Enable-​Azure​Batch​Auto​Scale

Enables automatic scaling of a pool.

Syntax

Enable-AzureBatchAutoScale
      [-Id] <String>
      [[-AutoScaleFormula] <String>]
      [[-AutoScaleEvaluationInterval] <TimeSpan>]
      -BatchContext <BatchAccountContext>
      [<CommonParameters>]

Description

The Enable-AzureBatchAutoScale cmdlet enables automatic scaling of the specified pool.

Examples

Example 1: Enable automatic scaling for a pool

PS C:\>$Formula = 'totalNodes=($CPUPercent.GetSamplePercent(TimeInterval_Minute*0,TimeInterval_Minute*10)<0.7?5:(min($CPUPercent.GetSample(TimeInterval_Minute*0, TimeInterval_Minute*10))>0.8?($CurrentDedicated*1.1):$CurrentDedicated));$TargetDedicated=min(100,totalNodes);';
PS C:\> Enable-AzureBatchAutoScale -Id "MyPool" -AutoScaleFormula $Formula -BatchContext $Context

The first command defines a formula, and then saves it to the $Formula variable.

The second command enables automatic scaling on the pool named MyPool using the formula in $Formula.

Required Parameters

-BatchContext
