Upgrading kube-prometheus-stack chart causing Metrics section disappearance

Monitoring and Observability Grafana
1

Hello, I’ve just upgraded from kube-prometheus-stack 69.4.1 to 75.3.6. This bumps the grafana helm chart from 8.9.1 (image 11.5.1) to 9.2.7 (image 12.0.2)
I’ve noticed that the “Metrics” section within Drilldown has disappeared. Does this sound familiar to anyone?

I would recommend checking you Plugins under “Home > Admin > Plugins and data > Plugins”; I’ve sometimes seen plugins fail signature validation or other things and thus disappear from the Drilldown view. You can also shell into your grafana instance and run grafana cli plugins list and whatnot to inspect/troubleshoot

Thanks , I appreciate the response! I tried grafana cli plugins ls however this seems to only report non-core plugins

   grafana cli plugins [command options]

COMMANDS:
   ...
   ls                       list installed plugins (excludes core plugins)```


I believe the metrics drilldown is a built-in plugin that should "come for free" with all grafana installs per <https://grafana.com/docs/grafana/latest/explore/simplified-exploration/metrics/get-started/#before-you-begin>
>  The Grafana Metrics Drilldown app is installed in both Grafana Cloud and self-managed Grafana by default.

I went ahead and check my upgraded instance as well as my previous instance (which does show “Metrics” under the “Explore” tab), and they have the same set of plugins under “Home > Admin > Plugins and data > Plugins”
