Friday Sessions • 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
The validity of the System:Processor Queue Length Counter • But usually the data is consistent with theory…
