How to determine the min and max value of heap size , and actual heap size consumption

I ran this command on ubuntu in which ColdFusion and OpenJDK to determine the min and max heap size , and how much heap size ColdFusion is using

jcmd 1982 GC.heap_info

but I am not able to understand the output (I need min max , actual utilization of heapsize so which value is actual value from this output)
