menu "System Logging Utilities"
config SYSLOGD
bool "syslogd"
default n
help
The syslogd utility is used to record logs of all the
significant events that occur on a system. Every
message that is logged records the date and time of the
event, and will generally also record the name of the
application that generated the message. When used in
conjunction with klogd, messages from the Linux kernel
can also be recorded. This is terribly useful,
especially for finding what happened when something goes
wrong. And something almost always will go wrong if
you wait long enough....
config FEATURE_ROTATE_LOGFILE
bool "Rotate message files"
default n
depends on SYSLOGD
help
This enables syslogd to rotate the message files
on his own. No need to use an external rotatescript.
config FEATURE_REMOTE_LOG
bool "Remote Log support"
default n
depends on SYSLOGD
help
When you enable this feature, the syslogd utility can
be used to send system log messages to another system
connected via a network. This allows the remote
machine to log all the system messages, which can be
terribly useful for reducing the number of serial
cables you use. It can also be a very good security
measure to prevent system logs from being tampered with
by an intruder.
config FEATURE_SYSLOGD_DUP
bool "Support -D (drop dups) option"
default n
depends on SYSLOGD
help
Option -D instructs syslogd to drop consecutive messages
which are totally the same.
config FEATURE_IPC_SYSLOG
bool "Circular Buffer support"
default n
depends on SYSLOGD
help
When you enable this feature, the syslogd utility will
use a circular buffer to record system log messages.
When the buffer is filled it will continue to overwrite
the oldest messages. This can be very useful for
systems with little or no permanent storage, since
otherwise system logs can eventually fill up your
entire filesystem, which may cause your system to
break badly.
config FEATURE_IPC_SYSLOG_BUFFER_SIZE
int "Circular buffer size in Kbytes (minimum 4KB)"
default 16
range 4 2147483647
depends on FEATURE_IPC_SYSLOG
help
This option sets the size of the circular buffer
used to record system log messages.
config LOGREAD
bool "logread"
default y
depends on FEATURE_IPC_SYSLOG
help
If you enabled Circular Buffer support, you almost
certainly want to enable this feature as well. This
utility will allow you to read the messages that are
stored in the syslogd circular buffer.
config FEATURE_LOGREAD_REDUCED_LOCKING
bool "Double buffering"
default n
depends on LOGREAD
help
'logread' ouput to slow serial terminals can have
side effects on syslog because of the semaphore.
This option make logread to double buffer copy
from circular buffer, minimizing semaphore
contention at some minor memory expense.
config KLOGD
bool "klogd"
default n
help
klogd is a utility which intercepts and logs all
messages from the Linux kernel and sends the messages
out to the 'syslogd' utility so they can be logged. If
you wish to record the messages produced by the kernel,
you should enable this option.
config LOGGER
bool "logger"
default n
select FEATURE_SYSLOG
help
The logger utility allows you to send arbitrary text
messages to the system log (i.e. the 'syslogd' utility) so
they can be logged. This is generally used to help locate
problems that occur within programs and scripts.
