Time Graph View shows nothing

[Moltes]

Hello,
I've upgraded to 1.1.37.
Since I've upgraded Cacti, when I click on the "Time Graph View" button near the graph, nothing is displayed.
I tested using Firefox, Opera, and Internet Explorer without any difference.

Have you any clue about this issue ?

Can you provide a screenshot and the URL being used?

The URL used on the link I click is :
http://<server>/cacti/graph.php?local_graph_id=9332

Are there any logs reporting an error?

[Moltes]

I have seen any error log.

I checked source code in browser.
I also checked flow trafic using wireshark.

I found this Javascript code :

Nothing is shown : no graphs.

I've checked Firebug if any Exception appeared :

I checked into Apache's log files. There are only the call to graph_view.php.
I think it's Javascript that doesn't call to get the RRD images.

The above exceptions all appear to be either jQuery or some other JavaScript library. Not sure why you would be seeing those kinds of errors. Have you tried with no addon's enabled?

[Moltes]

I tried with Internet Explorer (no add-on) and also with Opera (fresh install). Both of them don't show the graph.

[Moltes]

I tested an other function : "Graph Details, Zooming and Debugging utilities" options.
When I click, I've a php error message :

Code: Select all

Notice: Undefined offset: 0 in /usr/share/cacti/graph.php on line 266

Notice: Undefined index: steps in /usr/share/cacti/graph.php on line 268

Is this problem can explain the problem I mentioned first ?

I already reinstalled cacti using yum on CENTOS 7. There was no change.

[netniV]

Have you per chance updated to php 7.2? If so, there are known compatability issues.

[Moltes]

PHP is still in 5.4.16

I've found the problem.
In fact, the person upgraded Cacti before me hasn't executed the upgrade script of version 1.1.17.
This script adds a column in the data_source_profiles_rra table.
I corrected the database.
Since, the buttons are functionning very well.

It can be useful to detect that the mysql queries return error. Is there a log file containing these messages ?

[netniV]

Any MySQL failure is normally recorded into the cacti.log file (which is in the log folder). This is available via the GUI using the Logs tab at the top.

Thanks.
