mountpoint.vbs - vbscript script by ActiveXperts Software
mountpoint.vbs checks whether Windows Mount Point has sufficient space.
Use mountpoint.vbs directly from ActiveXperts Network Monitor; in the Manager's 'Monitor' menu, select 'New Check (Script)' and select mountpoint.vbs. Configure the required parameter, or press 'Load a working sample'.
In ActiveXperts Network Monitor, Administrators can use three different scripting languages: Powershell, VBScript and SSH.

Function CheckMountPointFreeSpace( strHost, strCredentials, strMountPoint, nRequiredSpaceMB )
' Description:
' This function checks if a Windows Mount Point has enough space left.
' Parameters:
' 1) strHost As String - Hostname or IP address of the computer you want to monitor
' 2) strCredentials As String - Specify an empty string to use Network Monitor service credentials.
' To use alternate credentials, enter a server that is defined in Server Credentials table.
' (To define Server Credentials, choose Tools->Options->Server Credentials)
' 3) strMountPoint As String - The Mount point you want to check.
' 4) nRequiredSpaceMB As Int - The freespace required on the MountPoint
' Usage:
' CheckMountPointFreeSpace( "<Hostname | IP>", "<Empty String | Server>", "<MountPoint>", <RequiredSpaceMB> )
' Sample:
' CheckMountPointFreeSpace( "localhost", "", "C:\myMountPoint", 25000)
