Metrics summary graph in JBoss ON is misleading

Solution Unverified - Updated -

Issue

  • Metrics summary graph is misleading
  • Metric summary graph line will drop to 0 in between two collection points although metric value is constant and not equal to 0
  • Metric summary graph shows spikes with the correct value at the collection point but drops to 0 in between two collection points

Environment

  • Red Hat JBoss Operations Network (ON) 3.2, 3.3
  • Resource measurement that is collected periodically and never has a value of 0
  • Reviewing the metric summary chart for a time period that would include less then 60 collections of the metric -- For example, if Max Pool Size is collected every 20 minutes and you click on it in the metrics monitoring page to view its summary chart for the last hour
