nettlgen.conf(4) nettlgen.conf(4)
Set to 1 if writing messages to
disk is to be enabled when KL
facility is started, 0 if not.
6 Write To Disk Flag
The KL Minimum and Maximum Queue Size define the number of outstanding messages possible in
the kernel log queue. The default size is 1000.
The Maximum Log File Space determines the maximum logging file size to be allowed. Log files are
split into two parts. When an individual log file reaches the maximum specified here, the kernel logging
system deletes any existing old file, renames the current file to the old file, and starts a new file. The
default specification allows for 1 Megabyte of the kernel log file storage for one file. The rate at which the
file space fills up depends on what level of kernel logging is turned on for each subsystem, the load of the
system, number of central processor units (CPUs), and is very difficult to predict. One can use suffixes
K
and M to specify whether the size is to be in Kilo or Mega bytes. For instance, 16K = 16384 and 4M =
4096K.
The Write To Disk Flag determines if writing kernel logging messages to disk is to be enabled when the
kernel logging facility is started. Writing to disk is used to preserve the information stored inside kernel
logging messages on the non-volatile storage and to have a permanent log of kernel activity.
Subsystem Record
The subsystem record defines the information for that subsystem, and has ten fields including the tag
field. The fields are separated by colons (
: ); thus no field can contain a colon. An empty field can be
represented by the string NULL. NOTE: the information in the subsystem records should only be changed
by the subsystem using the nettlconf command during system installation. Users should not change
this information unless directed by a Hewlett-Packard support representative.
Subsystem record fields are as follows:
Field
Number Name Description
1 tag Contains SS tag string.
An integer between 0 and 1023.
Network tracing/logging facility
supports subsystems in the range
0 - 511, while Kernel logging
facility services subsystems
between 512 and 1023. This
number is set by the HP factory
and must not be changed.
2 Subsystem ID
A text string consisting of letters,
numbers, and the underscore
character. The string is set at the
factory and must not be changed.
3 Subsystem Mnemonic
Logging level for the subsystem
when the network tracing/logging
or kernel logging facility is initial-
ized. This value is different
depending on whether subsystem
is supported by NetTL or KL
facility. Please see explanation
below.
4 Initial Log Level
Set to s if the subsystem is
streams based and exists in the
kernel, k if the subsystem exists
in the kernel and non-streams
based, u if neither. Subsystems,
whose IDs are within 512 - 1023
