Windows Script Monitor

Windows Script Monitors are SAM component monitors that can run a PowerShell, Perl, VBScript, or any other Windows script against SNMP- or WMI-managed nodes, and then process the script's exit code and text output.

By default, scripts run locally on the Orion Server, which usually serves as the Main Polling Engine, or on the Additional Polling Engine (APE) to which the node is assigned. To execute scripts on the managed node itself, you can either install the Orion Agent for Windows on the node, or rewrite the script in PowerShell utilizing WinRM.

  • With agentless polling, the local execution of the script is local and the script is executed on the polling engine.
  • For Orion agent polling, the local script execution allows the script to be run on the target node.

To learn about creating custom scripts, see these topics in the SAM Custom Template Guide:


The statistic for this component monitor is the value returned by the script. This monitor can return up to ten output pairs — 10 statistic values and 10 optional messages. If you exceed the maximum allowed, remove the excess output pairs or they are ignored.

Script Monitor Formatting

At least one message and statistic is required. The statistic must be a valid integer and be able to be converted to double, otherwise it is handled as Not as Number (NaN). There is no maximum length for the message; however, only alphanumeric characters and the underscore are allowed.

Field descriptions


A default description of the monitor. You can override the default description by adding to or replacing the text, which will then be automatically saved. The variable to access this field is ${UserDescription}.

Component Type

The type of monitor you are using.

Enable Component

Determines if the component is enabled. Disabling this component leaves it in the application as deactivated and does not influence application availability or status.

Credential for Monitoring

Select a Windows credential that can log into the Orion server, and has sufficient rights on the target node (which may be the Orion server itself, depending upon your application) to do whatever the script needs to do. For example, if the script does something with WMI, the credentials also need WMI rights on the target node.

Click a credential in the list, or use the <Inherit credential from node> option. If the credential you need is not in the credentials list, add it in the Credentials Library. See Understand the Credentials Library for details.

Script Arguments

Specify arguments to pass to the script. You may include the variables ${IP}, ${USER}, and ${PASSWORD}, which are replaced respectively by the IP address of the target node, the credential user name, and the credential password.

Script Engine

Specify the scripting language to be used. The default value is vbscript. Click here for a list of supported scripting engines in the SAM Custom Template Guide.

Script Body

Click Edit to open the script editing window where you can type or paste script text.

Status Roll-Up

Choose how you want the monitor to report the returned results based on the output provided by the script. With the ability to have multiple values returned, selecting how your scripts report back to you offers more flexibility. The default selection is “Show worst status."

User Notes

Add notes for easy reference. You can access this field by using the variable, ${UserNotes}.
