.SH "DESCRIPTION"
.sp
Captures and displays real\-time workload tracker samples for the given Solidigm NVMe device\&. This command allows for monitoring and analysis of the device\(cqs workload characteristics\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
.SH "OPTIONS"
.PP
\-e, \-\-enable
.RS 4
Enable the workload tracker before capturing samples\&.
.RE
.PP
\-d, \-\-disable
.RS 4
Disable the workload tracker after capturing samples\&.
.RE
.PP
\-s <time>, \-\-sample\-time=<time>
.RS 4
Set the sample interval\&. Valid values are: default, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1s, 5s, 10s, 30s, 1m, 5m, 10m, 30m, 1h\&.
.RE
.PP
\-t <type>, \-\-type=<type>
.RS 4
Set the tracker type\&. Valid types are: Base, CmdQ, Pattern, RandSeq, Throttle, Power, Defrag\&.
.RE
.PP
\-r <seconds>, \-\-run\-time=<seconds>
.RS 4
Limit runtime capture time in seconds\&.
.RE
.PP
\-f <count>, \-\-flush\-freq=<count>
.RS 4
Number of samples (1 to 126) to wait before extracting data\&. Default is 100 samples\&.
.RE
.PP
\-w, \-\-wall\-clock
.RS 4
Log current wall timestamp when entry was retrieved\&.
.RE
.PP
\-T <field>, \-\-trigger\-field=<field>
.RS 4
Field name to stop trigger on\&.
.RE
.PP
\-V <value>, \-\-trigger\-threshold=<value>
.RS 4

.RS 4
Use latency tracker to trigger stop sampling\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase logging verbosity\&. Can be used multiple times\&.
