Expected:
The problem view to open up and display any problems that it might have retrieved.

Observations:

CScreenProblem.php
$problems = ($filter['show'] == TRIGGERS_OPTION_ALL)
        ? self::getDataEvents($options)
        : self::getDataProblems($options);
$end_of_data = (count($problems) < $limit + 1);
$problems seems to be returning a boolean instead of an array when getDataProblems is called.

I also have this issue.

$problems is Array, but count() thinks it is bool.

I change the line 286 to:

$end_of_data = (count((array)$problems) < $limit + 1);

And it fixes issue.

But it is possible the is another root of the problem...

However, I have error in the top on this page:

Invalid parameter "/eventid_till": a timestamp is too large.

The same problem after upgrading zabbix instances from version 5.4 and 6.0 to 7.0, while those updated from version 6.4 do not have the same problem

Same here after upgrade from 6.0 to 7.0 and also fixed it in the same way as mentioned by Hawk128. I wished I had found this earlier, it would have saved me some time

 

For people bumping into this; in detail you need to edit “/usr/share/zabbix/include/classes/screens/CScreenProblem.php" and change line 286 from:

$end_of_data = (count($problems) < $limit + 1);

To this:

$end_of_data = (count((array)$problems) < $limit + 1);

 

The problem widget will then load but as mentioned you are still left with the error message "Invalid parameter "/eventid_till": a timestamp is too large.".


Hopefully this will be fixed properly soon.

We have just encountered another issue in one of our instances which is probably depending on this same issue reported here. We are unable to load alert instructions which normally popup when you hover over "duration". Also when clicking the timestamp next to a trigger, a blank page appears where normally you would see the trigger details.

The Apache error log shows a bunch of errors like:

I have tried patching it but doesn't work as new errors come up. Most probably the root case is located in one or more database records since it is down to a timestamp being too large? Any suggestions on how to resolve this? 

Comment by Alexey [ 2024 Jul 23 ]

an update came out - but the problem was not fixed, moreover, the file was overwritten with a new one and it stopped working again. need to edit again

Comment by Geoffrey Timmerman [ 2024 Jul 24 ]

We have rolled back to the 6.0 snapshot we took before upgrade as our production environment needs to be secured. We will retry to upgrade again once we are sure the issue is resolved.

Comment by Alexey [ 2024 Jul 24 ]

in DashBoard the panel with intervals of problems does not open here, I think this is related.
Colleagues, can anyone confirm?

Comment by Geoffrey Timmerman [ 2024 Jul 24 ]

Hi silencess Check the Apache error log for Zabbix (on Debian based systems this is located in "/var/log/apache2/zabbix-error.log") to see what the error is about exactly. But we also encountered this issue with the duration (I've described this in a previous post above). Also clicking the timestamp on the left of the trigger shows a blank page instead of the trigger details.
