“`powershell

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

“`
### Step 3: Retrieve Host Information
Once connected, we can retrieve and display the status of all ESXi hosts.
“`powershell

# Get a list of all ESXi hosts and display their power state
$hosts = Get-VMHost
foreach ($host in $hosts) {
    Write-Host "Host: $($host.Name) - State: $($host.State) - CPU Usage: $($host.CpuUsageMhz) MHz - Memory Usage: $($host.MemoryUsageMB) MB"
}

“`
### Step 4: Disconnect from the ESXi Host
Finally, its important to disconnect from the ESXi host after retrieving the necessary information to free up resources.
“`powershell

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