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

       -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.

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
