Waterfalls not showing up in results directory

WebPageTest Private Instances
1

I apologize if this is posted elsewhere, I have not been able to find an answer.

I have WPT 2.12 installed on Windows XP with Apache 2.2.25 and PHP 5.4.21. When I run tests, the waterfall shows properly, but when I look in the results folder, I do not see it. Yes, GD is installed properly (as far as I can tell).

Here is the result of install/index.php

And these are the files I see in the results directory:
1_devtools.json.gz
1_IEWPG.txt.gz
1_IEWTR.txt.gz
1_progress.csv.gz
1_report.txt.gz
1_screen.jpg

1_screen_render.jpg

test.job
testinfo.ini
testinfo.json.gz

Any help is greatly appreciated!

The waterfalls are generated dynamically by PHP and returned directly to the browser - they are never stored on disk. If you want the images you should request them through the API interface.

Thank you very much for your response. I should have mentioned initially that I am using the API, using the test URL, the images portion of XML payload I get back from a test looks something like the following, but the URL to the waterfall does not work.

[b] http://foo/results/13/11/06/DG/20/1_waterfall.png [/b] http://foo/results/13/11/06/DG/20/1_connection.png http://foo/results/13/11/06/DG/20/1_optimization.png http://foo/results/13/11/06/DG/20/1_screen.jpg http://foo/results/13/11/06/DG/20/1_screen.png

I currently have code that utilizes the public instance and the links to waterfalls in the xml are valid. I am updating the URLs in the code to use the new private instance, but I am hitting this roadblock.

Do you have mod_rewrite enabled? Those are the “friendly” version of the URLs that get rewritten to point to waterfall.php with query params. It should be auto detecting the lack of mod_rewrite and giving you the direct URLs when it isn’t present but that doesn’t always happen.

Thanks for the suggestion. I checked httpd.conf and the module is un-commented.

LoadModule rewrite_module modules/mod_rewrite.so

I’m seeing this same issue. I also have mod_rewrite enabled.

Where are you doing the rewrites? Maybe i missed a part of the install.

Do you have anything special in your httpd.conf or php.conf file for apache?

Make sure you have the .htaccess file. For some reason, i didn’t have it. That’s where all the rewrites live. I found it on github.
