python storperf/main.py

Command line options:

• -t or –target
• -w or –workload
• -s or –nossd
• -c or –nowarm
• verbose optional Emit periodic output describing the current read and write latency, and measured IOPS.

If specified from command line, the option is in the format –option=. For ReST, it is embedded in the URL as &option=

• target=[device or path] Optional The path to either an attached storage device (/dev/vdb, etc) or a directory path (/opt/storperf) that will be used to execute the performance test. In the case of a device, the entire device will be used. If not specified, the current directory will be used.
• workload=[workload module] Optional If not specified, the default is to run all workloads. The workload types are:
  • rs: 100% Read, sequential data
  • ws: 100% Write, sequential data
  • rr: 100% Read, random access
  • wr: 100% Write, random access
  • rw: 70% Read / 30% write, random access
• nossd optional Do not perform SSD style preconditioning.
• nowarm optional Do not perform a warmup prior to measurements.
• report= [job_id] optional Query the status of the supplied job_id and report on metrics. If a workload is supplied, will report on only that subset.

The report command returns a JSON string with the job status (running or completed). If still running:

{
  "version": 1.0
  "status": running
  "start": 1448905682
}

If completed:

{
  "version": 1.0,
