I'm trying to understand the following formula.
startingNumberOfVMs = 1;maxNumberofVMs = 25;pendingTaskSamplePercent = $PendingTasks.GetSamplePercent(180 * TimeInterval_Second);pendingTaskSamples = pendingTaskSamplePercent < 70 ? startingNumberOfVMs : avg($PendingTasks.GetSample(180 * TimeInterval_Second));$TargetDedicatedNodes=min(maxNumberofVMs, pendingTaskSamples);
We start with 1 node, then if pending task percentage < 70, it would automatically increase amount of node.
But how is 70% calculated? what slash what equal 70?
Someone can give an step by step example on how to scale from 1 to 25 node?
