Every minute, the system collects memory information from the different Java processes defining the Platform and the Execution Context. This information shows how much memory is used and how much memory that is available for the running process.
Used Memory - Shows the amount of memory currently allocated by the running process. As Java is a language utilizing garbage collection, this number may very well get close to the maximum memory limit without being a problem for the running process. However, if the amount of used memory is close to the maximum limit for a long time, the process needs more memory. This value is displayed in bytes. See the -Xmx and -Xms properties defined in the XML file defining the process.
Maximum Memory - Shows the amount of memory that the process can use. This value is displayed in bytes.
Process CPU Time - Shows the percentage of CPU time that has been used.
Open File Descriptors - This is a Unix measurement that enables you to create a statistical diagram over the number of open files during the last minute, hour, or day.
Garbage Collection Count - Shows the number of times the garbage collector has run since the last time statistics was collected.
Garbage Collection Time - Shows the amount of time the garbage collector has run since the last time statistics was collected. This value is displayed in milliseconds.
Thread Count - Shows the number of allocated threads.
