I believe I see the error of my ways. I read something about making sure things were relative to the smokeping.cgi script so I had the image cache directory underneath the cgi-bin directory. According to Apache's documentation ANY file underneath a cgi-bin (or marked as a script directory) no matter how many levels down is considered a script and thus will be executed.
<br><br>I moved the image-cache directory to another location and it started working well.<br><br>I am sure I am not the only person lacking CGI expertise wanting to install smokeping so I think a simple addition to the install pages would be nice. Offer up a sample directory hierarchy of what one might look like and mention that you should NOT put the image-cache directory anywhere under the cgi script directory.

I am installing smokeping on request from a manager. I am not a PERL CGI guru which is probably why I am having so much trouble. I find myself trying to HACK the solution as I cannot find the appropriate help I need. I also have little inkling in what smokeping can do. I know it is a latency monitor but when someone like me looks at the config file you get the feeling that you should already know about smokeping inside and out. Okay enough ranting (sorry) just so frustrated. Here is what I have done so far.
<br><br>I believe I have a successful install. I can run smokeping from the command line and I see it running in ps and messages in /var/log/messages but I do not know what it produces. Meaning is there a directory to watch for data it collects? What am I looking for? I have smokeping started/running as root ... I assume this is correct as I did not see mention to the contrary.
<br><br>Then I get to the CGI part. My apache is from a standard redhat rpm install and configured for CGI and runs as the apache user. I have speedy installed because once I activate the cgi I see that speedy is running. When I go to the
smokeping.cgi in the browser I see some things incluing the left hand menu but I do not see the rrdtool and smokeping images that are supposed to be displayed at the bottom of the menu. My apache error log has this:<br>
