    hi, I have just installed the lates HDP 2.0 cluster, all looks good. but some system status is not displayed on ambari home page.
    including memory usage, network usage,CPU usage and Cluster Load. I guess nagios is not working well with ambari server, how do I troubleshoot this?

    A few things:

    1) This is on the Dashboard page? On the Services or any of the Host pages, do you see the graphs?
    2) Those graphs are generated based on the metrics data collected in Ganglia. So it’s not related to Nagios.
    3) What is the time difference between the hosts in your cluster? All running ntp so time is in-sync? How about difference between your local machine (where you are accessing via browser) and the Ambari server host?

    hi Jeff
    thanks for your reply and sorry I didn’t answer your questions in time.
    1, yes I am looking at the Dashboard page, there are graph labeled like “memory usage” on dashboard but nothing is displayed in the graph, when I open ganglia web page directly, I do see some graph showing CPU and memory usage. but why they are not displayed on Dashborad?
    2, all the cluster machines’ time are synced with, the same for my Windows client which is used to browse the web page. so time should be synced well.

    thank you.

    Any solution about this? My HDP 2.0.6 cluster has the same issue.

    Thank you!

    Hi Michael/Jason,

    Are you able to see graphs if you navigate to Ganglia page directly? Usually such issues happen if time is not synced in the cluster.
