If you are using ‘native’ MRTG (without the RRD backend) then you do not have the data and there is nothing you can change to make it so. The RRD and MRTG storage format are ‘round robin’, summarising and expiring data automatically after a preset amount of time.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>The default RRD file generated by MRTG will have only two days’ data at 5min interval, though you can subsequently use the ‘rrdtool resize’ command to extend the relevant RRAs (number 0 and 1). You can also use the RRDRowCount[] directive in the MRTG file to ensure that RRD files will be created with additional rows, though this only affects newly created files, not pre-existing ones.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Next, in order to generate a 3-day graph, you need a frontend that is programmed to do so. The 14all and mrtg-rrd frontends only generate the normal 1-day graph.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>The Routers2 frontend has an option to generate a 2-day graph – if the underlying RRD file has large enough RRAs (older MRTG-generated files do not). You can also ask for a 1week graph with ‘half data width’ which is approximately 3 days. To get this, select the ‘Weekly’ graph, but use the ‘stretch’ data type (t). If you have enough underlying data in your 5min RRA this will be used for the graph, else it will use the 30min data form the Weekly RRA.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>The only real way to get what you want is to use something like rrdcgi and create the graph commandline yourself. In this case, you can generate a graph in whatever format you want, provided of course that the data are within the RRD.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Steve<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal><b><span style='color:#1F497D'>Steve Shipway<o:p></o:p></span></b></p><p class=MsoNormal><span style='font-size:10.0pt;color:#1F497D'>s.shipway@auckland.ac.nz<o:p></o:p></span></p></div><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> mrtg-bounces+s.shipway=auckland.ac.nz@lists.oetiker.ch [mailto:mrtg-bounces+s.shipway=auckland.ac.nz@lists.oetiker.ch] <b>On Behalf Of </b>Bob Reiber<br><b>Sent:</b> Monday, 17 March 2014 8:22 a.m.<br><b>To:</b> mrtg@lists.oetiker.ch<br><b>Subject:</b> [mrtg] can i change the 1 day graph to show three days<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-US>I like the 5 minute graph but want it to display 3 days worth of data.
