Subject [jira] [Created] (AMBARI-6575) Linked Ganglia charts from Host Details page don't show any graphs (except on NameNode host)
Date Wed, 23 Jul 2014 12:45:39 GMT
Antonenko Alexander created AMBARI-6575:
-------------------------------------------

             Summary: Linked Ganglia charts from Host Details page don't show any graphs (except
on NameNode host)
                 Key: AMBARI-6575
                 URL: https://issues.apache.org/jira/browse/AMBARI-6575
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.7.0
            Reporter: Antonenko Alexander
            Assignee: Antonenko Alexander
             Fix For: 1.7.0


The UI links to Ganglia Web to display the graphs for a specific host as 
http://<ganglia-host>/ganglia/mobile_helper.php?show_host_metrics=1&h=<target-fqdn>&c=HDPNameNode&r=hour&cs=&ce=

Note that c=HDPNameNode is static.
I believe this worked before as the NameNode gmond was repeated on all the hosts (we should
not have and this has been fixed but now it's causing this issue).

For this ticket, let's change the call the UI makes from "HDPNameNode" to "HDPSlaves" and
verify that host-level Ganglia links work for all hosts on a multi-node cluster (including
hosts with clients only).
