Hi Fabio,
You can change default RRD storage settings? in
common-services/GANGLIA/3.5.0/package/files/gmetadLib.sh? line 120 before
ganglia server start
If you want to change sampling rate to 5 second, you would have
?
RRAs "RRA:AVERAGE:0.5:1:732" "RRA:AVERAGE:0.5:24:244" "RRA:AVERAGE:0.5:168:244"
"RRA:AVERAGE:0.5:672:244" \
"RRA:AVERAGE:0.5:5760:374"
instead of
RRAs "RRA:AVERAGE:0.5:1:244" "RRA:AVERAGE:0.5:24:244" "RRA:AVERAGE:0.5:168:244"
"RRA:AVERAGE:0.5:672:244" \
"RRA:AVERAGE:0.5:5760:374"
RRA:AVERAGE:0.5:1:732? means 732 samples per 1 hour
BR,
Dmytro sen

Subject: Permanent changes to Ganglia config (how to)
Hi everyone,
I was trying to change the Ganglia sampling rate (let's say from 15 to 5
seconds). I made some changes on the ambari-server node in the file
/etc/ganglia/hdp/gmetad.conf but, when I restart the Ganglia service in Ambari,
it is reverted to the original one.
Then I modified the file /usr/libexec/hdp/ganglia/gmetadLib.sh, which looks
like the generator of the gmetad.conf, but even this file is then reverted to
the original one.
How can I make a permanent change to the gmetad.conf? Will this changes be
broadcasted to all the other nodes?
Thanks a lot
Fabio
