Logging Configuration
Configuring Logging
Disk Logging
Required. Enter Y if you want logging events for a
class recorded in the NM log file; N, otherwise. The file
name that Node Management Services (NMS) uses is
NMLG
nnnn .PUB.SYS, where nnnn is a number from 0000
through 9999 . This is a common file used for logging by
all logging classes in all subsystems. At each MPE
system startup, or when a file is full, NMS creates a
new NMLG
nnnn .PUB.SYS file, naming each successive
file by incrementing
nnnn . When NMLG9999.PUB.SYS is
full, NMS names the next file NMLG
0000 .PUB.SYS. The
MPE commands RESUMENMLOG, SHOWNMLOG, and
SWITCHNMLOG are used to control logging and the log
file. These commands are described in Chapter 6 ,
“MPE Commands,” of this manual.
Refer to Table 3-1 for guidelines.
Default: Each class’s default is the recommended
setting for that class (see Table 3-1).
NOTE If you change the disk logging configuration for a subsystem, the
changes will not take effect until
that subsystem is shut down and
restarted.
Event
For display only. The type of information logged for a
class.
SNA Transport (SUB0001):
• CLAS0010: node events
— Node activation
— Link activation
— Link errors
— Internal errors
— Node shutdown
Note that if you are using an X.25 link and you want
logging information recorded, logging (console, disk,
or both) for this SNA Transport class (CLAS0010)
must be enabled, because the X.25 link uses the
logging facilities for this SNA Transport class.
• CLAS0011: protocol errors
— Packet discards/rejects
— Bad port messages
