The central processing unit (CPU) counters include information about the percentage of
time that is spent by the central processing unit in various states, the number of interrupts and
context switches, and memory information as available. The percentage of the central processing unit
time totals 100% across the following categories. Although these values are represented in the
Dashboard as event counters, they are more properly viewed as meters because they represent absolute
values 0 - 100%. These counters are common to all components.
Central processing unit utilization counters

Java™ specific central processing unit counters
| Property |
Description |
| jvm_free_memory |
The amount of free memory, in megabytes, in the Java virtual machine. |
| jvm_total_memory |
The current total memory that is used by the Java virtual machine. The total is less than the value shown in the environmental information for jvm_max_memory. |
