When reading the graph remember that new data is on the right and the oldest data is on the left. We will being putting all of the files into a working directory we made up called, "/tools/rrdtool/latency/".
The rrdtool lines in the file are one command, but we have put line breaks ( \ is a line break ) in to create multiple lines so it is easier to read and explain.RRDtool is a graphing utility made by Tobi Oetiker and released under the terms of the GNU General Public License (GPL).It is simply a program that takes data sets you collect and graphs [email protected]# cat initialize_### change to the script directory cd /tools/rrdtool/latency/ rrdtool create latency_\ --step 60 \ DS:pl: GAUGE:120:0 \ DS:rtt: GAUGE:120:000000 \ RRA: MAX:0.5:00 \ rrdtool create latency_-- here we are calling the rrdtool binary and telling it to "create" the rdd database we have named "latency_db.rrd".This file is created in the current working directory.This script will make a rrd database called "latency_db.rrd".
This is the file that will be updated and hold all of your data. The following scrollable window contains the command we used to make the rrd file.
Once the graph is made it can be copied to a web directory like, "/var/www/htdocs/" for easy viewing through our web server.
To use RRDtool you must first initialize the database.
There are three(3) basic steps to setting up RRDtool and graphing your data sets. Please make note that the syntax of rrdtool changes with the package version.
We highly suggest using RRDtool v1.2.x which require very few dependancies compared to v1.4.x.
The database will always have the same amount of data points throughout its lifetime.
