# nvme-endurance-log(1) Manual Page

## NAME

nvme-endurance-log - Send NVMe Endurance log page request, returns result and log

## SYNOPSIS

    nvme endurance-log <device> [--group-id=<group> | -g <group>]
                            [--output-format=<fmt> | -o <fmt>]

## DESCRIPTION

Retrieves the NVMe Endurance 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 endurance 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, the raw buffer may be printed to stdout for another program to parse, or reported in json format.

## OPTIONS

-g <group>
--group-id=<group>

  The endurance group identifier.

-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

- Print the Endurance log page in a human readable format:

      # nvme endurance-log /dev/nvme0

- Print the raw Endurance log to a file:

      # nvme endurance-log /dev/nvme0 --output=binary > endurance_log.raw

  It is probably a bad idea to not redirect stdout when using this mode.
