Installation on clonweb to /www as root:
mkdir /www/rrdtool1.2.23 chown mrtg:mrtg /www/rrdtool1.2.23 cp /usr/local/downloads/rrdtool-1.2.23.tar.gz /usr/local/src cd /usr/local/src gunzip rrdtool-1.2.23.tar.gz tar xvf rrdtool-1.2.23.tar cd rrdtool-1.2.23 ./configure --prefix=/www/rrdtool1.2.23 make make install
Add following lines to mrtg.cfg to help MRTG to find rrdtool:
LogFormat: rrdtool PathAdd: /www/rrdtool1.2.23/bin LibAdd: /www/rrdtool1.2.23/lib/perl/5.8.5
NOTE: I did not do it but if you want to install to /usr/local does not create anything in /www and configure as following:
./configure --prefix=/usr/local
To see rrd file's contents use 'rrdtool', for example:
/www/rrdtool1.2.25/bin/rrdtool fetch /www/mrtg2.15.2/share/logs/server-cpu.rrd AVERAGE
IMPORTANT: after switching to rrdtool, mrtg will NOT update web graphs any more; to do that CGI scripts must be used. Some examples of those scripts can be found at [1] and [2]. I installed mrtg-rrd-0.7. Script was installed into Apache's cgi-bin directory and slightly modified by setting actual mrtg location including RRDs.pm:
use lib '/www/rrdtool1.2.25/lib/perl/5.8.5';
BEGIN { @config_files = qw(/www/mrtg2.15.2/etc/mrtg.cfg); }
Also, option '--lazy' was removed to enforcr every minute update. Also old *.png were removed, they were owned by 'mrtg', new *.png will be written by 'apache'. To see graphes type http://clonmon.jlab.org/cgi-bin/mrtg-rrd.cgi.
