Description

The MonitorMemory reporting task is intended to report when heap is becoming exhausted by comparing the amount of heap used immediately after the most recent garbage collection to the configured threshold. It appears that this was broken in NIFI-1690, in which the code was changed to use MemoryPoolMXBean.getUsage() instead of MemoryPoolMXBean.getCollectionUsage()
