Thank you for advice! but after switching to tcp now i have a problem with this :
Feb 26 18:23:55 monitor /usr/sbin/gmetad[16225]: RRD_update (/export/ganglia/rrds/__SummaryInfo__/multicpu_wio4.rrd): absolute path names not allowed when talking to a remote daemon i have this structure for options : OPTS="-b ${RRDS_DIR} -B -R -F -j ${RRDCACHED_JOURNAL_DIR} -w ${RRDCACHED_WRITE_TIMEOUT} -z ${RRDCACHED_WRITE_DELAY} -f ${RRDCACHED_WRITE_OLDTIMEOUT} \ -t ${RRDCACHED_WRITE_THREADS} \ -s ${RRDCACHED_USER} -m ${SOCKPERMS} -l ${SOCKET1} \ -s ${RRDCACHED_USER_LIM} -m 777 -P FLUSH,STATS,HELP,INFO -l ${SOCKET2}" RRDCACHED_USER* is ganglia and the PID file is set up in the init file... in the end i had to return to my old setting and because the graphs are not seen by ganglia-web if limited sock is used, i had to use the full sock.. > In the gmetad.conf you can then add > > rrdcached_address 127.0.0.1:9998 this did not worked, i had to use : RRDCACHED_ADDRESS=127.0.0.1:9998 btw : why is this setting on different file than gmetad.conf? Couldn't/shouldn't be in gmetad.conf? Thank you!
