1 About Lua About Lua Lua is a powerful light-weight programming language designed for extending applications. Lua is also frequently used as a general-purpose, stand-alone language. Lua is free software. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, interpreted from byte codes, and has automatic memory management with garbage collection, making it ideal for configuration, scripting, and rapid prototyping. KNM and Lua Kaseya Network Monitor includes support for the Lua scripting language (www.lua.org). Customers can create custom made monitors to test systems and equipment not supported by any current monitoring solution. New monitors, actions and events can be created and tested in the development environment provided by Kaseya, before they are exported and used in Kaseya Network Monitor. 2 Introduction This documentation covers the Kaseya Network Monitor Lua API. This documentation do not cover the Lua language, for more information about the Lua language visit http://www.lua.org. KNM uses Lua 5.0. 3 Copyright information Copyright © 2001-2011 Kaseya International Limited. All rights reserved.

This makes it possible to make Lua scripts that have the same look and feel like native monitor types. Reserved function names There are two reserved function names, used by KNM to query information. These function names can not be used for any other purpose. OnConfigure This function is called by KNM to have the script populate a LuaScriptConfigurator class instance. The information is then used to create a user interface for the script. The name of the instance must be « Config » (note that casing) so KNM may find it in the Lua stack when the function returns. OnEnumerate Each field in the user interface can be enumerated, KNM calls the OnEnumerate function to have the script populate a data strcture, LuaScriptEnumResult, with values the user can select. The OnEnumerate have one parameter, sFieldToEnum, that is used by the script to determin which field/argument to provide enumeration results for. The returned instance must be named « Enum » (note the casing). The entry point The advanced script model requires the OnConfigure function to set the name of the entry point function. This function is called by KNM to start the execution of the script. The name of the entry point is by default « main » but can be set by the programmer to any name except the reserved function names. 4.2 Simple script The simple script model has been used in KNM since the first release and should now be seen as deprecated. Its maintained for compatibility with older scripts. 4.3 Object context Functions are relative to the object context. All calls that are accessing resources is relative to the parent object. For example, if the scripts opens a file the path supplied to the open function must be relative to the object. 4.4 Result When an script exit it needs to tell KNM if the test was successful or not. A global function are provided for this purpose, SetExitStatus . SetExitStatus is mandatory and must be called before the script terminates. 5 Global functions Global functions is functions not associated with an object. There is a number of global functions in the KNM Lua API, some is required to call when a scripts exit. 5.1 ConvertFromUTF16 string ConvertFromUTF16(local UTF16data,int iSize) Return values A 8 bit string converted from the UTF16 string. Parameters UTF16data UTF16 (double byte) string read by TLuaFile::ReadData. iS ize Size of string. Remarks The function only accepts data created by the TLuaFile::ReadData function. 5.2 FormatErrorString string FormatErrorString(int iError) Return values A string describing the error code iError. Parameters iEr r or An Windows error code obtained previously by calling the GetLastError function. Remarks This function can be useful supplying meaningful text to the user instead of an error code. 5.3 GetAccountPassword string GetAccountPassword() Return values The password of the logon account selected in the monitor. Remarks A calling application can pass an account to a Lua script for customize logon behaviour. Note that this function always returns an empty string in the IDE and is only meaningful in a script executed by KNM. …….
