Subject Re: Graphs and HeatMaps are Not Visible on Ambari Web-UI
Date Thu, 12 Jun 2014 13:41:25 GMT
 
Hi,

I have disabled the SELinux.

[pts/2][19:06:59:root@INBBRDSSVM50 ] /u01/HomeDir/NGA>getenforce
Disabled

But stil I am not able to view all graphs on Ambari Web_UI.
Only Hbase Graphs are visible but HDFS and YARN realated graphs are Not visible.
Same case with Heatmaps.

I tried by restting whole setup of ambari.
Even tried ambari-server and aganet, hdp-gmond and hdp-gmetad restart, but Graphs are not
displayed.

I am able to view all graphs on ganglia web UI but those are not visible on Ambari Web UI

:(

If it's permissive, it's not in your way. It will show what it would have stop but it should
not stop anything.

Hi

Getenforce status is Permissive only.

[pts/0][14:05:43:root@INBBRDSSVM50 ] /var/nagios>getenforce
Permissive

but its not working. Do I have to disable it?
 Is there any other option?

You can run 
 getenforce, it should give you the status (enforcing, disabled or permissive) 
 If you're in enforcing, you can switch it to permissive by running 
 setenforce 0
 Fyi, I don't believe that Ambari can runÿ with selinux enabled. It might be better to switch
it off once for all by editing /etc/selinux/config

You can run the following to temporarily disable SELinux until the next server reboot.
echo 0 >/selinux/enforce

Hi Sid,

Thanks for reply.

All rrd files related to Namenode, HBase, Mapreduceare are being written to /var/lib/ganglia/rrds/

   I cant disable SELinux. Because disabling it requires rebooting of system.

Is there any other way which can handle this issue.

Few graphs that of hbase are visible but that of HDFS and YARN Mapreduce are Not Displyed

Hi Meghavi,

Are you able to obtain metrics data by turning off SELinux temporarily on Ganglia host ?
   
Also, are rrd files being written to /var/lib/ganglia/rrds/ ?
