Hi Meghavi,

Since you do = have rrd file created and graphs appearing in the Ganglia UI, I do not this= the problem is in the udp channel between the gmond daemons.

Can you look at the ambari server log, /var/log/ambari-server/ambari-server= .log?
You are likely to see exceptions from the GangliaPropertyPro= vider. Could you provide the exception message?

-Sid

-rwxr-xr-x. 1 root root 5706 Jun=C2=A0 9 18:42 /var/www/cgi-bi= n/rrd.py

Make sure this file exists with right permi= ssions.

Lastly, make sure you h= ave increased ulimits, default is 1024 which could be very small, based on = you cluster size.

Hi Meghavi,

You should be able to debug this by editing, /etc/ganglia/hdp/gmetad.conf<= br>
Search for debug_level and set to above 1.

Setti= ng debug level above 1 should start process in foreground and you can also = look at the log file (/var/log/messages) for errors.
Also, make there are rrd files present for HDFS by looking a say Name= node rrd files under /var/lib/ganglia/rrds.

Some other this to= look for, make sure there is enough space on the mount point where ganglia= is writing files.

You can run
getenforce, it should give you the status (enforcing, disabled or permissiv= e)

If you're in enforcing, you can switch it to permissive = by running
setenforce 0

Fyi, I don't believe that Ambari can run=C2=A0 with seli= nux enabled. It might be better to switch it off once for all by editing /e= tc/selinux/config

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.<= br>
Is there any other way which can handle this issue.

Few graph= s that of hbase are visible but that of HDFS and YARN Mapreduce are Not Dis= plyed

Hi Megh= avi,

Are you able to obtain metrics data by turning off SELinu= x temporarily on Ganglia host ?

Also, are rrd files being written to /var/lib/ganglia/rrds/ ?
