NAME
----
nvme-error-log - Send NVME Error log page request, return result and log

SYNOPSIS
--------
[verse]
'nvme error-log' <device>  [--log-entries=<entries> | -e <entries>]
			 [--raw-binary | -b]
			 [--output-format=<fmt> | -o <fmt>]

DESCRIPTION
-----------
Retrieves NVMe Error log page from an NVMe device and provides the
returned structure.

The <device> parameter is mandatory and may be either the NVMe character
device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

On success, the returned error log structure may be returned in one of
several ways depending on the option flags; the structure may parsed by
the program and printed in a readable format or the raw buffer may be
printed to stdout for another program to parse.

OPTIONS
-------
-e <entries>::
--log-entries=<entries>::
	Specifies how many log entries the program should request from
	the device. This must be at least one, and shouldn't exceed the
	device's capabilities. Defaults to 64 log entries.

-b::
--raw-binary::
	Print the raw error log buffer to stdout.

-o <format>::
--output-format=<format>::
              Set the reporting format to 'normal', 'json', or
              'binary'. Only one output format can be used at a time.


EXAMPLES
--------
* Get the error log and print it in a human readable format:
+
------------
# nvme error-log /dev/nvme0
------------
+

* Print the raw output to a file:
+
------------
# nvme error-log /dev/nvme0 --raw-binary > error_log.raw
------------
+
It is probably a bad idea to not redirect stdout when using this mode.
