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

  26 config BUSYBOX_CONFIG_FEATURE_ROTATE_LOGFILE
  27         bool "Rotate message files"
  28         default y
  29         depends on BUSYBOX_CONFIG_SYSLOGD
  30         help
  31           This enables syslogd to rotate the message files
  32           on his own. No need to use an external rotatescript.
  33
  34 config BUSYBOX_CONFIG_FEATURE_REMOTE_LOG
  35         bool "Remote Log support"
  36         default y
  37         depends on BUSYBOX_CONFIG_SYSLOGD
  38         help
  39           When you enable this feature, the syslogd utility can
  40           be used to send system log messages to another system
  41           connected via a network. This allows the remote
  42           machine to log all the system messages, which can be
  43           terribly useful for reducing the number of serial
  44           cables you use. It can also be a very good security
  45           measure to prevent system logs from being tampered with
  46           by an intruder.
  47
  48 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_DUP
  49         bool "Support -D (drop dups) option"
  50         default n
  51         depends on BUSYBOX_CONFIG_SYSLOGD
  52         help
  53           Option -D instructs syslogd to drop consecutive messages
  54           which are totally the same.
  55
  56 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_CFG
  57         bool "Support syslog.conf"
  58         default n
  59         depends on BUSYBOX_CONFIG_SYSLOGD
  60         help
  61           Supports restricted syslogd config. See docs/syslog.conf.txt
  62
  63 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_READ_BUFFER_SIZE
  64         int "Read buffer size in bytes"
  65         default 256
  66         range 256 20000
  67         depends on BUSYBOX_CONFIG_SYSLOGD
  68         help
  69           This option sets the size of the syslog read buffer.
  70           Actual memory usage increases around five times the
  71           change done here.
  72
  73 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  74         bool "Circular Buffer support"
  75         default y
  76         depends on BUSYBOX_CONFIG_SYSLOGD
  77         help
  78           When you enable this feature, the syslogd utility will
  79           use a circular buffer to record system log messages.
  80           When the buffer is filled it will continue to overwrite
  81           the oldest messages. This can be very useful for
  82           systems with little or no permanent storage, since
  83           otherwise system logs can eventually fill up your
  84           entire filesystem, which may cause your system to
  85           break badly.
  86
  87 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE
  88         int "Circular buffer size in Kbytes (minimum 4KB)"
  89         default 16
  90         range 4 2147483647
  91         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  92         help
  93           This option sets the size of the circular buffer
  94           used to record system log messages.
  95
  96 config BUSYBOX_CONFIG_LOGREAD
  97         bool "logread"
  98         default y
  99         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
 100         help
 101           If you enabled Circular Buffer support, you almost
 102           certainly want to enable this feature as well. This
 103           utility will allow you to read the messages that are
 104           stored in the syslogd circular buffer.
 105
 106 config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
 107         bool "Double buffering"
 108         default n
 109         depends on BUSYBOX_CONFIG_LOGREAD
 110         help
 111           'logread' ouput to slow serial terminals can have
 112           side effects on syslog because of the semaphore.
 113           This option make logread to double buffer copy
 114           from circular buffer, minimizing semaphore
 115           contention at some minor memory expense.
 116
 117 config BUSYBOX_CONFIG_KLOGD
 118         bool "klogd"
 119         default y
 120         help
 121           klogd is a utility which intercepts and logs all
 122           messages from the Linux kernel and sends the messages
 123           out to the 'syslogd' utility so they can be logged. If
 124           you wish to record the messages produced by the kernel,
 125           you should enable this option.
 126
 127 config BUSYBOX_CONFIG_FEATURE_KLOGD_KLOGCTL
 128         bool "Use the klogctl() interface"
 129         default y
 130         depends on BUSYBOX_CONFIG_KLOGD
 131         select BUSYBOX_CONFIG_PLATFORM_LINUX
 132         help
 133           The klogd applet supports two interfaces for reading
 134           kernel messages. Linux provides the klogctl() interface
 135           which allows reading messages from the kernel ring buffer
 136           independently from the file system.
 137
 138           If you answer 'N' here, klogd will use the more portable
 139           approach of reading them from /proc or a device node.
 140           However, this method requires the file to be available.
 141
 142           If in doubt, say 'Y'.
 143
 144 config BUSYBOX_CONFIG_LOGGER
 145         bool "logger"
 146         default y
 147         select BUSYBOX_CONFIG_FEATURE_SYSLOG
 148         help
 149             The logger utility allows you to send arbitrary text
 150             messages to the system log (i.e. the 'syslogd' utility) so
 151             they can be logged. This is generally used to help locate
 152             problems that occur within programs and scripts.
