ActiveXperts Network Monitor ships with a large collection of PowerShell scripts and VBScript scripts to monitor and manage a network.

Use ActiveXperts Netork Monitor to monitor your virtualization servers, domains, computers and devices. It runs on a single Windows server, without agents required on the monitored systems. It has many built-in checks and also allows administrators to create custom checks using PowerShell, VBScript, WMI and SSH.

Website.ps1 - ActiveXperts Network Monitor PowerShell check

ActiveXperts Network Monitor ships with a powerful set of pre-defined checks. Each individual check has a static number of configuration items. To monitor other items, or to combine monitoring items, you can make use of custom PowerShell checks.

Most of the built-in checks have a PowerShell equivalent, implemented as a PowerShell (.ps1) script file. Out-of-the-box, each PowerShell script monitors the same items as the built-in check. Feel free to modify the script.

To add a new PowerShell-based Website monitoring check, do the following:

  • On the 'Monitor menu', open 'New Monitoring Check (Script)' and choose 'New PowerShell Check'. The 'PowerShell Check' dialog box appears;
  • In the 'Script File' selection box, select 'Website.ps1';
  • In the 'Script Parameters'group box enter the required parameters. You can also load a working sample first by clicking on the 'Click here to load a sample' link.

To customize the above monitoring check, click on the 'Edit button' next to the 'Script File' selection box. Notepad will be launched. You can now make changes to the PowerShell script.
