### Step 1: Load VMware PowerCLI Module
Before interacting with the ESXi environment, we must ensure that the VMware PowerCLI module is loaded into the PowerShell session.
“`powershell

# Load VMware PowerCLI module
Import-Module VMware.PowerCLI -ErrorAction Stop

“`
### Step 2: Connect to the ESXi Host
Well connect to the ESXi host using valid credentials. Make sure to replace ``, ``, and `` with your actual ESXi credentials.
“`powershell

# Define connection parameters
$esxiHost = "<ESXi_Host>"
$username = "<Your_Username>"
$password = "<Your_Password>"
# Securely convert the password
$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$credentials = New-Object System.Management.Automation.PSCredential ($username, $securePassword)
# Connect to the ESXi host
Connect-VIServer -Server $esxiHost -Credential $credentials -ErrorAction Stop

“`
### Step 3: Retrieve and Display VM Health Status
After connecting successfully, we can retrieve the health status of all virtual machines. The cmdlet will display each VMs name and its overall status.
“`powershell

# Retrieve all VMs and their health status
$vmList = Get-VM
foreach ($vm in $vmList) {
    $status = $vm.ExtensionData.Runtime.PowerState
    $health = $vm.ExtensionData.Summary.QuickStats
    Write-Host "VM Name: $($vm.Name) - Power State: $status - CPU Usage: $($health.OverallCpuUsage) MHz - Memory Usage: $($health.GuestMemoryUsage) MB"
}

“`
### Step 4: Disconnect from the ESXi Host
Its crucial to disconnect from the ESXi host after completing your operations to ensure the management session is closed properly.
“`powershell

# Disconnect from the ESXi host
Disconnect-VIServer -Server $esxiHost -Confirm:$false

“`
