   8 config BUSYBOX_CONFIG_SYSLOGD
   9         bool "syslogd"
  10         default y
  11         help
  12           The syslogd utility is used to record logs of all the
  13           significant events that occur on a system.  Every
  14           message that is logged records the date and time of the
  15           event, and will generally also record the name of the
  16           application that generated the message.  When used in
  17           conjunction with klogd, messages from the Linux kernel
  18           can also be recorded.  This is terribly useful,
  19           especially for finding what happened when something goes
  20           wrong.  And something almost always will go wrong if
  21           you wait long enough....

  23 config BUSYBOX_CONFIG_FEATURE_ROTATE_LOGFILE
  24         bool "  Rotate message files"
  25         default y
  26         depends on BUSYBOX_CONFIG_SYSLOGD
  27         help
  28           This enables syslogd to rotate the message files
  29           on his own. No need to use an external rotatescript.
  30
  31 config BUSYBOX_CONFIG_FEATURE_REMOTE_LOG
  32         bool "  Remote Log support"
  33         default y
  34         depends on BUSYBOX_CONFIG_SYSLOGD
  35         help
  36           When you enable this feature, the syslogd utility can
  37           be used to send system log messages to another system
  38           connected via a network.  This allows the remote
  39           machine to log all the system messages, which can be
  40           terribly useful for reducing the number of serial
  41           cables you use.  It can also be a very good security
  42           measure to prevent system logs from being tampered with
  43           by an intruder.
  44
  45 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  46         bool "  Circular Buffer support"
  47         default y
  48         depends on BUSYBOX_CONFIG_SYSLOGD
  49         help
  50           When you enable this feature, the syslogd utility will
  51           use a circular buffer to record system log messages.
  52           When the buffer is filled it will continue to overwrite
  53           the oldest messages.  This can be very useful for
  54           systems with little or no permanent storage, since
  55           otherwise system logs can eventually fill up your
  56           entire filesystem, which may cause your system to
  57           break badly.
  58
  59 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE
  60         int "    Circular buffer size in Kbytes (minimum 4KB)"
  61         default 16
  62         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  63         help
  64           This option sets the size of the circular buffer
  65           used to record system log messages.
  66
  67 config BUSYBOX_CONFIG_LOGREAD
  68         bool "  logread"
  69         default y
  70         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  71         help
  72           If you enabled Circular Buffer support, you almost
  73           certainly want to enable this feature as well.  This
  74           utility will allow you to read the messages that are
  75           stored in the syslogd circular buffer.
  76
  77 config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
  78         bool "    logread double buffering"
  79         default n
  80         depends on BUSYBOX_CONFIG_LOGREAD
  81         help
  82           'logread' ouput to slow serial terminals can have
  83           side effects on syslog because of the semaphore.
  84           This option make logread to double buffer copy
  85           from circular buffer, minimizing semaphore
  86           contention at some minor memory expense.
  87
  88 config BUSYBOX_CONFIG_KLOGD
  89         bool "klogd"
  90         default y
  91         depends on BUSYBOX_CONFIG_SYSLOGD
  92         help
  93           klogd is a utility which intercepts and logs all
  94           messages from the Linux kernel and sends the messages
  95           out to the 'syslogd' utility so they can be logged.  If
  96           you wish to record the messages produced by the kernel,
  97           you should enable this option.
  98
  99 config BUSYBOX_CONFIG_LOGGER
 100         bool "logger"
 101         default y
 102         help
 103             The logger utility allows you to send arbitrary text
 104             messages to the system log (i.e. the 'syslogd' utility) so
 105             they can be logged.  This is generally used to help locate
 106             problems that occur within programs and scripts.
