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 Vladimir 02/23/2016 u 09:34 AM, Adrian Sevcenco je napisao/la: On 02/22/2016 10:32 PM, Grigory Shamov wrote: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...
