[INFO] Black graphs look better than white! :)

[NxTek]

Call me crazy but I like cool looking graphs .. This is a hack that most techies would know how to do, but it requires editing rrd.php. See attached.

Ian - PLEASE allow "skinning" of the Cacti interface. Some of us use the graphs for public view so presentation is important.

[egarnel]

I did a quick scan on my rrd.php, but did not see where to alter the graph background. Could you please provide a code sample?

Thanks

[NxTek]

I added -

-c CANVAS#000000 -c FONT#FFFFFF -c BACK#000000

to the command line which runs rrdtool in rrd.php. If you need more help just let me know!

[egarnel]

I am assuming it goes under function rrdtool_execute: under option 1

if ($log_command == true) {
log_data("CMD: " . read_config_option("path_rrdtool") . " $command_line" "-c CANVAS#000000 -c FONT#FFFFFF -c BACK#000000 ");
}

If memory serves, that's correct. Just make a backup.

Did it work?

[egarnel]

Nope, graphs are gone.... rolling back

[NxTek]

Here's mine -

Code: Select all

  /* basic graph options */
        $graph_opts .=   
                "--imgformat=" . $image_types{$graph["image_format_id"]} . RRD_NL .
                "--start=$graph_start" . RRD_NL .
                "-c CANVAS#000000 -c FONT#FFFFFF -c BACK#000000 --title=\"" . $graph["title_cache"] . "\"" . RRD_NL .
                "$rigid" .
                "--base=" . $graph["base_value"] . RRD_NL .   
                "--height=$graph_height" . RRD_NL .
                "--width=$graph_width" . RRD_NL .
                "$scale" .
                "$unit_exponent_value" .
                "$graph_legend" .
                "--vertical-label=\"" . $graph["vertical_label"] . "\"" . RRD_NL;

[egarnel]

That did the trick! Thanks

[NxTek]

Enjoy.

killer hack!! looks tight! Thanks

[NxTek]

Yes I agree.. Thanks

Is Ian still alive? Any word on the possibility of skinning?

[egarnel]

Check out http://phpsysinfo.sourceforge.net/ It is a skinable system info utility wrtten in php. Perhaps the code could be massaged and an applied to Cacti.. I will try it on a test box next week

[NxTek]

Cool.. I'd be very interested in hearing the results!

I'm still around Were you thinking about skinning graphs or the entire Cacti user interface? Organizationally it would make sense to put the graph skinning functionality in with the graph templates. However I feel that users would object to this since they would probably want to make this kind of change globally. I suppose I could create a new tab under "Cacti Settings" that allowed users to specify various global graph options such as color, background image, etc.

What do you think?

Having a global graph option in Cacti Settings that can allow graphs to be skinned is a great idea. By default all graphs would confirn to this, however, it would be cool, if possible, to over-ride this in the graph template section for specific instances.

As well as skinning font / colour, a link to a backgroud image would be great (especialy to give clients that special feeling)

As an aside, adding functionality like this to make it simple for users to contribute (and show off) can only help the community spirit for this exellent app.
