Introduction

This Wiki is deprecated and we are are currrently migrating remaining pages into product documentation (Admin Guide, NXSL Guide)

WARNING: This page is no longer updated. Please visit NetXMS Scripting Language for current version of the documentation.

In many parts of the system, fine tuning can be done by using NetXMS built-in scripting language called NXSL (stands for NetXMS Scripting Language). NXSL was designed specifically to be used as embedded scripting language within NetXMS, and because of this has some specific features and limitations. Most notable is very limited access to data outside script boundaries – for example, from NXSL script you cannot access files on server, nor call external programs, nor even access data of the node object other than script is running for without explicit permission. NXSL is interpreted language – scripts first compiled into internal representation (similar to byte code in Java), which than executed inside NXSL VM.
