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'.
