Interpreting NT Queue Length Measurements, Yiping, Bolker & Yefim, BMC Software Friday 9:45 am

Research questions the validity of the System:Processor Queue Length Counter At low utilization, the Processor Queue Length

can be a relatively high number

Interpreting NT Queue Length Measurements

The validity of the System:Processor 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 System:Processor 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

But usually the data is consistent with theory…
