Enable-AzBatchAutoScale
Enables automatic scaling of a pool.
Syntax
Enable-AzBatchAutoScale
[-Id] <String>
[[-AutoScaleFormula] <String>]
[[-AutoScaleEvaluationInterval] <TimeSpan>]
-BatchContext <BatchAccountContext>
[-DefaultProfile <IAzureContextContainer>]
[<CommonParameters>] Description
The Enable-AzBatchAutoScale cmdlet enables automatic scaling of the specified pool.
Examples
Example 1: Enable automatic scaling for a pool
$Formula = 'totalNodes=($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);';
Enable-AzBatchAutoScale -Id "MyPool" -AutoScaleFormula $Formula -BatchContext $ContextThe 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.
Parameters
-AutoScaleEvaluationInterval
Specifies the amount of time (in minutes) that elapses before the pool size is automatically adjusted according to the AutoScale formula. The default value is 15 minutes, and the minimum value is 5 minutes.
| Type: | Nullable<T>[TimeSpan] |
| Position: | 2 |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-AutoScaleFormula
Specifies the formula for the desired number of compute nodes in the pool.
| Type: | String |
| Position: | 1 |
| Default value: | None |
| Required: | False |
| 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-AzBatchAccount 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-AzBatchAccountKey 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: | AzContext, 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 enable automatic scaling.
| Type: | String |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
