Question

I am just trying to add an additional lines to send an email to an DL when the "$R.status is down and $R status is resolved, I am just not getting the syntax correctly on where I can use the below lines to send an email on the below PS script. can someone guide me through that?

[CmdletBinding()]
Param (
	[string[]]$To = @("abc.com")
)

# Mail it out
$MailSplat = @{
    To         = $To
    From       = "no.com"
    Subject    = $json
    Body       = $json.summary
    SMTPServer = "hub.com"
    BodyAsHtml = $true
}

Send-MailMessage @MailSplat

$VIPResults = Get-NSVIPAlertingStatus

if ($null -ne $VIPResults)
{
    foreach ($R in ($VIPResults | Where-Object Status -notmatch "Up|Out Of Service"))
    {
        if ($R.status -eq "Down")
        {
            $Stauts = $R.Status
            $Severity = "5"
        }
        Elseif ($R.status -eq "Resolved")
        {   
            $Stauts = $R.Status

        }

        Write-Verbose "$(Get-Date): Send Alert: Netscaler $($R.name) on $($R.netscalername) is $($R.Status)" -Verbose

Changing from a function to in-line code is something you could have easily done yourself.

$VIPResults = Get-NSVIPAlertingStatus

if ($null -ne $VIPResults) {
    foreach ($R in ($VIPResults | Where-Object Status -NotMatch "Up|Out Of Service")) {
        if ($R.status -eq "Down") {
            $Stauts = $R.Status         # "status" is misspelled
            $Severity = "5"
        }
        Elseif ($R.status -eq "Resolved") {   
            $Stauts = $R.Status         # "status" is misspelled
            $Severity = "0"
        }

        Write-Verbose "$(Get-Date): Send Alert: Netscaler $($R.name) on $($R.netscalername) is $($R.Status)" -Verbose
        $JSON = @"
        {
            "summary": "Netscaler $($R.name) on $($R.netscalername) is $($R.Status)",
            "node": "$($R.netscalername)",
            "team": "",
            "severity": $Severity,
            "sop_link": "",
            "category": "Netscaler component $($R.name)",
            "integration": "" 
        }
"@
        
        Write-Verbose "$(Get-Date):se" -Verbose
        # Mail it out
        $To = "******@abc.com"
        $MailSplat = @{
            To         = $To
            From       = "******@no.com"
            Subject    = "Netscaler $($R.name) on $($R.netscalername) is $($R.Status)"
            Body       = $JSON
            SMTPServer = "hub.com"
            BodyAsHtml = $true
        }
        Send-MailMessage @MailSplat
        Invoke-WebRequest -Uri http:\\test.com -Method Post -Body \$Json -ContentType application/json -Verbose
    }
}

The stated goal is clear (too send an email), but how (in-line or function) and what (just the status for a single netscaler?) isn't.

Here's one way:

Function SendAnEmail {
    [CmdletBinding()]
    Param (
        [string[]]$To = @("abc.com"),
        $Json
    )
    $status = ConvertFrom-Json $Json

    # Mail it out
    $MailSplat = @{
        To         = $To
        From       = "no.com"
        Subject    = "Netscaler status"
        Body       = $status.summary
        SMTPServer = "hub.com"
        BodyAsHtml = $true
    }

    Send-MailMessage @MailSplat
}
