Using the Event Management Service (EMS) With
Tandem FTAM
Using the Event Management Service (EMS) With
Tandem FTAM
EMS provides event collection, event logging, and event distribution facilities for
Tandem FTAM. EMS enables you to monitor events that occur during the operation of
Tandem FTAM and other subsystems. This subsection discusses EMS in relation to
Tandem FTAM. For detailed information on EMS itself, see the EMS Manual. The event
messages that Tandem FTAM can issue are described in the Operator Messages Manual.
The APLMGR, initiator, and responder processes detect significant events, generate
event messages, and send them to an EMS collector, which logs the messages. You can
view all or selected event messages reported to EMS. You can write filters to filter event
messages for selective printing or display on the operator console. You can use
information retrieved from EMS to monitor Tandem FTAM and to recognize critical
problems.
Each Tandem system supports only one primary event-message collector, named $0,
which is initiated at system generation. The primary collector provides a central
collection point for all events from all subsystems in a system.
An alternate collector provides functions similar to those supplied by $0 but maintains
its own log files. The separation of events into separate log files speeds up event
processing because a network application program does not have to read a single large
file containing many events unrelated to that application.
Tandem FTAM supports the primary collector, $0, and an alternate collector; events can
be sent to one or the other, or to both. For example, events that have bearing on the
operational status of subsystem processes or that signify errors might be reported to the
primary collector. Events that are likely to have importance for data tracking and
diagnostics might be reported to an alternate collector. Only one alternate collector is
allowed on each Tandem FTAM subsystem. However, two or more Tandem FTAM
subsystems may use the same alternate collector.
