Frequently used utilities for Python

Background load:

• LOADGEN_WORK_BREAK - sets frequency of loadgen
  • DEFAULT -> 600
  • 600 -> 10min break between cycles (intermittent)
  • 15 -> 15s break (near-constant)
• LOADGEN_CPU_INTENSITY - sets intensity of loadgen CPU usage
  • DEFAULT -> 1 (low)
  • .01 -> high CPU load
  • .35 -> moderate CPU load
  • 1.25 -> low CPU load
• LOADGEN_MAX_PRIMES - set how long the load calculation takes (important for request-based loads)
  • DEFAULT -> 25
  • 1 -> usually quick (seconds)
  • 25 -> ~4-5min
• LOADGEN_RANDOMIZE_WORK_BREAK - randomizes the frequency (work_break)
  • When True, work_break ranges from 15 to LOADGEN_WORK_BREAK
• LOADGEN_MEMORY_MB - memory consumption
  • DEFAULT -> 1

Request load:

• REQUEST_CPU_INTENSITY
  • DEFAULT -> 0 (random)
  • Setting to 0 uses random range from 0.01-1.0
• REQUEST_MEMORY_MB
  • DEFAULT -> .1
• REQUEST_MAX_PRIMES
  • DEFAULT -> 1
