Performance Management

The goal is to quantify, measure, report, analyse and control the utilisation or throughput of different network components.

Performance management of computer network comprises two broad functional categories - monitoring and controlling. 

Fault Management

To maintain proper operation of complex network, care must be taken that system as a whole, and each essential component individually, are in proper working order.

The goal is to log, detect, and respond to fault conditions in the network.

Configuration Management

The goal is to allow network manager to track which devices are on the managed network and the hardware and software configurations of these device. Configuration management is concerned with initialising a network and gracefully down part or all of the networks.

Accounting Management

Accounting management allows the network manager to specify log and control uses and device access to network resources.

Usage quotas, usage-based changing, allocation of resources and privileges all fall under accounting. 

Security Management

Security management is concerned with information protection and access control facilities.

The goal of security management is to control access to network resources according to well-defined policy.
