Can I create a graph as an HTML image?
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.

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=.........>

Doh! I had the 'img src' and the showgraph, but just didn't put the two together!
Many thanks for that. Phew, that saves an awful lot of messing around.

Yep! Armed with that, it's not too difficult to script and pre-gen various RRD graphs for reports and other purposes.
