Hi, I am generating graphs from rrdtool using a cgi script. When an error occurs I need to return an image that contains the error message instead of the graph (it needs to return an image as that is what is being requested - ie: from an <img> tag).
I currently do this by having rrdtool parse an empty rrd file (ie: all NaNs) to generate a blank graph and using a COMMENT command to display the error in the image. I found that I could not get rrdtool to generate a graph without passing it an RRD file. I would rather be able to just generate an image containing the error text only, and not bother about faking an empty graph from a dummy RRD file. Is this possible?
