Requested: company logo in background of graph.

[christiaan]

Is it posible to have a (small) picture in a corner of the graph? i like to put the company logo in.

In theory rrdtool is able to add some bitmap to your graph as a background or overlay (-B and -O options). However I couldn't get it working (acceptable bitmap formats are only .gd files). If you are willing to try and you succeed let me know please. To have it working in cacti you would need to add proper rrdtool command option in "rrdtool_function_graph" function (it is in "lib/rrd.php" file).

Someone has got this working yet?

Nope, but if you made a working patch I bet they would incorporate it.

Please note that the -B and -O do not function in RRDtool 1.2.x as described above in this 2.5 year old post. The only option available in 1.2.x is the -W option that places a text watermark on the bottom of the graph centered.

Certain customizations could be made to incorporate a background image, but it would have to come from Tobi.

Hi All!!

I'm trying to add a watermark image as background of the graphic, but I still have problems.

I study the code and the data dump by RRDTool is not compatible with data received by PHP-GD.

Someone has been working on this? or someone give me more info about this topic. Or I totally fucking because that depends on rrdtool?

Excuse my English but i speak spanish and y try to translate with Google.

Saludos!!

It depends on rrdtool, yes. The required option is currently not supported by cacti. Create a feature request for this

Hi,

i'm interested in watermarking all my graphs with the --watermark string attribute but wondered which file i could edit so that it will default this on all generated graphs. i guess im looking at something in \lib\ rrd.php maybe?

any help or direction?
thanks.

Yes, that would be the file to be touching.

would this mean that it will be apart of the new 0.8.7c release?

..cacti/lib/rrd.php (round line ~730)

Code: Select all

/* basic graph options */
	$graph_opts .=
		"--imgformat=" . $image_types{$graph["image_format_id"]} . RRD_NL .
		"--start=$graph_start" . RRD_NL .
		"--end=$graph_end" . RRD_NL .
		"--title=\"" . str_replace("\"", "\\\"", $graph["title_cache"]) . "\"" . RRD_NL .
		"$rigid" .
		"--base=" . $graph["base_value"] . RRD_NL .
		"--height=$graph_height" . RRD_NL .
		"--watermark=COMPANYNAME" . RRD_NL .
		"--width=$graph_width" . RRD_NL .
		"$scale" .
		"$unit_value" .
		"$unit_exponent_value" .
		"$graph_legend" .
		"--vertical-label=\"" . $graph["vertical_label"] . "\"" . RRD_NL;

this worked perfectly placing the watermark text on all graphs like stated in the rrdtool reference guide.

[-W|--watermark string]
Adds the given string as a watermark, horizontally centred, at the bottom of the graph.

i wonder if there is a way to easily set the postion/add bold/different font etc... to the watermark only?
