Speeding up graphs with RRDCacheD

Ubuntu / Debian
The instructions for Ubuntu 12.x and Debian 7.x / 6.x are:- Make sure that you have the latest version of rrdtool and rrdcached:
- Edit /etc/default/rrdcached:
OPTS="-l unix:/var/run/rrdcached.sock -s andrisoft -m 774 -w 3600 -f 7200 -F -b /var/lib/rrdcached/db/"
- Enable rrdcached:
/etc/init.d/rrdcached start update-rc.d rrdcached defaults 99
- Add the following commands to /etc/rc.local and execute them afterwards:
chown andrisoft:www-data /var/run/rrdcached.sock chown andrisoft:andrisoft /var/run/rrdcached.pid chmod 770 /var/run/rrdcached.sock
- Add unix:/var/run/rrdcached.sock to the RRDCache field in Configuration » General Settings » Graphs & Storage. The deletion of existing IP graphs is not needed.
apt-get install rrdtool apt-get install rrdcached
while true; do clear ; echo STATS | socat - /var/run/rrdcached.sock; sleep 1; done*NOTE* The ownership and permissions of the rrdcached.sock file resets with every service restart. Make sure to execute /etc/rc.local every time you restart the service. When the system reboots, the rc.local file should be executed automatically.
CentOS 6 and Red Hat 6
The instructions for CentOS 6.x and RedHat 6.x are:- Make sure that rrdtool and rrdtool-perl are installed and are both version 1.4.3 or higher
- Check rrdtool version:
rrdtool
Output should be:RRDtool 1.4.7 Copyright 1997-2012...
- If you have a lower version than 1.4.3, remove the previous installment of rrdtool and all its dependencies:
rpm -e rrdutils rrdtool-perl rrdtool
- Download and install rrdtool and perl-rrdtool version 1.4.7
wget http://pkgs.repoforge.org/rrdtool/perl-rrdtool-1.4.7-1.el6.rfx.x86_64.rpm wget http://pkgs.repoforge.org/rrdtool/rrdtool-1.4.7-1.el6.rfx.x86_64.rpm rpm -i perl-rrdtool-1.4.7-1.el6.rfx.x86_64.rpm rrdtool-1.4.7-1.el6.rfx.x86_64.rpm
- Check the current version of rrdtool again and make sure it is 1.4.3 or higher.
- Check rrdtool version:
- Edit /etc/sysconfig/rrdcached:
OPTIONS="-l unix:/var/rrdtool/rrdcached/rrdcached.sock -s andrisoft -m 774 -w 3600 -f 7200 -b /var/rrdtool/rrdcached" RRDC_USER=andrisoft
- Set proper permissions:
chown andrisoft:andrisoft /var/rrdtool/rrdcached
- Enable rrdcached:
/etc/init.d/rrdcached start chkconfig --level 34 rrdcached on
- Add the following commands to /etc/rc.local and execute them afterwards:
chown andrisoft:apache /var/rrdtool/rrdcached/rrdcached.sock chown andrisoft:andrisoft /var/rrdtool/rrdcached/rrdcached.pid chmod 770 /var/rrdtool/rrdcached/rrdcached.sock
- Add unix:/var/rrdtool/rrdcached/rrdcached.sock to the RRDCache field in Configuration » General Settings » Graphs & Storage. The deletion of existing IP graphs is not needed.
while true; do clear ; echo STATS | socat - /var/rrdtool/rrdcached/rrdcached.sock; sleep 1; done*NOTE* The ownership and permissions of the rrdcached.sock file resets with every service restart. Make sure to execute /etc/rc.local every time you restart the service. When the system reboots, the rc.local file should be executed automatically.
CentOS 7 and Red Hat 7
The instructions for CentOS 7.x and RedHat 7.x are:- Install the latest version of rrdtool:
yum install rrdtool rrdtool-perl
- Create the rrdcached service file.
nano /usr/lib/systemd/system/rrdcached.service
- Type the following lines within:
[Unit] Description=RRDCacheD for Andrisoft [Service] Restart=always User=andrisoft PermissionsStartOnly=yes ExecStartPre=/bin/mkdir -p /var/rrdtool/rrdcached/ ; /bin/chown andrisoft:andrisoft /var/rrdtool/rrdcached ExecStart=/usr/bin/rrdcached -l unix:/var/rrdtool/rrdcached/rrdcached.sock -s andrisoft -m 774 -w 3600 -g -p /var/rrdtool/rrdcached/rrdcached.pid ExecStartPost=/bin/sh -c "/bin/sleep 4; /bin/chown andrisoft:apache /var/rrdtool/rrdcached/rrdcached.sock ; /bin/chown andrisoft:andrisoft /var/rrdtool/rrdcached/rrdcached.pid ; /bin/chmod 770 /var/rrdtool/rrdcached/rrdcached.sock" [Install] WantedBy=multi-user.target
- Save and Exit.
- Start the rrdcached service
systemctl enable rrdcached systemctl start rrdcached
- Add unix:/var/rrdtool/rrdcached/rrdcached.sock to the RRDCache field in Configuration » General Settings » Graphs & Storage. The deletion of existing IP graphs is not needed.
