Hi Vladimir,
Thanks a lot! The TCP method seems to be working for me.

I don't think it depends on a version. I assume anything 1.4.x will work.

Dear Adrian, Vladimir,
Thank you very much for the answers!
Does it depend on rrdtools/rrdcached version? Which one are you using ?

Another thing to try is to switch over to using TCP for rrdcached connections
since that avoids contention on the rrdcached socket and should avoid some of
the permissions issues. For example I am using following options
OPTS=" -t 60 -w 180 -z 180 -F -s ganglia -m 664 -l 127.0.0.1:9998 -s ganglia -m
777 -P FLUSH,STATS,HELP -l unix:/tmp/rrdcached.limited.sock -b
/var/lib/ganglia/rrds -B -p /var/lib/ganglia/rrdcached.pid
In the gmetad.conf you can then add
rrdcached_address 127.0.0.1:9998

Hi All,
I have updated Gmond/Gmetad to 3.7.2 on our Ganglia server that uses also
RRDCached.
It used to work, and configuration didn't change, but bow metrics do not
get into the graphs anymore.
In the logs there is a lot of messages about permissions, and a new kind
of message about imuxsock thing:
Feb 22 13:18:40 host /usr/sbin/gmetad[3554]: RRD_update
(/var/lib/ganglia/rrds/Grex/__SummaryInfo__/rx_bytes_ib0.rrd): rrdcached:
Permission denied.
Feb 22 13:18:40 host rsyslogd-2177: imuxsock begins to drop messages from
pid 3554 due to rate-limiting
Does anyone know how to fix it? Thank you very much in advance!
I had the same problem (and partially i still have one) ..
So :
1. that "drop messages" message is because of the write errors .. you
can ignore that
2. the problem is with rrdcached .. i tried with making part of group
ganglia, change ownership of rrds to ganglia:rrdcached but had the same
errors ... in the end i had to make the rrds dir 777 and i get rid of errors
3. ganglia web does not function with the rrdcached limited socket so i
had to use the same full socket that gmetad use ... i hope that nothing
bad will happen but i have no other choice...
HTH,
Adrian
