Hello Bob- Non Heap memory used would be made up of Code Cache Compressed Class Space Metaspace Non-Heap Memory Usage is the amount of memory allocated with objects for those above spaces. JVM - Max Memory and Heap Memory Usage - Max are normally the same value. In CFadmin that is related to Server Settings > Java and JVM > Maximum JVM Heap Size (in MB) tho it can be different by a small amount according to Garbage Collector in use, what value is present for Minimum JVM Heap Size (in MB), how long CF has been up and if any full garbage collections have run. Non-Heap Memory Usage - Max would be the memory taken for list above but not necessarily occupied with objects, free space ready to accept objects. Note Metaspace for Java 8, Perm Gen for end of life Java 7. Hope that helps, Carl.
