Open Computer and Software Inventory Next Generation (OCS inventory NG) is free software that enables users to inventory IT assets. OCS-NG collects information about the hardware and software of networked machines running the OCS client program ("OCS Inventory Agent"). OCS can visualize the inventory through a web interface. Furthermore, OCS includes the capability of deploying applications on computers according to search criteria. Agent-side IpDiscover makes it possible to discover the entirety of networked computers and devices.
