Hi all,
In an attempt to improve the performance (previous email thread with subject Performance Issue - High CPU with 'mysqld'?), I'm trying to use 'rrdcached' on a new setup (version 18.9.9428 (9th September 2018) with the following configuration:
===
sjc-observium-1:/etc/init.d# cat rrdcached <...snipped...> # Path to the apachectl script, server binary, and short-form for messages. rrdcached=/usr/sbin/rrdcached prog=rrdcached pidfile=/var/run/rrdcached/rrdcached.pid sockfile=/var/run/rrdcached/rrdcached.sock lockfile=/var/lock/subsys/rrdcached RETVAL=0 <...snipped...>
-
sjc-observium-1:/etc/sysconfig# cat rrdcached <...snipped...> RRDCACHED_USER="apache" OPTIONS="-w 1800 -z 1800 -f 3600 -s apache -l unix:/var/run/rrdcached/rrdcached.sock -j /var/tmp -m 664 -F -b /opt/observium/rrd -B" SOCKPERMS=0660 <...snipped...>
-
sjc-observium-1:/usr/lib/tmpfiles.d# cat rrdcached.conf d /run/rrdcached - apache apache sjc-observium-1:/usr/lib/tmpfiles.d#
-
sjc-observium-1:/opt/observium# grep rrd config.php //rrdcached #$config['rrdcached'] = "unix:/var/run/rrdcached/rrdcached.sock"; <<<====== will un-comment once rrdcached is configured and running sjc-observium-1:/opt/observium#

Any suggestions or docs/links showing how it can be resolved?
Thanks.
