+
+### Configuration:
+
+```toml
+# Get metrics from Kubernetes services    
+  [[inputs.kubernetes.apiserver]]
+    url = "http://mtl-nvcbladea-15.nuance.com:8080"
+    endpoint = "/metrics"
+    timeout = 5.0
+    # includes only metrics which match one of the
+    # following regexp
+    includes = ["apiserver_.*"]
+
+  [[inputs.kubernetes.scheduler]]
+    url = "http://mtl-nvcbladea-15.nuance.com:10251"
+    endpoint = "/metrics"
+    timeout = 1.0
+    # DO NOT include metrics which match one of the
+    # following regexp
+    excludes = ["scheduler_.*"]
+
+  [[inputs.kubernetes.controllermanager]]
+    url = "http://mtl-nvcbladea-15.nuance.com:10252"
+
+  [[inputs.kubernetes.kubelet]]
+    url = "http://mtl-nvcbladea-15.nuance.com:4194"
+    # You should increase metric_buffer_limit
+    # Because of number of kubelet metrics
+    # otherwise you can limit metrics with
+    # the following 'excludes' argument
+    excludes = ["container_.*"]
