SYNOPSIS

nvme [<global-options>] ocp get-telemetry-profile <device>
                        [--sel=<select> | -s <select>]
                        [--namespace-id <nsid> | -n <nsid>]
                        [--no-uuid | -u]

DESCRIPTION

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

This will only work on OCP compliant devices supporting this feature. Results for any other device are undefined.

On success it returns 0, error code otherwise.

OPTIONS

-n <nsid>
--namespace-id=<nsid>

NSID: Assign the different kind of nsid value(like active, inactive and invalid nsids) and check the get feature command response:

-s <select>
--sel=<select>

Select (SEL): This field specifies which value of the attributes to return in the provided data:

GLOBAL OPTIONS

The following options are defined at the top-level nvme command and are available to this subcommand:

--dry-run

Print the command that would be executed, but do not actually execute it.

--no-ioctl-probing

Disable probing for 64-bit IOCTL support.

--no-retries

Disable retry logic on transient errors.

-o <fmt>
--output-format=<fmt>

Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time.

--output-format-version=<version>

Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names.

--timeout=<ms>

Set the timeout for the command in milliseconds.

-v
--verbose

Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file.

EXAMPLES

  • Has the program issue a get-telemetry-profile to retrieve the 0xC8 get features. 

    # nvme ocp get-telemetry-profile /dev/nvme0
