Description
The Test-AzBatchAutoScale cmdlet gets the result of an automatic scaling formula on the specified pool.
Examples
Example 1: Evaluate an autoscale formula on 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);';
$Evaluation = Test-AzBatchAutoScale -Id "ContosoPool" -AutoScaleFormula $Formula -BatchContext $Context
$Evaluation.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.
Parameter properties
| Type: | String |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
(All)
| Position: | 1 |
| Mandatory: | True |
| Value from pipeline: | False |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | 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.
