11
Friday Sessions

• Interpreting NT Queue Length Measurements,
• Yiping, Bolker Yefim, BMC Software
• Friday 945 am
• Research questions the validity of the
  SystemProcessor Queue Length Counter
• At low utilization, the Processor Queue Length
  can be a relatively high number

12
Interpreting NT Queue Length Measurements

• The validity of the SystemProcessor Queue Length
  Counter
• At low utilization, the observed Processor Queue
  Length can be a relatively high number
• Instantaneous Counter (i.e., sampled value)
• Application of Heisenberg Uncertainty Principle
  measurement tool can get in the way of the
  measurement data
• e.g.,
• dmperfss collection thread always observed in the
  Running state

The validity of the SystemProcessor Queue Length
Counter

• Possible low utilization effect
• Redesign the thread dispatching logic in NTSMF
  2.2.5 to reduce the impact of the threaded
  collector
• Currently, in versions 2.2.3 and 2.2.4, all
  collection threads (one per Perflib DLL) are
  dispatched at one time
• In version 2.2.5, collection threads will be
  dispatched in sequence

The validity of the SystemProcessor Queue Length
Counter

• But usually the data is consistent with theory
