Subject [jira] [Commented] (FLINK-1792) Improve TM Monitoring: CPU utilization, hide graphs by default and show summary only

    Hey Robert,
           The required changes have been made and are working fine for Java 7 onwards. Using
this method, it is not possible to fetch CPU load in Java 6 since there is no implementation
of the getProcessCpuLoad method available for OperatingSystemMXBean: 

           There is a compilation error due to the unavailable method in jdk 6 and hence the
Travis failures. What do you suggest should be the next step?

to the current monitoring required

(cpu load, heap utilization) and add a button to enable the detailed graph.
