Graphs not rendering in UI

[laszlo]

I'm using:
PHP 5.1.2 - using the isapi module in IIS 5.1
rrdtool 1.2.12 from the cacti.net site
MySQL 5.0.18
Windows XP with SP2
net-snmp 5.2.2

I followed the windows installation instructions, set my RRD_DEFAULT_FONT, MIBDIRS, etc, so no more errors and warnings are being emitted.

I view a graph in debug mode and I get this:

RRDTool Command:

RRDTool Says:

If i paste that command into a cygwin window and run it with the output redirected to a PNG file I get the correct graph with the fonts and everything working (attached). I tried messing with all the permissions, I even went as far as giving 'Everyone' full control on cmd.exe, the php dir, the cacti dir, etc. After giving access to cmd.exe it started to just hang instead of giving me the errors above.. I'm guessing this is just a permission problem of some sort but I can't figure it out. What are the correct permissions for each item, and what user should I be running the poller.php as?

Thanks in advance,
Laszlo

I removed the extra permission I added to cmd.exe and the graphs are now rendering. I'm still curious what the 'proper' settings are though

The proper settings are that your web user account, typically IIS_USR needs read/execute rights on cmd.exe and rrdtool.exe.

Thanks!
