Syntax

Test-AzureBatchAutoScale
    [-Id] <String>
    [-AutoScaleFormula] <String>
    -BatchContext <BatchAccountContext>
    [-DefaultProfile <IAzureContextContainer>]
    [<CommonParameters>]

Description

The Test-AzureBatchAutoScale cmdlet gets the result of an automatic scaling formula on the specified pool.

Examples

Example 1: Evaluate an autoscale formula on 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:\> $Evaluation = Test-AzureBatchAutoScale -Id "ContosoPool" -AutoScaleFormula $Formula -BatchContext $Context
PS C:\> $Evaluation.AutoScaleRun.Results
$TargetDedicated=5;$NodeDeallocationOption=requeue;totalNodes=5

The first command stores a formula in the $Formula variable for use in the example. The second command evaluates the autoscale formula on the pool that has the ID ContosoPool. The final command displays the Results by using standard dot syntax.

Parameters

-AutoScaleFormula

Specifies the formula for the desired number of compute nodes in the pool.

Type:	String
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-BatchContext

Specifies the BatchAccountContext instance that this cmdlet uses to interact with the Batch service. If you use the Get-AzureRmBatchAccount cmdlet to get your BatchAccountContext, then Microsoft Entra authentication will be used when interacting with the Batch service. To use shared key authentication instead, use the Get-AzureRmBatchAccountKeys cmdlet to get a BatchAccountContext object with its access keys populated. When using shared key authentication, the primary access key is used by default. To change the key to use, set the BatchAccountContext.KeyInUse property.

Type:	BatchAccountContext
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-DefaultProfile

The credentials, account, tenant, and subscription used for communication with azure.

Type:	IAzureContextContainer
Aliases:	AzureRmContext, AzureCredential
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Id

Specifies the object ID of the pool for which to test automatic scaling.

Type:	String
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

Inputs

String

BatchAccountContext

Parameters: BatchContext (ByValue)
