More graph trouble, RRD have files but only red X displays

[jd5646]

I competed the install of cacti yesterday. After working out several problems I was able to get the cacti interface up and to get the poller to begin creating RRD files. I still only receive the dreaded red X indicating that a picture can't be displayed in Internet Explorer.

I'm using the following versions of the tools involved..
rrdtool-cygwin-1.2.4
mysql-4.1.14-win32
php-5.0.5-Win32
cacti-0.8.6g
cacti-cactid-0.8.6e
net-snmp-5.2.1.2-1.win32

I'm attaching a copy of output from the cacti log file. (I've got it logging everything right now so there's a lot there) I'll also attach a copy of output from the poller.php.

I'll be glad to get some help!

Can't really offer a whole lot of advice since I'm in the same boat but I know that BSOD or whoever reads this will want a graph debug output.

Graph Management -> Click on a Graph -> Click "Turn on Graph Debug Mode"

Here's a copy of a graph debug output....

1) you've got a lot of data sources which are broken (hence the output of U in the debug) which you should fix.

2) Make sure your web user account has execute rights on cmd.exe

Like Magic... It was permissions for user IUSR. I thought that I'd set those permissions to permit read and execute yesterday but found today that they are set to deny. I now see graphs with data. THANK YOU!

What should I do about the broken data sources you see? Can you suggest something that will correct this?

Thanks again for the help so far...

The data sources with dsname traffic_out/traffic_in can often be fixed by clicking on the green circle next to SNMP - Interface Statistics for the devices having problems.

If the indexes for the interfaces are constantly changing, you might want to change the re-index method to 'verify all fields', but this will result in a performance hit.
