   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....
  22
  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_SYSLOGD_DUP
  46         bool "Support -D (drop dups) option"
  47         default n
  48         depends on BUSYBOX_CONFIG_SYSLOGD
  49         help
  50           Option -D instructs syslogd to drop consecutive messages
  51           which are totally the same.
  52
  53 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  54         bool "Circular Buffer support"
  55         default y
  56         depends on BUSYBOX_CONFIG_SYSLOGD
  57         help
  58           When you enable this feature, the syslogd utility will
  59           use a circular buffer to record system log messages.
  60           When the buffer is filled it will continue to overwrite
  61           the oldest messages. This can be very useful for
  62           systems with little or no permanent storage, since
  63           otherwise system logs can eventually fill up your
  64           entire filesystem, which may cause your system to
  65           break badly.
  66
  67 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE
  68         int "Circular buffer size in Kbytes (minimum 4KB)"
  69         default 16
  70         range 4 2147483647
  71         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  72         help
  73           This option sets the size of the circular buffer
  74           used to record system log messages.
  75
  76 config BUSYBOX_CONFIG_LOGREAD
  77         bool "logread"
  78         default y
  79         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  80         help
  81           If you enabled Circular Buffer support, you almost
  82           certainly want to enable this feature as well. This
  83           utility will allow you to read the messages that are
  84           stored in the syslogd circular buffer.
  85
  86 config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
  87         bool "Double buffering"
  88         default n
  89         depends on BUSYBOX_CONFIG_LOGREAD
  90         help
  91           'logread' ouput to slow serial terminals can have
  92           side effects on syslog because of the semaphore.
  93           This option make logread to double buffer copy
  94           from circular buffer, minimizing semaphore
  95           contention at some minor memory expense.
  96
  97 config BUSYBOX_CONFIG_KLOGD
  98         bool "klogd"
  99         default y
 100         help
 101           klogd is a utility which intercepts and logs all
 102           messages from the Linux kernel and sends the messages
 103           out to the 'syslogd' utility so they can be logged. If
 104           you wish to record the messages produced by the kernel,
 105           you should enable this option.
 106
 107 config BUSYBOX_CONFIG_LOGGER
 108         bool "logger"
 109         default y
 110         select BUSYBOX_CONFIG_FEATURE_SYSLOG
 111         help
 112             The logger utility allows you to send arbitrary text
 113             messages to the system log (i.e. the 'syslogd' utility) so
 114             they can be logged. This is generally used to help locate
 115             problems that occur within programs and scripts.
