Operations Bridge Manager (OBM) is the core component of the Operations Bridge Suite that dynamically and automatically discovers and correlates data, event topology, and metrics. As part of the Operations Bridge, it consolidates all IT infrastructure monitoring in a central event console, and relates the events to the IT services that depend on that infrastructure.
OBM combines events from Application Management components with events from System and Network products, such as OM and Network Node Manager i. This enables you to keep track of all the events that occur in your monitored environment.
