+= Changing CVO log level
+
+The Cluster Version Operator (CVO) log level verbosity can be changed by the cluster administrator. There are four log levels.
+
+* `Normal` - The default log level. Contains working log information when everything is fine. Provides helpful notices for auditing or common operations.
+* `Debug` - Used when something goes wrong. Expect a higher quantity of notices.
+* `Trace` - Increases the verbosity of the logs. Used to diagnose errors.
+// rephrase traceall
+* `TraceAll` - Used when something is broken at the level of API content/decoding. It will dump complete body content.  If turned on in a production cluster prepare for widespread performance issues and very large log files.
+
+.Prerequisites
+* You have access to the cluster as a user with the `cluster-admin` role.
+* You have installed the {oc-first}.
+
+.Procedure
