## SYNOPSIS

```
nvme [<global-options>] solidigm workload-tracker <device>
                        [--uuid-index=<id> | -U <id>]
                        [--enable | -e]
                        [--disable | -d]
                        [--sample-time=<time> | -s <time>]
                        [--type=<type> | -t <type>]
                        [--run-time=<seconds> | -r <seconds>]
                        [--flush-freq=<count> | -f <count>]

                        [--trigger-on-latency | -L]
```

## DESCRIPTION

Captures and displays real-time workload tracker samples for the given Solidigm NVMe device. This command allows for monitoring and analysis of the device’s workload characteristics.

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

## OPTIONS

- \-U \<id\>, --uuid-index=\<id\>

  Specify the UUID index (0-127) for the command.

- \-e, --enable

  Enable the workload tracker before capturing samples.

- \-d, --disable

  Disable the workload tracker after capturing samples.

- \-s \<time\>, --sample-time=\<time\>

  Set the sample interval. Valid values are: default, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1s, 5s, 10s, 30s, 1m, 5m, 10m, 30m, 1h.

- \-t \<type\>, --type=\<type\>

  Set the tracker type. Valid types are: Base, CmdQ, Pattern, RandSeq, Throttle, Power, Defrag.

- \-r \<seconds\>, --run-time=\<seconds\>

  Limit runtime capture time in seconds.

- \-f \<count\>, --flush-freq=\<count\>

  Number of samples (1 to 126) to wait before extracting data. Default is 100 samples.

- \-w, --wall-clock

  Log current wall timestamp when entry was retrieved.

- \-T \<field\>, --trigger-field=\<field\>

  Field name to stop trigger on.

- \-V \<value\>, --trigger-threshold=\<value\>

  Field value to trigger stop sampling.

- \-D, --trigger-on-delta

  Trigger on delta to stop sampling.

- \-L, --trigger-on-latency

  Use latency tracker to trigger stop sampling.

- \-v, --verbose

  Increase logging verbosity. Can be used multiple times.

## 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. Other versions are rejected.

- \--quiet

  Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

- \--set-options=\<key=value\>\[,\<key=value\>...\]

  Set libnvme library options for this invocation. Supported keys are *force-4k*, *mi-probe-enabled*, *test-base-dir* and *test-sysfs-dir*.

- \--timeout=\<ms\>

  Set the timeout for the command in milliseconds. *infinite* or *-1* waits without a time limit (0xffffffff).

- \-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)](/nvme-cli.conf/5.md). A command-line flag always overrides the file.

## EXAMPLES

• Enable the workload tracker and capture samples:

```
# nvme solidigm workload-tracker /dev/nvme0 --enable
```

• Capture workload tracker samples with a 1ms interval for 60 seconds:

```
# nvme solidigm workload-tracker /dev/nvme0 --enable --sample-time=1ms --run-time=60
```

• Disable the workload tracker:

```
# nvme solidigm workload-tracker /dev/nvme0 --disable
```

• Enable the workload tracker and capture samples with a specific sample time and type:

```
# nvme solidigm workload-tracker /dev/nvme0 --enable --sample-time=1ms --type=Base
```

• Capture Power tracker samples with a 10-second interval for 5 minutes:

```
# nvme solidigm workload-tracker /dev/nvme0 --enable --type=Power --sample-time=10s --run-time=300
```
