+NAME
+----
+ndctl-monitor - Monitor the smart events of nvdimm objects
+
+SYNOPSIS
+--------
+[verse]
+'ndctl monitor' [<options>]
+
+DESCRIPTION
+-----------
+Ndctl monitor is used for monitoring the smart events of nvdimm
+objects and dumping the json format notifications to syslog, standard
+output or a logfile.
+
+The objects to monitor and smart events to notify can be selected by
+setting options and/or the default configuration file
+(/etc/ndctl/monitor.conf). Both of the values in configuration file
+and in options will work. If there is a conflict, the values in
+options will override the values in configuration file. The changed
+values in configuration file will work after the monitor is restarted.
+
+The smart threshold evnet alarm of dimm will be turned on when the
+monitor gets started, if it is set off.
+
+EXAMPLES
+--------
+
+Run a monitor as a daemon to monitor DIMMs on bus "nfit_test.1"
+[verse]
+ndctl monitor --bus nfit_test.1 --daemon
+
+Run a monitor as a one-shot command and output the notifications to
+/var/log/ndctl.log
+[verse]
+ndctl monitor -log /var/log/ndctl.log
+
+Run a monitor daemon as a system service
+[verse]
+systemctl start ndctl-monitor.service

+	A 'nmemX' device name, or dimm id number. Select the devices to
+	monitor reference the given dimm.
+
+-r::
+--region=::
+	A 'regionX' device name, or a region id number. The keyword 'all'
+	can be specified to carry out the operation on every region in
+	the system, optionally filtered by bus id (see --bus= option).
+
+-n::
+--namespace=::
+	A 'namespaceX.Y' device name, or namespace region plus id tuple
+	'X.Y'.

+
+--daemon::
+	Run a monitor as a daemon.

+	Name of an smart health event from the following:
+	- "dimm-spares-remaining": Spare Blocks Remaining value has gone
+	   below the pre-programmed threshold.
+	- "dimm-media-temperature": NVDIMM Media temperature value has
+	   gone above the pre-programmed threshold.
+	- "dimm-controller-temperature": NVDIMM Controller temperature
+	   value has gone above the pre-programmed threshold.
+	- "dimm-health-state": NVDIMM Normal Health Status has changed
+	- "dimm-unclean-shutdown": NVDIMM Last Shutdown Status was a
+	   unclean shutdown.
