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
