+title: Kubernetes Explorer
+description: Browse Kubernetes clusters read-only in Infra > Kubernetes 2, with resource lists, a honeycomb cluster map, and per-object details.
+---
+
+**Infra › Kubernetes 2** is a read-only browser for the Kubernetes telemetry you already send to OpenObserve. It sits next to the existing **Kubernetes** page, which is unchanged.
+
+It reads three sources through the normal PromQL and SQL search APIs, so there is nothing extra to set up:
+
+- **kube-state-metrics** for the object inventory: pods, nodes, workloads, PVCs, HPAs, and namespaces.
+- **kubelet stats** for CPU, memory, network, and filesystem usage.
+- The **`k8s_events`** stream for events.
+
+If none of these are present, the page shows **No Kubernetes telemetry visible to you yet**.
+

+
+## Views
+
+Use the rail on the left to switch views, and the header to pick a cluster and time range:
+
+- **Cluster**: **Overview** and **Map**
+- **Nodes**
+- **Workloads**: **Overview**, **Pods**, **Deployments**, **DaemonSets**, **StatefulSets**, **ReplicaSets**, **Jobs**, **CronJobs**
+- **Storage**: PersistentVolumeClaims
+- **Autoscaling**: HorizontalPodAutoscalers
+- **Namespaces** and **Events**
+
+Each resource view is a sortable, searchable list with columns for that kind. Filter by namespace from the header, and click a row to open its details.
+
+## Cluster map
+
+The **Map** view shows pods or nodes as a honeycomb:
+
+- **Fill by**: CPU or memory as a percentage of request, limit, or allocatable, restarts, or status.
+- **Group by**: node, namespace, workload, none, or any label observed on your pods or nodes.
+- **Filter**: narrow the map with `key: value` label terms.
+
+Hover a cell for a tooltip and click it to open its details. Click **Show as list** to see the same selection as a list.
+
+![TODO: screenshot of the cluster map grouped by namespace and filled by CPU](images/placeholder.png)
+
+## Details panel
+
+Clicking any object opens a details panel beside the list or map, so you can keep browsing while it is open. It shows:
+
+- Metric charts for the selected time range.
+- Metadata, such as namespace, labels, annotations, and the owning object.
+- Sections specific to the kind, such as pod containers and conditions, or node capacity.
+- The object's events.
+
+For a pod, click **View logs** to open Logs for that pod's log stream over the current time range.
+
+## Share a view
+
+Every view, filter, sort, and open panel is kept in the URL, so you can bookmark or share exactly what you see.
