NVME-SMART-LOG(1) NVMe Manual NVME-SMART-LOG(1) NAME nvme-smart-log - Send NVMe SMART log page request, returns result and log SYNOPSIS nvme smart-log <device> [--namespace-id=<nsid> | -n <nsid>] [--raw-binary | -b] [--output-format=<fmt> | -o <fmt>] [--verbose | -v] DESCRIPTION Retrieves the NVMe SMART 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 smart 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 -n <nsid>, --namespace-id=<nsid> Retrieve the SMART log for the given nsid. This is optional and its success may depend on the device's capabilities to provide this log on a per-namespace basis (see the NVMe Identify Controller for this capability). The default nsid to use is 0xffffffff for the device global SMART log. -b, --raw-binary Print the raw SMART log buffer to stdout. -o <fmt>, --output-format=<fmt> Set the reporting format to normal, json or binary. Only one output format can be used at a time. -v, --verbose Increase the information detail in the output. EXAMPLES • Print the SMART log page in a human readable format: # nvme smart-log /dev/nvme0 • Print the raw SMART log to a file: # nvme smart-log /dev/nvme0 --raw-binary > smart_log.raw It is probably a bad idea to not redirect stdout when using this mode. NVME Part of the nvme-user suite NVMe 10/31/2024 NVME-SMART-LOG(1)
