Event Adapter components

Each adapter, regardless of type, consists of the following components:

• Parser—The parser separates the data stream (source events) into records and fields by using regular expressions. The LogFile Adapter, the SNMP Adapter, and the Perl EventLog Adapter for Windows are preconfigured and include dedicated parsers. The IP Adapters require more extensive configuration, including the option to choose from a number of parsers. The BMC Event Log Adapter for Windows does not use a parser.
• Map file—The map file designates how the parsed data is mapped to event slots (fields in an event record). Map files can also be used to filter out unwanted events and to change or add data in the source event. The BMC Event Log Adapter for Windows does not use a map file.
• Event class definitions—The mapped events must be translated into Basic Recorder of Objects in C (BAROC) language structures. The translated event data becomes a cell event instance.
• Configuration—The adapter configuration defines an instance of an adapter type, the parser to use, parameters specific to an adapter type, and the cell to which the adapter forwards the events.
