ActiveXperts Network Monitor is designed to allow operators to write custom check routines and add these to the configuration. ActiveXperts has selected VBScript as the standard scripting language for its Network Monitor product because of its wide acceptance: VBScript is the most popular scripting language in Windows environments.
A VBScript function accepts the following parameters:
- VBScript Filename - UNC path of the VBScript file. The script should contain a function as specified in the Function name field.
This function should return True (-1) in case of success, False (0) in case of an error, or (1) in case the result cannot be indicated( also called: 'Uncertain');
- VBScript Function - The function name. The function must be implemented in the VBScript Filename as specified above;
- Parameter1 .. Parameter6 - Arguments to the function call; these arguments depend on the function you call. For instance, the 'CheckAccountDisabled' function requires two parameters: the Domain name and the Account name;
- Advanced Settings:Timeout - You can specify a timeout for a VBScript check. If the script takes longer than the timeout (in seconds), the function is aborted and an 'Unknown' result is reported. By default, there's no timeout used;
- Advanced Settings:Block script after a bad operation - If a script crashes, for instance because of bad programming, you can block the script so that it will be executed the next time. By default, this option is enabled.
