rrdtool graph examples

I've a rrdtool database, with which I'm used to print the MAX, Min, Average value. There are two kinds of arguments. RRDtool 1.x - Round Robin Database. This is not used for dynamic data but instead to create a hard line horizontally across the Cacti graph. An example works best: in the Netherlands we have a time offset of one hour, plus an extra hour during the summer. For example, use 3 to display the y-axis values in k (Kilo, 10e3, thousands), use -6 to display the y-axis values in u (Micro, 10e-6, millionths). It is very easy to create your first simple graph. This how-to will show the quickest way to generating your first graphs while explaining the options used. By default, rrdtool graph calculates the width of one pixel in the time domain and tries to get data from an RRA with that resolution.

The graph method with its various "graph/draw", "graph/color", "graph/font" are notable examples. You will notice, that rrdtool automatically extends the y-axis despite the given –upper-limit! For viewing the graphs add a symlink in /www which points to /tmp/rrd: cd /www ln -s /tmp/rrd/ traffic . They are used to plot all kind of data against time in a very easy way which is why they are used a lot in all kind of applications. And, as a band-aid, you can disable strict mode in these situation by setting the strict parameter to 0 in RRDTool::OO 's constructor call: rrdtool graph temp_graph.png: generate the graph in a file called temp_graph.png in the current directory-w 785 -h 120 -a PNG : width 785, height 120, PNG format –slode-mode: smooth line –start -604800 –end now: graph begins 7 days ago (604800 seconds) and ends now –vertical-label “temperature (°C)”: vertical axis label rrd_version — Gets information about underlying rrdtool library rrd_xport — Exports the information about RRD database rrdc_disconnect — Close any outstanding connection to rrd caching daemon If all was setup correctly, you can access the server with Perl sockets, tools like netcat, or in … This module is compatible only with rrdtool-1.2.30-win32 right now; 1.2.30 is the last win32 build officialy distributed by Tobias Oetiker Its main purpose is to create a nice graphical representation, but it can also generate a numerical report. Variable names (vname) must be made up strings of the following characters "A-Z, a-z, 0-9, -,_" and a maximum length of 255 characters.When picking variable names, make sure you do not choose a name that is already taken by an RPN operator. rrdtool graph needs data to work with, so you must use one or more data definition statements to collect this data.

We are east of Greenwich so we are ahead of UTC time by either one or two hours. For instance, if your RRD has an RRA with a resolution of 1800 seconds per CDP , you should create an image with width 400 and time span 400*1800 seconds (use appropriate start and end times, such as "--start end-8days8hours" ). This example graph memory usage. It also has the capability to reduce its accuracy once the time increases. For example, in SNMP replies, memory consumption values are usually specified in KBytes and traffic flow on interfaces is specified in Bytes. For example, the value 100 will result in graphs that have a upper bound of 100 or more. Be careful not to monitor too many hosts since rrdtool graph needs a lot of time. You may not be familiar with the term RRD graph, but if I show you one, you probably recognize them instantaneously. If the default grid is not what you want, use the --x-grid parameter ("rrdtool graph --x-grid ... define the base grid. Cons : I personally don't like very much graphes produced by rrdtool graph.
