Suggestions, please!

It is really hard to suggest something here as it doesn't have a clear reproduction steps and the error you pasted is pretty generic. Can you help us with clear reproduction steps so we can help?

Could it potentially be related to this? https://github.com/grafana/grafana-zabbix/issues/1622

The plugin holds correctly the 1 hour interval but more than that the plugin process starts to restart.

I am still checking. Thanks for the response. Let me come back with an update.

Error 500 may indicate that Zabbix is having difficulty processing the complexity of your API request. To resolve this, consider optimizing your Zabbix web server (nginx or Apache), or alternatively, try reducing the scope of your query in Grafana. These performance adjustments may be necessary to ensure that Zabbix can handle processing demands efficiently.

I am experiencing this with Juniper routers only, while other SNMP-monitored devices are working fine. I tried minimizing the scope of the query, but the issue persists. I have Nginx as the Zabbix web server. could you please suggest what kind of optimization would help here? Thanks

[bernardolankheet]

Can you show a query on your dashboard?

you can change php timeouts and requests normally in:

/etc/php-fpm.d/www.conf [On CentOS/RHEL/Fedora]
/etc/php/7.2/fpm/pool.d/www.conf [On Ubuntu/Debian/Mint]
/etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf [On Redhat]

In nginx, normally in .conf file, custom body size, buffer, timeout and etc.

There is no way to suggest a pattern without knowing your environment, but these configurations are normally carried out in large environments, with several simultaneous accesses to Grafana and the Zabbix frontend.

I also encounter the same error. Initially I tried to upgrade from 9.4.12 to 10.4.1 but ran into issues. For testing, I installed version 10.4.1 in a new environment with plugin 4.4.6, but the problem persists. Grafana is installed on a Windows server. It is important to note that the plugin was working correctly before the upgrade. logger=context userId=1 orgId=1 uname=admin t=2024-04-05T17:38:42.1804241+02:00 level=error msg="Internal server error" error="[plugin.downstreamError] client: failed to call resources: [plugin.unavailable] plugin unavailable" remote_addr=[::1] traceID= logger=context userId=1 orgId=1 uname=admin t=2024-04-05T17:38:42.1804241+02:00 level=error msg="Request Completed" method=POST path=/api/datasources/1/resources/zabbix-api status=500 remote_addr=[::1] time_ms=1 duration=1.8828ms size=116 referer=http://localhost:3000/connections/datasources/edit/ddhtst12pq8sge handler=/api/datasources/:id/resources/* status_source=downstream
