Hi Kevin E. Eckart,
Thanks for reaching out to Microsoft Q&A.
No, Azure Managed Grafana instances cannot be restarted manually. Unlike a self-hosted Grafana setup, Azure Managed Grafana is a managed service, meaning MS handles maintenance, scaling, and updates, including restarts.
If UI is not coming up after attempting to add a 3rd party plugin, here are some potential next steps that you could try:
Undo the Plugin Installation: You can try reverting the plugin installation if you still have access to the instance via the Azure portal or API. Look for options to disable or remove the plugin.
Check Logs: If you can access the logs for the Grafana instance, examine them for errors related to the plugin. Logs might provide clues on what went wrong.
If the UI remains unresponsive, your best option may be to contact Azure support. They can investigate the issue further and may be able to perform a managed restart or rollback the configuration.
For future plugin installations, it's a good idea to verify compatibility with Azure Managed Grafana, as not all third-party plugins are supported in the managed environment.
