Use

In the workload monitor, you can display the workload in different Analysis Views, which highlight the workload from a particular perspective. One of these views shows how the available resources are made use of at specific times when the VM Container is operating. With this information, you can answer questions such as:

  • How often has the VM Container been called up?

  • How often has the garbage collector been called for the various memory areas (old generation, young generation, shared objects)? (see Memory Management in the VM Container)

  • How much time has the system spent in the various garbage collections?

  • How many JIT compilations have there been?

Procedure
