Missing Custom Data

[jackouille]

When I try to create a graph based on my templates I'm now always prompted to provide Custom Data such as shown within the attached pic.

Previously (meaning som years ago) Custom Data were already displayed and empty and I was able to create graphs.

What could be the root cause and how can I solve it ?

The graphs created some years ago are still working and templates were not changed.

Did you upgrade cacti?

[jackouille]

Currently running version 1.2.25 under Rocky 9 with PHP 8.3.3

[jackouille]

Version 1.2.26 not available via yum. I already ask the "packager" twice via email but no answer yet.

[macan]

is any warning/error in log after your add graph operation?
I think some similar bug was fixed some time ago, but I can't find it.
1.2.26 or actual github 1.2.x branch version is better than 1.2.25

[jackouille]

Nope, I simply can't add new graphs using my own templates. Default graphs works fine.

I update one time manually from Github but then had unresolved issues, that's why I would prefer to wait for the official package.
Are you maybe in touch with the packager ?

[jackouille]

I just tried and upgrade version 1.30 (Dev) but still having the issue so I rolled back.

Another suggestion ?

[jackouille]

Is there one file to be updated in order to solve this issue quickly ?

[jackouille]

Ok I have duplicated my current instance for performing deeper tests, what should I change now?

Grab the 1.2.26 from http://www.cacti.net/info/downloads
Install successfull :
Date Thu, 07 Mar 2024 22:46:59 +0100
Cacti Version 1.2.26
Cacti OS unix
RSA Fingerprint 0e:ce:94:ea:9d:e9:42:d3:c9:d2:ac:a7:5a:fc:fa:ad
NET-SNMP Version NET-SNMP version: 5.9.1
RRDtool Version Configured 1.7.2+
RRDtool Version Found 1.7.2

But still having the same issue : prompted to provide Custom Data, here for Template: Interface - Trafic, but don't know which value I shall enter. Proposed values are empty and no choice proposed.

Got the following warning on Log:

Could you please try to create a graph from the following template ?
And tell me if it works from your side ?

[jackouille]

Or is there a simply way to duplicate a graph (a graph, not e template) that already works ?
That could be a workaround, what do you think ?

[macan]

1.3.0 is develop version. It isn't for production now.

Go to Management-> Data Sources -> choose any of working datasources and you will see what is correct Index Type, Index Value a Output Type ID. I think that you have old template which is incompatible with new cacti.

[jackouille]

In the meantime I found a workaround (on version 1.2.25) : duplicate the graph template then while prompted for the field I simply put 1 in each of them, graph is also created but the displayed popup doesn't look like exactly as others, it's simply in black and white. If you need it I can provide you a picture next time I create one.
So these fields are useless but you are asking for them, what's the added value ?

Run the database_audit.php and find the issues. You have a non-nullable field that was changed recently to fix this. So, it looks like you upgrade did not work as expected. Report the output of the database_audit.php.
