+WatchNamespaceSelector is a LabelSelector to find matching namespaces to watch as in WatchNamespaceses.

+Default: -

 ### controlNamespace (string, required) {#loggingspec-controlnamespace}
 
 Namespace for cluster wide configuration resources like ClusterFlow and ClusterOutput. This should be a protected namespace from regular users. Resources like fluentbit and fluentd will run in this namespace as well.
