Netcool/OMNIbus components
Operation of the Netcool/OMNIbus relies on the following three major components:
• ObjectServer
• Probes
• Desktop tools
ObjectServer
The ObjectServer is the in-memory database server at the core of Netcool/OMNIbus. Alert
information is forwarded to the ObjectServer from external programs such as probes, monitors, and
gateways, stored and managed in database tables, and appears in the event list.
Deduplication and automation
A single device might generate the same error repeatedly until the problem is dealt with. The
ObjectServer uses deduplication to insure that alert information generated from the same source is not
duplicated.
Repeated alerts are identified and stored as a single alert to reduce the amount of data in the
ObjectServer.
Use automation to detect changes in the ObjectServer and execute automated responses to these
changes. This enables the ObjectServer to process alerts without requiring an operator to take action.
Probes
Probes connect to an event source, detect and acquire event data, and forward the data to the
ObjectServer as alerts. Probes use the logic specified in a rules file to manipulate the event elements
before converting them into fields of an alert in the ObjectServer alerts status table.
Each probe is uniquely designed to acquire event data from a specific source. Probes can acquire
data from any stable data source, including devices, databases, and log files.
Desktop tools
The desktop is an integrated suite of graphical tools used to view and manage alerts, and to
configure how alert information is presented. Desktop tools are available on both UNIX and Windows
platforms.
Alert information is delivered in a format that allows users to quickly determine the availability of
services on a network. When an alert cause has been identified, desktop tools enable users to resolve
issues quickly.
