The Metric Weights tab describes the current weights applied to measurement metrics. If the weights do not sum to 100, the workload manager uses proportionate, adjusted values that do sum to 100.
User connections – the capacity of an instance to accept a new connection, based on resource availability.
CPU utilization – the capacity of an instance to accept additional work.
Run-queue length – the number of runnable tasks on a system. Run-queue length measures the processing backlog, and is a good indicator of relative response time.
I/O load – outstanding asynchronous I/Os.
Engine deficit – the difference in the number of online engines among instances in the cluster.
Engine deficit is measurable only when instances in
the cluster have unequal numbers of engines. Engine deficit adds
a metric for maximum relative capacity to the load score.
User metric – an optional customer-supplied metric specific to the user’s environment.
Make sure the load scores you specify add up to 100.
