Any update here?

[gustavogurg]

Having the same issue. Did any of you guys manage to fix it somehow?

We've also started seeing this issue out of the blue.

Grafana 10.3.3, 10.4.2
Plugin: 4.4.8
Grafana OS: RHEL 8.9
Zabbix Servers: 6.4.10, 6.4.13, 7.0.0beta2

Plugin installed/updated via the CLI. We've got 3 separate Zabbix datasources running different Zabbix versions as noted above and they're all affected. Reinstalling the plugin had no effect.

Only error in /var/log/grafana/grafana.log:

logger=context userId=22 orgId=1 uname="redacted" t=2024-04-24T13:13:13.937151263-07:00 level=error msg="Internal server error" error="[plugin.downstreamError] client: failed to call resources: [plugin.unavailable] plugin unavailable" remote_addr=...** traceID=

I have not been able to fix this, unfortunately.
I may start looking at pulling a copy of this plugin and trying to dedicate some time looking at fixing this.
If anyone else is interested hmu

[gustavogurg]

Im very insterested as the issue persists here. Please if you find any way around it let us know.

I found another post on here reporting the same error and a user provided this response:

i've found the solution, and the cause.
on my side it was because the system is hardened and the mount option on /var/lib was set to noexec.
if you got this error try to change the Plugin path of grafana, i set mine on /srv/ and it work perfectly

I can confirm that was my issue as well. After moving the plugins to /opt/grafana in my case, all was well.

[NotTheRealAdam]

My instance is windows but ill take a look!

[NotTheRealAdam]

Well, I took a look and for my Windows Instance this doesnt help!

[NotTheRealAdam]

I am gonna drop all my troubleshooting here as I try to figure out the issue -
All a personal lab enviroment.

Spent a good 1 hour on this and couldnt get it fixed 👎

[NotTheRealAdam]

Anyone have any luck with the Windows version of this?

[NotTheRealAdam]

I guess this one is going to die out?

[jadezi]

Have you tried adding the directory of the plugin to the system environment variable？

[NotTheRealAdam]

Have you tried adding the directory of the plugin to the system environment variable？

I have but are you able to provide this for a windows installation in case I have done something wrong.

[jadezi]

I just tried and it has been successful.
You need to add the plugin directory to the system variable PATH

[NotTheRealAdam]

Ah, I was looking within Grafana itself :|

[NotTheRealAdam]

Ill give this a try and come back to you.

[NotTheRealAdam]

I can confirm, tha got that work.
Very odd that was the fix.
@jadezi answer is correct. I shall close this with this comment now.

Thank you to the community for assisting with this.

[mnzarthur]

can you help me?

I followed the procedure of adding the file path of the plugin folder to the SYSTEM VARIABLE (PATH) on my Windows machine where Grafana is running, and then restarted the services. However, it still didn't work. I have tried various procedures without success. I'm using the appliance on Hyper-V, and Grafana is running directly on Windows 10. The network communication between both works normally.
