What does NNM mean in NETWORKING

A Network Node Manager (NNM) is a comprehensive tool used to manage and monitor networking component performance in real-time. It helps network administrators identify and resolve performance-related issues quickly and accurately.

Using a NNM helps to automate many administrative tasks within the network, such as system configuration, end-user service monitoring, traffic analysis, and fault isolation. It also provides an extensive array of data gathering capabilities that enable administrators to stay on top of their network's performance.

The NNM monitors performance by using various sensors to detect problems such as low bandwidth utilization, packet latency, or elevated error rates. These parameters are then correlated with the different nodes in the network allowing for deeper investigations into specific areas of concern.

NNMs provide alerts when certain thresholds have been reached or exceeded. These alerts can be tailored according to the preferences of each user allowing them to subscribe to relevant metrics and receive notifications about performance degradation or system outages if they occur.

The NNM allows you to assign priority levels to certain events based on how critical they are for maintaining normal operations within your network. This allows administrators to focus their efforts on resolving the most important issues first while ensuring other potential threats aren’t overlooked in the process.

Depending on your specific implementation, your NNM may have features such as NetFlow data collection, SNMP polling, and syslog parsing that allow it to collect data from distributed sources across your entire network environment. This raw data can then be used by administrators to diagnose possible problems before they arise or create reports that provide insight into overall performance trends over time.
