SOme graphs not showing up

[Helmut Schneider]

Hi,

Cacti 1.2.7. When displaying all graphs some do not show up. After clicking on details they show up. Where can I start?

Second, when upgrading or installing there is a page during the process showing some recommendations e.g. regading php memory. Can I access that page outside the upgrade process?

Thank you!

Wait for the 1.2.8 release and upgrade right away. There were some issue related to the graph functions that broke a few things. Should be this weekend. Otherwise, you can update to the 1.2.x branch to get the fixes.

Hi,

I still have the issue with 1.2.13.

Sounds like an RRDfile/RRDtool issue. You should paste the Graph Debug syntax to a command line and see if RRDtool segfaults.

No segfault and if I click on "Debug" the graph also shows fine.

I asked you to paste that to a command line and redirect the output to a png file. See what happens.

Okay, that's interesting then. Best to open the debug console and watch for the error messages for the images that do not render. You can go to the Network tab and you will get a 200 result for images that rendered okay, and something other than that for images that fail to render. Most images pages will call graph_json.php these days. Look for the images that either don't come back with a 200 error, or whose results doe not come back as json. That'll give a better clue.

Hm, I'm getting a lot of 401:

but also 200 at the same time:

Sounds like some issue with the web server. Can you compare the 401 headers to the 200 headers and see if the Cookie value between them is the same? Also, edit your php.ini file on the server and sess if session autostart is enabled. If it is, disable it and restart apache.
