ZCOM Diagnostic Message Logging Mechanism

ZCOM Diagnostic Message Logging
Mechanism
The ZCOM subsystem has a centralized diagnostic message logging
mechanism that keeps a sequenced, and time stamped record of events
generated by ZCOM and its related components. The messages are
usually displayed on a terminal device as well as being logged to files.
The actual combination of logging devices and files may be customized to
meet individual system requirements.
Figure 6-1 ZCOM Diagnostic Message Logging
The ZCOM Logical Device Manager (LDM) is responsible for collecting
and time stamping the diagnostic messages. Both the LDM and the
ZCOM Device Adapter Manager (DAM) can internally generate
messages into the log. Other messages are generated by ZCOM daemons
