+# Monitoring other Kubernetes Namespaces
+This guide will help you monitor applications in other Namespaces. By default the RBAC rules are only enabled for the `Default` and `kube-system` Namespace during Install.
+
+# Setup
+You have to give the list of the Namespaces that you want to be able to monitor.
+This is done in the variable `prometheus.roleSpecificNamespaces`. You usually set this in your `.jsonnet` file when building the manifests.
+
+Example to create the needed `Role` and `Rolebindig` for the Namespace `foo` : 
+```
+local kp = (import 'kube-prometheus/kube-prometheus.libsonnet') + {
+  _config+:: {
+    namespace: 'monitoring',
+
+    prometheus+:: {
+      namespaces: ["default", "kube-system","foo"],
+    },
+  },
+};
+ 
+{ ['00namespace-' + name]: kp.kubePrometheus[name] for name in std.objectFields(kp.kubePrometheus) } +
+{ ['0prometheus-operator-' + name]: kp.prometheusOperator[name] for name in std.objectFields(kp.prometheusOperator) } +
+{ ['node-exporter-' + name]: kp.nodeExporter[name] for name in std.objectFields(kp.nodeExporter) } +
+{ ['kube-state-metrics-' + name]: kp.kubeStateMetrics[name] for name in std.objectFields(kp.kubeStateMetrics) } +
+{ ['alertmanager-' + name]: kp.alertmanager[name] for name in std.objectFields(kp.alertmanager) } +
+{ ['prometheus-' + name]: kp.prometheus[name] for name in std.objectFields(kp.prometheus) } +
+{ ['grafana-' + name]: kp.grafana[name] for name in std.objectFields(kp.grafana) }
+
