500 Internal Server Error zabbix plugin

Hello,

How do you downgrade a plugin in Grafana Docker Compose?

I'm getting the 500 Internal Server Error zabbix plugin today. No updates have been done which is odd. It only seems to be on heavy dashboards.

Zabbix Plugin Version - 6.3.2
Grafana - 13.0.1 (Docker Compose)
Zabbix - 7.4.10 with Nginx as the front end (Ubuntu OS)

My Nginx PHP settings are these defaults:

/etc/php/8.3/fpm/pool.d/zabbix-php-fpm.conf

php_value[max_execution_time] = 300
php_value[memory_limit] = 128M
php_value[post_max_size] = 16M
php_value[upload_max_filesize] = 2M
php_value[max_input_time] = 300
php_value[max_input_vars] = 10000

I did change php_value[memory_limit] = 128M to 1024M which didn't help.

I see this log:

2026/05/18 11:05:02 [error] 13617#13617: *46 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Allowed memory size of 1073741824 bytes exhausted (tried to allocate 12582912 bytes) in /usr/share/zabbix/ui/include/classes/core/CJsonRpc.php on line 107" while reading response header from upstream, client: 10.111.105.60, server: zabbix-outdoor.domain.com, request: "POST /api_jsonrpc.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/zabbix.sock:", host: "zabbix-ouor.domain.com"

In my config.env I have

GF_PLUGINS_PREINSTALL=alexanderzobnin-zabbix-app

I did try

GF_PLUGINS_PREINSTALL=alexanderzobnin-zabbix-app:6.3.0 

Restarted docker compose and it remains on 6.3.2.

Any ideas?

Help with getting certain information into alert

Hello,

I've got a nice Teams alert working with lots of information sent within the alert. However I just can't get the firmware version to show in the alert.

Here is what I have.

NVMe Device: {#NVME_DEVICE}

I'm using a discovery like this which works:

Trigger works:

Latest data is good:

The is what my Teams alert shows:

With

NVMe Device: {#NVME_DEVICE}
NVMe Status: {ITEM.VALUE1}
{EVENT.OPDATA}

Should I be using {ITEM.VALUE1}?

Is there a way to test these alert and not have to wait until the issue happens?

Thanks

Hello,

v13 question.

I've upgraded from 12.3 to 13.0.1 and I've gone to a panel in edit mode and selected copy and then I've gone to another Grafana page to paste it, but there doesn't seem to be an option to paste any more, has it moved?

Or maybe I'm losing the plot :D

Hello,

From time to time we get flapping ports on some Cisco switches, we only see this in the switch logs. We have nearly 200 Cisco switches and what I currently do to graph and detect this is send all switch logs to Grafana Loki and I graph it based on when the work "flapping" is detected, it works well to be honest.

All switches are in Zabbix and being monitored using the Cisco IOS template which won't be able to detect this. Is there any sort or what Zabbix can detect Spanning Tree changes or flapping ports?

Thanks

Hello,

This device has been triggering alerts all day when it hits 100%, my trigger it so monitor for 90mins if the average is over 90% for that time. It works fine, but how can I graph this to show when a trigger started (problem) and when it ended (resolved)?

In Grafana it does this, I'm sure I've see something similar in Zabbix. I'm on v7.4.9

Thanks
