# [DESCRIPTION](#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 &lt;device&gt; parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

# [OPTIONS](#OPTIONS)

-U &lt;id&gt;, --uuid-index=&lt;id&gt;

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 &lt;time&gt;, --sample-time=&lt;time&gt;

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

-t &lt;type&gt;, --type=&lt;type&gt;

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

-r &lt;seconds&gt;, --run-time=&lt;seconds&gt;

Limit runtime capture time in seconds.

-f &lt;count&gt;, --flush-freq=&lt;count&gt;

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 &lt;field&gt;, --trigger-field=&lt;field&gt;

Field name to stop trigger on.

-V &lt;value&gt;, --trigger-threshold=&lt;value&gt;

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](#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 &lt;fmt&gt;, --output-format=&lt;fmt&gt;

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

--output-format-version=&lt;version&gt;

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=&lt;key=value&gt;\[,&lt;key=value&gt;...]

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

--timeout=&lt;ms&gt;

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

# [EXAMPLES](#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
```
