  10         bool "klogd (5.7 kb)"
  11         default BUSYBOX_DEFAULT_KLOGD
  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         help
  27         The klogd applet supports two interfaces for reading
  28         kernel messages. Linux provides the klogctl() interface
  29         which allows reading messages from the kernel ring buffer
  30         independently from the file system.
  31
  32         If you answer 'N' here, klogd will use the more portable
  33         approach of reading them from /proc or a device node.
  34         However, this method requires the file to be available.
  35
  36         If in doubt, say 'Y'.
  37 config BUSYBOX_CONFIG_LOGGER
  38         bool "logger (6.3 kb)"
  39         default BUSYBOX_DEFAULT_LOGGER
  40         select BUSYBOX_CONFIG_FEATURE_SYSLOG
  41         help
  42         The logger utility allows you to send arbitrary text
  43         messages to the system log (i.e. the 'syslogd' utility) so
  44         they can be logged. This is generally used to help locate
  45         problems that occur within programs and scripts.
  46 config BUSYBOX_CONFIG_LOGREAD
  47         bool "logread (4.8 kb)"
  48         default BUSYBOX_DEFAULT_LOGREAD
  49         help
  50         If you enabled Circular Buffer support, you almost
  51         certainly want to enable this feature as well. This
  52         utility will allow you to read the messages that are
  53         stored in the syslogd circular buffer.
  54
  55 config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
  56         bool "Double buffering"
  57         default BUSYBOX_DEFAULT_FEATURE_LOGREAD_REDUCED_LOCKING
  58         depends on BUSYBOX_CONFIG_LOGREAD
  59         help
  60         'logread' output to slow serial terminals can have
  61         side effects on syslog because of the semaphore.
  62         This option make logread to double buffer copy
  63         from circular buffer, minimizing semaphore
  64         contention at some minor memory expense.
  65
  66 config BUSYBOX_CONFIG_SYSLOGD
  67         bool "syslogd (13 kb)"
  68         default BUSYBOX_DEFAULT_SYSLOGD
  69         help
  70         The syslogd utility is used to record logs of all the
  71         significant events that occur on a system. Every
  72         message that is logged records the date and time of the
  73         event, and will generally also record the name of the
  74         application that generated the message. When used in
  75         conjunction with klogd, messages from the Linux kernel
  76         can also be recorded. This is terribly useful,
  77         especially for finding what happened when something goes
  78         wrong. And something almost always will go wrong if
  79         you wait long enough....
  80
  81 config BUSYBOX_CONFIG_FEATURE_ROTATE_LOGFILE
  82         bool "Rotate message files"
  83         default BUSYBOX_DEFAULT_FEATURE_ROTATE_LOGFILE
  84         depends on BUSYBOX_CONFIG_SYSLOGD
  85         help
  86         This enables syslogd to rotate the message files
  87         on his own. No need to use an external rotate script.
  88
  89 config BUSYBOX_CONFIG_FEATURE_REMOTE_LOG
  90         bool "Remote Log support"
  91         default BUSYBOX_DEFAULT_FEATURE_REMOTE_LOG
  92         depends on BUSYBOX_CONFIG_SYSLOGD
  93         help
  94         When you enable this feature, the syslogd utility can
  95         be used to send system log messages to another system
  96         connected via a network. This allows the remote
  97         machine to log all the system messages, which can be
  98         terribly useful for reducing the number of serial
  99         cables you use. It can also be a very good security
 100         measure to prevent system logs from being tampered with
 101         by an intruder.
 102
 103 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_DUP
 104         bool "Support -D (drop dups) option"
 105         default BUSYBOX_DEFAULT_FEATURE_SYSLOGD_DUP
 106         depends on BUSYBOX_CONFIG_SYSLOGD
 107         help
 108         Option -D instructs syslogd to drop consecutive messages
 109         which are totally the same.
 110
 111 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_CFG
 112         bool "Support syslog.conf"

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

 121         depends on BUSYBOX_CONFIG_SYSLOGD
 122         help
 123         Includes milliseconds (HH:MM:SS.mmm) in timestamp when
 124         timestamps are added.

 126 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_READ_BUFFER_SIZE
 127         int "Read buffer size in bytes"

 129         range 256 20000
 130         depends on BUSYBOX_CONFIG_SYSLOGD
 131         help
 132         This option sets the size of the syslog read buffer.
 133         Actual memory usage increases around five times the
 134         change done here.
 135
 136 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
 137         bool "Circular Buffer support"
 138         default BUSYBOX_DEFAULT_FEATURE_IPC_SYSLOG
 139         depends on BUSYBOX_CONFIG_SYSLOGD
 140         help
 141         When you enable this feature, the syslogd utility will
 142         use a circular buffer to record system log messages.
 143         When the buffer is filled it will continue to overwrite
 144         the oldest messages. This can be very useful for
 145         systems with little or no permanent storage, since
 146         otherwise system logs can eventually fill up your
 147         entire filesystem, which may cause your system to
 148         break badly.
 149
 150 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE

 154         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
 155         help
 156         This option sets the size of the circular buffer
 157         used to record system log messages.

 160         bool "Linux kernel printk buffer support"
 161         default BUSYBOX_DEFAULT_FEATURE_KMSG_SYSLOG
 162         depends on BUSYBOX_CONFIG_SYSLOGD
 163         help
 164         When you enable this feature, the syslogd utility will
 165         write system log message to the Linux kernel's printk buffer.
 166         This can be used as a smaller alternative to the syslogd IPC
 167         support, as klogd and logread aren't needed.

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