# additional logs scattered throughout your dbspaces if you have set
# DYNAMIC_LOGS to 2 (which is also the default). All these dbspaces will
# then be considered 'critical' (because they contain a logical log), so if

# However if you have already configured the same number of CPU VPs as physical processors available in the machine, you might have to add more physical processors or investigate other performance tuning activities. This domain inspector allows you to specify the number of samples that should be taken before computing the average number of threads on the ready queue. This ensures that the computed value is more representative.
