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 sub-
system using the nettlconf command during system installation. Users should not change this infor-
mation 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. Net-
work tracing/logging facility supports
subsystems in the range 0 - 511, while
Kernel logging facility services subsys-
tems 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 charac-
ter. 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 initialized. 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. Sub-
systems, whose IDs are within 512 -
1023 range, i.e. subsystems supported
by KL facility, should have Subsystem
Type to be k.
5 Subsystem Type
Name of the shared library file con-
taining the subformatter functions
listed below.
