    Hey Robert, please correct me if I am wrong. According to this doc,
    https://docs.oracle.com/javase/7/docs/jre/api/management/extension/com/sun/management/OperatingSystemMXBean.html
    OperatingSystemMXBean of the sun package is available for Java 6 too. Only the method
getProcessCpuTime is unavailable. Hence I believe the logging and exception will not occur
for each heartbeat.

> As per https://github.com/apache/flink/pull/421 from FLINK-1501, there are some enhancements
to the current monitoring required
> - Get the CPU utilization in % from each TaskManager process
> - Remove the metrics graph from the overview and only show the current stats as numbers
(cpu load, heap utilization) and add a button to enable the detailed graph.
