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 RoleBinding for the Namespace foo :

local kp = (import 'kube-prometheus/main.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) }
