+Monitoring Drive Writes Per Day
+-------------------------------
+
+Drives can be monitored for the level of write intensity of the
+workload, and alerts defined for drives that are persistently
+exceeding their stated level of write endurance.  To enable this
+feature, set the flag ``create_dwpd_ratings``:
+
+.. code-block:: console
+
+    (kayobe) [stack@node ~]$ cd etc/kayobe
+    (kayobe) [stack@node kayobe]$ kayobe playbook run ansible/deployment/smartmon-tools.yml -e create_dwpd_ratings=true
+
+This flag scans for NVME/SSD devices in the system and creates a new
+file, ``dwpd-ratings.yml``, in the directory of the current environment.
+
+.. note::
+   The playbook assigns placeholder values for write endurance for each
+   drive model. These values should be updated with specifications from
+   vendor datasheets.
