change the default graph type from png to jpg

[viper99]

Is there a way to change the default behavior of Cacti to make the graphs jpg's instead of png's?

Please login as admin. See entry Graph Templates in the menu bar at the left, select it. See the list of all Graph Templates. Select those Templates, you want to change, one by one. Having selected a template, please change the Image Format (one of the items on the lower half of the screen)

ok thanks. I don't know how I missed that earlier..will that take affect on all existing data or will I have to modify my existing data to get them in gif format?

Instand change, that. As each graph gets generated on the fly. That's what templates are for, eh

FYI, only gif and png are supported. I'm not even sure RRDTool supports jpg.

[gandalf]

Oops, sorry for that. Please find from man rrdgraph

Code: Select all

           [-a│--imgformat PNG│SVG│EPS│PDF]

           Image format for the generated graph. For the vector formats you can choose among the standard Postscript fonts
           Courier-Bold, Courier-BoldOblique, Courier-Oblique, Courier, Helvetica-Bold, Helvetica-BoldOblique, Hel-
           vetica-Oblique, Helvetica, Symbol, Times-Bold, Times-BoldItalic, Times-Italic, Times-Roman, and ZapfDingbats.

Conclusion: sorry, no jpg here.
BTB: even GIF is not reported here (rrdtool 1.2.13 running)

After changing the graphs to gif I now have no graphs in my system. They all show up as a red x. Any ideas on that?

[rony]

Yes, rrdtool you have installed does not have gif support. Honestly not a big surprize.

Please post your rrdtool's version. Then, select the red x, then the wrench and post the whole rrdtool graph statement. And please read my last post above (sorry for that, again)

Run that from the command line, what is the error message rrdtool gives you?

Bingo, looks like you have to use PNG format.
