 class Ingester(utsdb.Ingester):
     """Same as universal_tsdb.Ingester but sets measurement_prefix.
-    so measurement becomes measurement_prefix.measurement"""
+
+    Handy with ``@tsdb_append_metric_for_class_setter_or_getter`` decorator
+    to be used in hardware controlled classes
+
+    Parameters
+    ----------
+    measurement_prefix: str (default is empty)
+        standard ``utsdb`` measurement becomes measurement_prefix.measurement
