Hi Meghavi, You should be able to debug this by editing, /etc/ganglia/hdp/gmetad.conf
Search for debug_level and set to above 1. Setting 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 Namenode 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. -Sid On Thu, Jun 12, 2014 at 6:41 AM, Meghavi Sugandhi <[email protected]> wrote: > > 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. > > /var/log/messeges > > Jun 12 17:29:47 INBBRDSSVM50 nagios: SERVICE NOTIFICATION: sys_logger;
