ndctl-monitor - Monitor the smart events of nvdimm objects
ndctl monitor [<options>]
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 configuration file at /etc/ndctl/monitor.conf
Both, the values in configuration file and in options will work. If there is a conflict, the values in options will override the values in the configuration file. Any updated values in the configuration file will take effect only after the monitor process is restarted.
Run a monitor as a daemon to monitor DIMMs on bus “nfit_test.1”
ndctl monitor --bus=nfit_test.1 --daemon
Run a monitor as a one-shot command and output the notifications to /var/log/ndctl.log
ndctl monitor --log=/var/log/ndctl.log
Run a monitor daemon as a system service
systemctl start ndctl-monitor.service
-b; --bus=
Enforce that the operation only be carried on devices that are attached
to the given bus. Where bus can be a provider name or a bus id number.
-d; --dimm=
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.
-l; --log=
Send log messages to the specified destination.
“<file>”: Send log messages to specified <file>. When fopen() is not able to open <file>, log messages will be forwarded to syslog.
“syslog”: Send messages to syslog.
“standard”: Send messages to standard output.
The default log destination is syslog if “–daemon” is specified, otherwise standard. Note that standard and relative path for `<file> will not work if “–daemon” is specified.
-c; --config-file=
Provide the config file to use. This overrides the default config
typically found in /etc/ndctl
--daemon
Run a monitor as a daemon.
-D; --dimm-event=
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.
The monitor will attempt to enable the alarm control bits for all specified events.
-u; --human
Output monitor notification as human friendly json format instead of the
default machine friendly json format.
-v; --verbose
Emit extra debug messages to log.
