+ 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 CONFIG_SYSLOGD
- bool "syslogd"
+config CONFIG_FEATURE_ROTATE_LOGFILE
+ bool " Rotate message files"
default n
+ depends on CONFIG_SYSLOGD
help
- Please submit a patch to add help text for this item.
+ This enables syslogd to rotate the message files
+ on his own. No need to use an external rotatescript.
config CONFIG_FEATURE_REMOTE_LOG
bool " Remote Log support"
default n
depends on CONFIG_SYSLOGD
help
- Please submit a patch to add help text for this item.
+ 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 CONFIG_FEATURE_IPC_SYSLOG
bool " Circular Buffer support"
default n
depends on CONFIG_SYSLOGD
help
- Please submit a patch to add help text for this item.
+ 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 CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE
+ int " Circular buffer size in Kbytes (minimum 4KB)"
+ default 16
+ depends on CONFIG_FEATURE_IPC_SYSLOG
+ help
+ This option sets the size of the circular buffer
+ used to record system log messages.
config CONFIG_LOGREAD
bool " logread"
default y
depends on CONFIG_FEATURE_IPC_SYSLOG
help
- Please submit a patch to add help text for this item.
+ 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 CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
+ bool " logread double buffering"
+ default n
+ depends on CONFIG_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 CONFIG_KLOGD
+ bool "klogd"
+ default n
+ depends on CONFIG_SYSLOGD
+ 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 CONFIG_LOGGER
+ bool "logger"
+ default n
+ 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.
