+
+    By default, the metrics reported by integrations include tags automatically detected from the environment. For example, the metrics reported by a Redis check that runs inside a container include tags associated with the container, such as `image_name`. You can turn this behavior off by setting the `ignore_autodiscovery_tags` parameter to `true`.
+
+1. **Set tag cardinality per integration check**
+
+    You can define the level of tag cardinality (low, orchestrator, or high) on a per-check basis using the `check_tag_cardinality` parameter. This overrides the global tag cardinality setting defined in the Agent configuration.
+
 ```yaml
 init_config:
-
+# Ignores tags coming from autodiscovery
 ignore_autodiscovery_tags: true
 
+# Override global tag cardinality setting
+check_tag_cardinality: low
+
 # Rest of the config here
