Graphs not generating on Windows 2008 [x64] / IIS7 / PHP 5.3

[yar0]

Hi,

I've installed Cacti 0.8.7i on Windows 2008 [x64] (IIS7 + PHP 5.3).
After hard installation and configuration cacti started gathering data to rrd files.
But graphs didn't shows.
I've checked, that rrdtool generate graphs from command line (I get command from cacti debug).
I found problem in file lib/rrd.php - line 98 (in function rrdtool_execute).
PHP execute rrdtool.exe command to get graph.

Code: Select all

	
if (!is_resource($rrdtool_pipe)) { 
		session_write_close(); 
		$fp = popen(read_config_option("path_rrdtool") . escape_command(" $command_line"), $pipe_mode);
		if (!is_resource($fp)) {
			unset($fp);
		}
	}

But $fp handler did output nothink. The problem is (propably), because popen function starts that process in other environment, output from that command is not back to $fp handler. You have to put "start /b " before the command:

Code: Select all

$fp = popen("start /b " . read_config_option("path_rrdtool") . escape_command(" $command_line"), $pipe_mode);

I don't know, if this correct solution, but works.
Of course developers should check system version, and so on, and so on. But for me it works and graphs are showing up.

Please, can anyone report this as a bug (I don't know how to put it on that bugzilla page).

How did you install cacti? manually or used the installer?
Before you made the code change, what error did you get when graphs were not rendering? You sure it wasnt a NTFS permissions problem?
