Email regarding what? You say “graphless” - why should it include a graph?
Tell us what you’ve configured and what you’re expecting.
An alert email from Grafana. That would previously have contained graphs but now contains a message saying you need the plugin, this message:
Please point us to the instructions you followed, so we know what you did.
here: Grafana Image Renderer plugin for Grafana | Grafana Labs
Is there any other documentation?
grafana-cli plugins list-remote | grep render produces no
Is that different from previously on your system?
I’ve never had to run that command before. However I would expect, if any plugin existed in the repository with “render” in the name, that this command would show it. And I believe the documentation I have now cited implies the existence of so-named a plugin.
Hard to say until you give us enough information to essentially replicate what
you have done.
grafana-cli plugins install grafana-image-renderer
