Is it possible for you to take a screen shot and upload it here? It would be very helpful for debugging.

Hi, I don't think this is caused by the Lustre version change. The plugin piechart-panel of Grafana is not installed some how. I would suggest to:

1. Check whether the plugins are copied to the proper directory properly:
   # ls /var/lib/grafana/plugins/
   Grafana_Status_panel piechart-panel savantly-heatmap-panel

2. If the plugin directorie are not complete, please manually fix it by coping the plugin directory into /var/lib/grafana/plugins. The plugins can be found in the ISO.

3. If the ISO is broken, please rebuild the ISO or download the plugin from https://github.com/grafana/piechart-panel.

4. If the plugin are properly installed in /var/lib/grafana/plugins/, I guess need to restart Grafana to start using it:
   # service grafana-server restart

I exec ls /var/lib/grafana/plugins/ and it shows Grafana_Status_panel piechart-panel savantly-heatmap-panel,all plugins are here,and i run service grafana-server restart,however the grafana didnt change
