showgraph.sh *does* produce a png image. Click through the trends column, click through a graph, look at the page source. You'll see
<img src="/xymon-cgi/showgraph.sh?host=server.domain.com&color=.........>

Hello,
Using Xymon 4.3.7, does anyone know if it is possible to create a graph as an HTML image? That is, so that I can use '<IMG SRC...>' in a web page.
I have had a look at 'showgraph.sh', but that seems to create a link to a page which then contains just the graph. I want the graph/image, not a link to it. Even using the '--save' option
Our old Big Brother/MRTG system created PNG images of various things (which admittedly was a big drain on the system), and we could then create web pages which simply loaded whatever graphs/images we wanted. I'm now trying to do something similar but using Xymon/RRD.
Anyone any ideas about this?
(Current thoughts are perhaps to use PHP with rrdgraph to create the image. However, I then have to fiddle with the format of the image unless I can parse the graphs.cfg file.)
John.
