I'm Ambari v.1.2.4 user.
I want to change period on 2hr graph of ganglia from 6min to 5min.
So I changed /etc/ganglia/hdp/gmetad.conf
(remove # and RRA:AVERAGE:0.5:24:244 to RRA:AVERAGE:0.5:20:244)
RRAs "RRA:AVERAGE:0.5:1:244" "RRA:AVERAGE:0.5:20:244" "RRA:AVERAGE:0.5:168:244" "RRA:AVERAGE:0.5:672:244" "RRA:AVERAGE:0.5:5760:374"
And then, I restart ganglia by Ambari but there was no change..
I tried "service gmetad start" command on ganglia server, but it also doesn't work.
What should I do to change ganglia graph period??
