A structured database, often hierarchical, contains definitions of managed objects within a network or system. This repository allows network management systems to monitor and control devices and applications by querying for specific data points and issuing commands according to pre-defined parameters. For instance, a network administrator can use a tool referencing this data structure to check the bandwidth utilization of a router, or to remotely reboot a server based on CPU load thresholds.
The significance of this organized data structure lies in its ability to provide a standardized method for accessing and interpreting management information. This standardization facilitates interoperability between different network devices and management platforms. Historically, its development enabled the creation of scalable and manageable networks, moving away from proprietary management solutions that were difficult to integrate and maintain.
