  12         help
  13         klogd is a utility which intercepts and logs all
  14         messages from the Linux kernel and sends the messages
  15         out to the 'syslogd' utility so they can be logged. If
  16         you wish to record the messages produced by the kernel,
  17         you should enable this option.

  22 config BUSYBOX_CONFIG_FEATURE_KLOGD_KLOGCTL
  23         bool "Use the klogctl() interface"
  24         default BUSYBOX_DEFAULT_FEATURE_KLOGD_KLOGCTL
  25         depends on BUSYBOX_CONFIG_KLOGD
  26         select BUSYBOX_CONFIG_PLATFORM_LINUX
  27         help
  28         The klogd applet supports two interfaces for reading
  29         kernel messages. Linux provides the klogctl() interface
  30         which allows reading messages from the kernel ring buffer
  31         independently from the file system.
  32
  33         If you answer 'N' here, klogd will use the more portable
  34         approach of reading them from /proc or a device node.
  35         However, this method requires the file to be available.
  36
  37         If in doubt, say 'Y'.
  38 config BUSYBOX_CONFIG_LOGGER
  39         bool "logger (6.3 kb)"
  40         default BUSYBOX_DEFAULT_LOGGER
  41         select BUSYBOX_CONFIG_FEATURE_SYSLOG
  42         help
  43         The logger utility allows you to send arbitrary text
  44         messages to the system log (i.e. the 'syslogd' utility) so
  45         they can be logged. This is generally used to help locate
  46         problems that occur within programs and scripts.
  47 config BUSYBOX_CONFIG_LOGREAD
  48         bool "logread (4.8 kb)"
  49         default BUSYBOX_DEFAULT_LOGREAD
  50         help
  51         If you enabled Circular Buffer support, you almost
  52         certainly want to enable this feature as well. This
  53         utility will allow you to read the messages that are
  54         stored in the syslogd circular buffer.
  55
  56 config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
  57         bool "Double buffering"
  58         default BUSYBOX_DEFAULT_FEATURE_LOGREAD_REDUCED_LOCKING
  59         depends on BUSYBOX_CONFIG_LOGREAD
  60         help
  61         'logread' output to slow serial terminals can have
  62         side effects on syslog because of the semaphore.
  63         This option make logread to double buffer copy
  64         from circular buffer, minimizing semaphore
  65         contention at some minor memory expense.
  66
  67 config BUSYBOX_CONFIG_SYSLOGD
  68         bool "syslogd (13 kb)"
  69         default BUSYBOX_DEFAULT_SYSLOGD
  70         help
  71         The syslogd utility is used to record logs of all the
  72         significant events that occur on a system. Every
  73         message that is logged records the date and time of the
  74         event, and will generally also record the name of the
  75         application that generated the message. When used in
  76         conjunction with klogd, messages from the Linux kernel
  77         can also be recorded. This is terribly useful,
  78         especially for finding what happened when something goes
  79         wrong. And something almost always will go wrong if
  80         you wait long enough....
  81
  82 config BUSYBOX_CONFIG_FEATURE_ROTATE_LOGFILE
  83         bool "Rotate message files"
  84         default BUSYBOX_DEFAULT_FEATURE_ROTATE_LOGFILE
  85         depends on BUSYBOX_CONFIG_SYSLOGD
  86         help
  87         This enables syslogd to rotate the message files
  88         on his own. No need to use an external rotate script.
  89
  90 config BUSYBOX_CONFIG_FEATURE_REMOTE_LOG
  91         bool "Remote Log support"
  92         default BUSYBOX_DEFAULT_FEATURE_REMOTE_LOG
  93         depends on BUSYBOX_CONFIG_SYSLOGD
  94         help
  95         When you enable this feature, the syslogd utility can
  96         be used to send system log messages to another system
  97         connected via a network. This allows the remote
  98         machine to log all the system messages, which can be
  99         terribly useful for reducing the number of serial
 100         cables you use. It can also be a very good security
 101         measure to prevent system logs from being tampered with
 102         by an intruder.
 103
 104 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_DUP
 105         bool "Support -D (drop dups) option"
 106         default BUSYBOX_DEFAULT_FEATURE_SYSLOGD_DUP
 107         depends on BUSYBOX_CONFIG_SYSLOGD
 108         help
 109         Option -D instructs syslogd to drop consecutive messages
 110         which are totally the same.
 111
 112 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_CFG
 113         bool "Support syslog.conf"

 115         depends on BUSYBOX_CONFIG_SYSLOGD
 116         help
 117         Supports restricted syslogd config. See docs/syslog.conf.txt
 118
 119 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_READ_BUFFER_SIZE

 122         range 256 20000
 123         depends on BUSYBOX_CONFIG_SYSLOGD
 124         help
 125         This option sets the size of the syslog read buffer.
 126         Actual memory usage increases around five times the
 127         change done here.
 128
 129 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
 130         bool "Circular Buffer support"
 131         default BUSYBOX_DEFAULT_FEATURE_IPC_SYSLOG
 132         depends on BUSYBOX_CONFIG_SYSLOGD
 133         help
 134         When you enable this feature, the syslogd utility will
 135         use a circular buffer to record system log messages.
 136         When the buffer is filled it will continue to overwrite
 137         the oldest messages. This can be very useful for
 138         systems with little or no permanent storage, since
 139         otherwise system logs can eventually fill up your
 140         entire filesystem, which may cause your system to
 141         break badly.
 142
 143 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE
 144         int "Circular buffer size in Kbytes (minimum 4KB)"
 145         default BUSYBOX_DEFAULT_FEATURE_IPC_SYSLOG_BUFFER_SIZE

 147         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
 148         help
 149         This option sets the size of the circular buffer
 150         used to record system log messages.
 151
 152 config BUSYBOX_CONFIG_FEATURE_KMSG_SYSLOG
 153         bool "Linux kernel printk buffer support"
 154         default BUSYBOX_DEFAULT_FEATURE_KMSG_SYSLOG
 155         depends on BUSYBOX_CONFIG_SYSLOGD
 156         select BUSYBOX_CONFIG_PLATFORM_LINUX
 157         help
 158         When you enable this feature, the syslogd utility will
 159         write system log message to the Linux kernel's printk buffer.
 160         This can be used as a smaller alternative to the syslogd IPC
 161         support, as klogd and logread aren't needed.

 163         NOTICE: Syslog facilities in log entries needs kernel 3.5+.
