-    Use a list of custom attributes to annotate the data from this agent instance. Separate keys and values with colons `:`, as in `KEY: VALUE`, and separate each key-value pair with a line break. Keys can be any valid YAML except slashes `/`. Values can be any YAML string, including spaces.
+    Use a list of custom attributes to annotate the data from this agent instance. Separate keys and values with colons `:`, as in `KEY: VALUE`, and separate each key-value pair with a line break. Keys can be any valid YAML except slashes `/`. Values can be any YAML string, including spaces. Starting the key with `label.` will make sure it remains as is, even if that host might run in different cloud environments, where the cloud tags or cloud labels might interact with it in the combined decoration of tags. In contrast, `custom_labels` might be prefixed with `gcp.` or `azure.` when running in those environments and when combining data from the infrastructure agent with cloud monitoring together.
 
     Example as a YAML attribute:
 
     ```yml
     custom_attributes:
-      environment: production
-      service: login service
-      team: alpha-team
+      label.environment: production
+      label.service: login service
+      label.team: alpha-team
     ```
 
     Example as an environment variable:
 
     ```ini
-    NRIA_CUSTOM_ATTRIBUTES='{"customAttribute_1":"SOME_ATTRIBUTE","customAttribute_2": "SOME_ATTRIBUTE_2"}'
+    NRIA_CUSTOM_ATTRIBUTES='{"label.customAttribute_1":"SOME_ATTRIBUTE","label.customAttribute_2": "SOME_ATTRIBUTE_2"}'
     ```
 
     NRQL example filtering by custom attribute:
 
     ```sql
-    FROM SystemSample SELECT * WHERE environment = 'production'
+    FROM SystemSample SELECT * WHERE label.environment = 'production'
     ```
