+# Custom Resource State Metrics
+
+This section describes how to add metrics based on the state of a custom resource without writing a custom resource 
+registry and running your own build of KSM.
+
+## Configuration
+
+A YAML configuration file described below is required to define your custom resources and the fields to turn into metrics.
+
+Two flags can be used:
+
+ * `--custom-resource-state-config "inline yaml (see example)"` or
+ * `--custom-resource-state-config-file /path/to/config.yaml`
+
+If both flags are provided, the inline configuration will take precedence.
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: kube-state-metrics
+  namespace: kube-system
+spec:
+  template:
+    spec:
+      containers:
+      - name: kube-state-metrics
+        args:
+          - --custom-resource-state-config
+          # in YAML files, | allows a multi-line string to be passed as a flag value
+          # see https://yaml-multiline.info
+          -  |
+              spec:
+                resources:
+                  - groupVersionKind:
+                      group: myteam.io
+                      version: "v1"
+                      kind: Foo
+                    metrics:
+                      - name: active_count
+                        help: "Count of active Foo"
+                        ...
+```
+
+### Examples
+
+The examples in this section will use the following custom resource:
+
+```yaml
+kind: Foo
+apiVersion: myteam.io/vl
+metadata:
+    annotations:
+        bar: baz
+        qux: quxx
+    labels:
+        foo: bar
+    name: foo
+spec:
+    order:
+        - id: 1
+          value: true
+        - id: 3
+          value: false
+    replicas: 1
+status:
+    active:
+        type-a: 1
+        type-b: 3
+    conditions:
+        - name: a
+          value: 45
+        - name: b
+          value: 66
+    sub:
+        type-a:
+            active: 1
+            ready: 2
+        type-b:
+            active: 3
+            ready: 4
+    uptime: 43.21
+```
+
+#### Single Values
+
+The config:
+
+```yaml
+kind: CustomResourceStateMetrics
+spec:
+  resources:
+    - groupVersionKind:
+        group: myteam.io
+        kind: "Foo"
+        version: "v1"
+      metrics:
+        - name: "uptime"
+          help: "Foo uptime"
+          each:
+            path: [status, uptime]
+```
+
+Produces the metric:
+
+```prometheus
+kube_myteam_io_v1_Foo_uptime 43.21
+```
+
+#### Multiple Metrics/Kitchen Sink
+
+```yaml
+kind: CustomResourceStateMetrics
+spec:
+  resources:
+    - groupVersionKind:
+        group: myteam.io
+        kind: "Foo"
+        version: "v1"
+      # labels can be added to all metrics from a resource
+      commonLabels:
+        crd_type: "foo"
+      labelsFromPath:
+        name: [metadata, name]
+      metrics:
+        - name: "ready_count"
+          help: "Number Foo Bars ready"
+          each:
+            # targeting an object or array will produce a metric for each element
+            # labelsFromPath and value are relative to this path
+            path: [status, sub]
+
+            # if path targets an object, the object key will be used as label value
+            labelFromKey: type
+            # label values can be resolved specific to this path 
+            labelsFromPath:
+              active: [active]
+            # The actual field to use as metric value. Should be a number.
+            value: [ready]
+          commonLabels:
+            custom_metric: "yes"
+          labelsFromPath:
+            # whole objects may be copied into labels by prefixing with "*"
+            # *anything will be copied into labels, with the highest sorted * strings first
+            "*": [metadata, labels]
+            "**": [metadata, annotations]
+
+            # or specific fields may be copied. these fields will always override values from *s
+            name: [metadata, name]
+            foo: [metadata, labels, foo]
+```
+
+Produces the following metrics:
+
+```prometheus
+kube_myteam_io_v1_Foo_active_count{active="1",custom_metric="yes",foo="bar",name="foo",bar="baz",qux="quxx",type="type-a"} 1
+kube_myteam_io_v1_Foo_active_count{active="3",custom_metric="yes",foo="bar",name="foo",bar="baz",qux="quxx",type="type-b"} 3
+```
+
+### Naming
+
+The default metric names are prefixed to avoid collisions with other metrics.
+By default, a namespace of `kube` and a subsystem based on your custom resource's group+version+kind is used.
+You can override these with the namespace and subsystem fields.
+
+```yaml
+kind: CustomResourceStateMetrics
+spec:
+  resources:
+    - groupVersionKind: ...
+      namespace: myteam
+      subsystem: foos
+      metrics:
+        - name: uptime
+          ...
+```
+
+Produces:
+```prometheus
+myteam_foos_uptime 43.21
+```
+
+To omit namespace and/or subsystem altogether, set them to `_`.
+
+### Logging
+
+If a metric path is registered but not found on a custom resource, an error will be logged. For some resources,
+this may produce a lot of noise. The error log [verbosity][vlog] for a metric or resource can be set with `errorLogV` on
+the resource or metric:
+
+```yaml
+kind: CustomResourceStateMetrics
+spec:
+  resources:
+    - groupVersionKind: ...
+      errorLogV: 0  # 0 = default for errors
+      metrics:
+        - name: uptime
+          errorLogV: 10  # only log at high verbosity
+```
+
+[vlog]: https://github.com/go-logr/logr#why-v-levels
+
+### Path Syntax
+
+Paths are specified as a list of strings. Each string is a path segment, resolved dynamically against the data of the custom resource.
+If any part of a path is missing, the result is nil.
+
+Examples:
+
+```yaml
+# simple path lookup
+[spec, replicas]                         # spec.replicas == 1
+
+# indexing an array
+[spec, order, "0", value]                # spec.order[0].value = true
+
+# finding an element in a list by key=value  
+[status, conditions, "[name=a]", value]  # status.conditions[0].value = 45
+
+# if the value to be matched is a number or boolean, the value is compared as a number or boolean  
+[status, conditions, "[value=66]", name]  # status.conditions[1].name = "b"
+```
