 ### Injector telemetry

-- `vault_agent_injector_request_queue_length` - A gauge of webhook requests in

+Vault Agent injector collects the following Prometheus metrics in addition to
+the default set of `golang` metrics:
+
+- `vault_agent_injector_request_queue_length` - The number of pending webhook requests for the injector.
 
 - `vault_agent_injector_request_processing_duration_ms` - A histogram of webhook
   request processing times in milliseconds.
 
 - `vault_agent_injector_injections_by_namespace_total` - The total count of
-  Agent container injections by Kubernetes `namespace` and `injection_type`,
-  where `injection_type` is `init_only`, `sidecar_only`, or `init_and_sidecar`.
+  Agent container injections, grouped by Kubernetes `namespace` and `injection_type`.
+  Vault Agent counts the following injection types:
+    - `init_only`
+    - `sidecar_only`
+    - `init_and_sidecar`.
 
 - `vault_agent_injector_failed_injections_by_namespace_total` - The total count
-  of failed Agent Sidecar injections by Kubernetes `namespace`.
+  of failed Agent Sidecar injections, grouped by Kubernetes `namespace`.
 
-Enable metrics collection in the injector by setting [`injector.metrics.enabled:
-true`](/vault/docs/platform/k8s/helm/configuration#metrics) in the Helm chart.
