0ae8;hb=release-3.0.1#l71)

Such a message seems like something that is potentially harmful or should be addressed and DEBUG level does not seem appropriate for this message. Can this be changed to WARN?

Falling behind is an indication of overload (may be the agent, but also the target server), so this is definitively more important than just debug level.
