PowerShell

PowerShell provides remote access of the monitored device and the ability to leverage PowerShell modules and .NET libraries installed there.

Prerequisites

WhatsUp Gold uses a 32-bit (in other words, "x86") PowerShell engine. Only 32-bit PowerShell snap-ins are supported and 64-bit only snap-ins will not function properly. Snap-ins that work on both 32-bit and 64-bit operating systems are configured for 64-bit systems by default and must be manually configured for 32-bit PowerShell engine to function properly with WhatsUp Gold.

Remote Connection Requirements

Ensure the following are in place for enabling the WhatsUp Gold machine to connect using PowerShell to the destination (polled) device.

Monitor Configuration

Configuration fields for this active monitor include:

Available Monitor Objects and Attributes

PowerShell active monitor scripts have two instantiated session objects available.

Getting or Setting Properties for a Context Object

You can fetch values for context properties using PowerShell active monitor scripts.

Syntax

Property-Value = Context.GetProperty("Property-Name")

Context.SetProperty("Property-Name","Property-Value")

Example

$DeviceIpAddress = $Context.GetProperty("Address")

$Context.SetProperty("Timeout", "180")

Setting Result String and Monitor Status Indicator

The result string you set will be added to the description in the monitor's status change. The status flag you set (0, 1) up/down determines the indicator shown in the State Change Timeline.

# After a successful Get of the deviceIP, Set as result and set success flag ...

$Context.SetResult(0, "Device IP address is: " + $DeviceIpAddress)

Example: Check if Service is Running

Create a PowerShell active monitor that shows status of up only if DNS client is running using stored credentials.

# Device to Poll

$DeviceIpAddress = $Context.GetProperty("Address")

# Set the computer name directly, or...

# $CompName = mydb02.corpnet.example.com (for example)

# ...get it using WMI...

$WmiRes = Invoke-Command -ComputerName $DeviceIpAddress -ScriptBlock { Get-WmiObject Win32_Computersystem }

$CompName = $WMIRes.PSComputerName

# Run command on remote device

$PsResult = Invoke-Command -ComputerName $DeviceName -ScriptBlock { Get-Service | where { $_.Name -match "Dnscache" } }

# Check for condition of 'running'

if ($PsResult.Status -match 'Running') {

$RespondingMessage = "Process '" + $processName + "' running on " + $DeviceIpAddress + " is responding."

$Context.SetResult(0, $RespondingMessage )

} else {

$NotRunningMessage = "Process '" + $processName + "' running on " + $DeviceIpAddress + " is not responding."

$Context.SetResult(1, $NotRunningMessage )

}
