0.4.0 shows hosts, but not graphs

[pi-xi]

Hi,

I'm using 0.4.0 collectd-web on SL6 with collectd 4.10.3. The
collection.conf in /etc/collectd/ contains only line datadir: "/var/
lib/collectd/" which indeed hosts the rrd files under /var/lib/
collectd/myhost/. I've unpacked the collectd-web git snapshot to a
directory and set up the following settings in apache:

<Directory "/storage0/www/collectd/">
SSLRequireSSL
Order deny,allow
Deny from all
Allow from 192.168.1.0/24
</Directory>

Alias /stats /storage0/www/collectd/

When I open https://myserver/stats in the browser, I can select myhost
in the hosts list, and it lists all the enabled plugins as expected.
Whenever I click a plugin, it just briefly shows a loading circle and
then displays the hostname but no graph (not even an empty graph).

I have checked that the rrd files really contain valid data by
creating images with drraw directly. I've also ran the following query
in the console:

./collection.modified.cgi action=show_graph host=myhost plugin=memory
timespan=day type=memory format=SVG > test.svg

and indeed a valid looking SVG output is produced (and when I remove
the Content-Type: image/svg+xml; charset=ISO-8859-1 from the
beginning, I can open it in my browser and see the graph).

check_deps.pl output is:

Carp looks ok
CGI looks ok
CGI::Carp looks ok
HTML::Entities looks ok
URI::Escape looks ok
RRDs looks ok
Data::Dumper looks ok
JSON looks ok

Do you have any idea of where to start debugging this?

Hi, 

everything seems alright, but did you check that your apache user has the same priviledges as you have?
