rrdtool.php line 303 error.

[alexcf]

Has anyone worked out how to fix this rrdtool.php error, line 303 yet... I get this when I try to use the 95th percentile. Its getting quite fustrating, mikepont sent me a step by step screenshot guide in an email, just to make sure I wasn't doing it wrong, but I'm going round and round in circles, I'd really appreciate some help.

Regards,

Alex.

I am also having this problem with the 303 error.

Let's try the debugging route. Can either of you replace your 'include/rrd_functions.php' with the following file:

http://www.raxnet.net/downloads/patches ... ns.php.txt

After doing that, click on a 95th percentile graph and click "View Source" under it. You should see a lot of output which you can paste here inside phpBB code tags. It also might be helpful to include the 95th percentile variable that you are using.

I actually tracked down and fixed this problem. The problem was in the input passed to pow(). In the newer versions of php pow() seems to be a bit more strict on what it takes as input. You can fix the problem by casting the second argument to pow as a float, so change

Code: Select all

$line = ($matches[1][$j] * (pow(10,$matches[2][$j])));

to

$line = ($matches[1][$j] * (pow(10,(float)$matches[2][$j])));

on line 303 of rrd_functions.php.

Hope that fixes your problem, it fixed mine.

Thanks for taking the time to find this! The PHP version on my development box is still 4.1.2... time to upgrade. Sounds like a Saturday project to me
