When I write the below code in POWER SHELL it displays the data set for "Connected planning Facilities-PRD" and "Lubes SDA - PROD" but does not display for "IAP IPP DW - PRD" which should ideally show up because the Workspace Usage for that Model is also 108.

$variable =Get-Content "export.json" | ConvertFrom-Json
#Write-Output $variable
$logs=$variable | Where-Object { $_.'Workspace Usage' -ge "75" } 
Write-Output $logs

PLEASE HELP

CodePudding user response：

The issue is all of the JSON deserialized values are strings. You are intending to do a numerical comparison and must ensure all data being compared are numeric types.

$variable | Where { [double]$_.'Workspace Usage' -ge 75 }

Output:

Workspace Name         : IAP IPP DW - PRD
Workspace Allowance    : 130
Workspace Usage        : 108.9413
Workspace Size Free    : 21.1
Percentage Utilization : 0.83801
Predicted Usage        : 146.9888958

Workspace Name         : Connected planning Facilities-PRD
Workspace Allowance    : 130
Workspace Usage        : 81.2462
Workspace Size Free    : 48.8
Percentage Utilization : 0.624970769
Predicted Usage        : 85.79967522

Workspace Name         : Lubes SDA - PROD
Workspace Allowance    : 100
Workspace Usage        : 78.5773
Workspace Size Free    : 21.4
Percentage Utilization : 0.785773
Predicted Usage        : 87.03502547

The left-hand side (LHS) of an operator influences the type of the RHS of the operator if a type conversion can be done on the RHS. Thus, by casting the LHS to [double] the number on the RHS (75) is converted to [double] also. Then the comparison executes as expected.
