Switches the page to the Process display option. -
Switch to APPLICATION mode
Switches the page to the Application display option. -
Switch to CURRENT mode
Switches the page to the Current display option. -
Switch to VIA mode
Switches the page to the Via display option. -
Application Methods
Displays the JVM Methods subpage showing application methods for the selected process. -
Via Methods
Displays the JVM Methods subpage showing via methods (called by the application) for the selected process. -
Current Methods
Displays the JVM Methods subpage showing current (last-called) class methods for the selected process. -
Threads
Displays the JVM Thread TCBs subpage showing threads for the selected process. -
Method Details
Displays the JVM Method Details subpage showing line numbers in the selected method where activity was measured. -
Processes

JVM Columns
-
Process ID
The identification numbers or the processes monitored using a Java Virtual Machine. -
JVM Release
The release level of the Java Virtual Machine. (obtained from java.vm.version) -
Pct %
The percentage of all JVM activity measured where CA MAT detected program code to be executing.
This value is calculated based on the total of JVM activity, not the total number of CA MAT samples. -
JVM Information
The Java Virtual Machine System Properties (obtained from java.vm.info)
JVM Thread TCBs
-
Thread TCB
The Thread identification value (or TCB address). -
UNIX Thread ID
The UNIX Thread associated with the Thread TCB. -
Pct %
The percentage of all JVM activity measured where CA MAT detected program code to be executing.
This value is calculated based on the total of JVM activity, not the total number of CA MAT samples.
