Zabbix 7.0.1 to 7.0.2 Graphs Time Intervals not showing

[snetgh]

After upgrading to zabbix 7.0.1 to 7.0.2, my graph time intervals not showing again. This is making it difficult challenging my ISP when there's down time from their end. Below are the images.
Any help?
Thanks

I think (not sure) last time someone had that problem, purging and reinstalling the web frontend package solved that.

Please, can you assist me doing purging and reinstalling? I'm using Ubuntu Server 24.04 with PHP 8.3

[Markku]

Take backups
sudo apt purge zabbix-frontend-php
sudo apt install zabbix-frontend-php

Hello, I have upgraded recently from 5.4 to 7.0.2. Everything is working fine, however I have the same issue as snetgh. The X axis shows only dots, but not time values. I have tried reinstalling the front end but the issue still persists. I use also Ubuntu Server 24.04 with PHP 8.3.

[snetgh]

I think the issue is with the PHP 8.3. I tried the installation on Ubuntu 24.04 with PHP 8.2 and it works fine. If the Zabbix Team can look into the issue with PHP 8.3

I've got the same issue after upgrading from 22.04 to 24.04.01 just yesterday.
/usr/share/zabbix/assets/fonts/graphfont.ttf is symlinked properly. zabbix-frontend-php and zabbix-nginx-conf purged, reinstalled.
Logs do not point to any errors, issues.
Very puzzled by why time values are not displayed properly - and this is only on classic graphs.

Edit/update, I tried switching over to PHP 8.2 (from 8.3), purging zabbix-frontend-php and zabbix-nginx-conf, reinstalled, but it didn't help.

Hi Snetgh, I just tried what you suggested, but unfortunately still don't have the timeline values in graphs. Here is what I did:

- I completely removed PHP: sudo apt remove --purge php*
- I reinstalled PHP8.2: sudi apt install php8.2
- Then I reinstalled all required PHP extensions for Zabbix, in version 8.2
- Then I reinstalled Zabbix front-end (notice that it installs several PHP 8.3 extensions!)
- Then changed php.ini values to fit the required for zabbix front-end to work properly
- Finally restarted apache service

After all this, if I check my computer it says I am on PHP 8.2:

root@ticsvzabbix:~# php -v
PHP 8.2.23 (cli) (built: Aug 30 2024 09:22:17) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.23, Copyright (c) Zend Technologies
with Zend OPcache v8.2.23, Copyright (c), by Zend Technologies

Then, when accessing the front-end for the first time, I get the welcome config screen. After going thru it, I access my dashboard. If I check on any graph I can see issues with the timeline as I had before:



Am I missing something?

Thanks,
Jordi

Just checking in to see if anyone has been able to resolve this.

Hi everyone, I have the same problem too:



Configuration: Ubuntu Server 24.04, php8.3-fpm, Apache2
I've tried everything, but the result remains the same.
...just waiting

Same problem:

Zabbix Server 7.0.6

Ubuntu 24.04, Apache2, PHP 8.3 via Apache (not fpm)

I had the same problem after upgrading to Ubuntu 24.04 base image. Check that you are not using the repository:

ppa:ondrej/php 

When I built the image, it was specified in the Dockerfile. After removing it, everything worked as it should. Along the way, I updated php to version 8.3. Image based on Ubuntu 24.04. Zabbix version 6.4.20.

[itechniker]

Thank you for the solution. I used this repository since years for PHP-packages, because it's a bit more up2date I thought. But it looks like there are also bugs in it.

[softa]

So, i removed the

ppa:ondrey/php 

and then install deb package of php8.3, but the problem was not resolved

[softa]

I found a solution:
1. Remove ppa:ondrey/php
2. However, after switching to the stock distro version of

libgd3

the problem disappeared.

[troffasky]

This is not just an Ubuntu issue, I am having the same issue on Debian with PHP 8.2 and libgd3 2.3.3-12+b1. So I guess the issue lies with libgd3.
Or not. Actual issue is here:
