Your browser won't display it, because it's expecting an image.
So the only place you can find them is the errorlog of your webserver.

You can of course make a errorlog viewer frontend.
In perl you can intercept error messages and tag them with some keyword,
I don't know if you can do that in a shell script. Perhaps
/etc/init.d/functions holds something like that.

Is there a way to debug error messagesd when creating images?  Below is
my sh script/cgi to create the image from rrd data.  My image output is
The image "http://mrtg/cgi-bin/isp/inbound-daily.cgi" cannot be
displayed, because it contains errors.

What could case this issue?


#!/bin/sh


echo "Content-Type: image/png"
echo

rrdtool graph - \
--imgformat PNG \
--interlaced \
--start="-86400" \
--title 'ISP Traffic Inbound' \
--base="1000" \
