Hi, The warning and danger indicator in the capacity chart points to the nearful and full ratio set to the cluster and the default values for them are 85% and 95% respectively. You can do a `ceph osd dump | grep ratio` and see those. When this got introduced, there was a blog post <https://ceph.io/en/news/blog/2023/landing-page/#capacity-card>explaining how this is mapped in the chart. But when your used storage crosses that 85% mark, the chart is colored with yellow to indicate the user, and when it crosses 95% (or the full ratio) the chart is colored with red to tell that. But that doesn't mean the cluster is in bad shape but its a visual indicator to tell you you are running out of storage. Regarding the Cluster Utilization chart, it gets metrics directly from prometheus so that it can be used to show a time-series data in UI rather than the metrics at current point in time (which was used before). So if you have prometheus configured in dashboard and its url is provided in the dashboard settings `ceph dashboard set-prometheus-api-host <url-of-prometheus>` then you should be able to see the metrics. In case you need to read more about the new page you can check here <https://docs.ceph.com/en/latest/mgr/dashboard/#overview-of-the-dashboard-landing-page> .
