> Currently, the task counters report VSS and RSS usage of the task. The task
> counter should also report the total heap usage of the task also. The task
> might be configured with a max heap size of M but the task's total heap usage
> might only be H, where H < M. In such a case, knowing only M doesn't provide
> a complete picture of the task's memory usage.
