Applies To: System Center 2012 R2 Operations Manager, System Center 2012 - Operations Manager, System Center 2012 SP1 - Operations Manager

System Center 2012 – Operations Manager includes the following management packs specific to network device discovery and monitoring:

  • Network Management - Core Monitoring

    This management pack contains monitoring logic for network devices.

  • Windows Client Network Discovery

    This management pack contains discovery rules to set the properties of discovered network adapters connected to computers running client operating systems.

  • Windows Server Network Discovery

    This management pack contains discovery rules to set the properties of discovered network adapters connected to computers running server operating systems.

  • Network Discovery Internal

    This management pack contains definitions and rules for discovering network devices.

  • Network Management Library

    This management pack contains definitions for core network device management.

  • Network Management Reports

    This management pack contains reports for network management.

  • Network Management Templates

Tuning Network Rules

The following rules are disabled by default. Using overrides, enable these rules only for the specific device types in your environment. To view these rules grouped by type, in the Administration workspace, scope Management Pack Objects to the network monitoring management packs listed in the previous section, and then click Rules.
