- 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.
