I am using Linux Ubuntu 18.04, Grafana version 8.0.3.
I am using Grafana for last few months. Initially using worldmap panel, later
panodata map panel. Both were working fine. Suddenly the map-panels are not working.
It is not appearing on the panel and when I try to check by clicking the ‘edit’ on the panel, it shows ‘unexpected error’. I have seen the grafana log (attached). Seems the ‘plugin is not found’. Should I have to reinstall the plugin? world-map plugin I installed from grafana plugin store and panodata manually downloading the zip file.
I am using ‘panodata-map-panel’ and it is placed under /var/lib/grafana/plugins/.
I have edited the ‘/etc/grafana/grafana.ini’ file as instructed.
allow_loading_unsigned_plugins = “panodata-map-panel”
Actually the previous map panel (grafana-worldmap-panel) that is also not working. When I use either of them in a panel, nothing appears. Clicking the ‘edit’ from the menu gives ‘unexpected error’ msg.
I was using these map panels from July onward and till last week there was no problem. Seems suddenly it cannot find these plugins.
Adding a few more things, if it helps you to identify the problem.
While checking the list of plugins from Dashboard → Configuration, it does not show the ‘worldmap’ or ‘panodata’ along with some other. But they are visible while selecting for an opening panel ‘click to change visualization’.
From Plugins/Plugin Admin → Readme
The grafana catalog is enabled or disabled by setting plugin_admin_enabled in the setup files.
No, I haven’t. I have started using Grafana relatively recently. Around July this year. Haven’t updated after that. Haven’t changed in grafana setting or related files/directories.
Just now one thing came to my mind. I was trying to install Node-RED and had some trouble installing it. Tried various things as suggested in different net-forum. So it strikes me if that could cause the problem. So I stopped the current docker-image and used a previous image and everything is fine. Also, when I list up all the plugins from Configuration → Plugins, it shows all the plugins as it should.
So it seems I had messed up something while trying to install and changing setup etc. I need to dug deep to find what was that.
Sorry for the troubles and thank you for trying to help me out. There is nothing wrong with the grafana. As I did not directly touch grafana related setup I thought something went wrong with grafana. It was my fault. Somewhere the permission mode probably has changed, causing some plugin-files not-found.
ps. In the grafana error log, there was
open /var/lib/grafana/plugins/partials/module.html: no such file or directory”
and the ‘partials’ directory itself was gone. After changing back to the older docker, ‘partials/module.html’ exists as it should. Somehow file/directory structure under /var/lib/grafana/plugins/ had changed, causing all the troubles.
