  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....
  25
  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_READ_BUFFER_SIZE
  57         int "Read buffer size in bytes"
  58         default 256
  59         range 256 20000
  60         depends on BUSYBOX_CONFIG_SYSLOGD
  61         help
  62           This option sets the size of the syslog read buffer.
  63           Actual memory usage increases around five times the
  64           change done here.
  65
  66 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  67         bool "Circular Buffer support"
  68         default y
  69         depends on BUSYBOX_CONFIG_SYSLOGD
  70         help
  71           When you enable this feature, the syslogd utility will
  72           use a circular buffer to record system log messages.
  73           When the buffer is filled it will continue to overwrite
  74           the oldest messages. This can be very useful for
  75           systems with little or no permanent storage, since
  76           otherwise system logs can eventually fill up your
  77           entire filesystem, which may cause your system to
  78           break badly.
  79
  80 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE
  81         int "Circular buffer size in Kbytes (minimum 4KB)"
  82         default 16
  83         range 4 2147483647
  84         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  85         help
  86           This option sets the size of the circular buffer
  87           used to record system log messages.
  88
  89 config BUSYBOX_CONFIG_LOGREAD
  90         bool "logread"
  91         default y
  92         depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
  93         help
  94           If you enabled Circular Buffer support, you almost
  95           certainly want to enable this feature as well. This
  96           utility will allow you to read the messages that are
  97           stored in the syslogd circular buffer.
  98
  99 config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
 100         bool "Double buffering"
 101         default n
 102         depends on BUSYBOX_CONFIG_LOGREAD
 103         help
 104           'logread' ouput to slow serial terminals can have
 105           side effects on syslog because of the semaphore.
 106           This option make logread to double buffer copy
 107           from circular buffer, minimizing semaphore
 108           contention at some minor memory expense.
 109
 110 config BUSYBOX_CONFIG_KLOGD
 111         bool "klogd"
 112         default y
 113         help
 114           klogd is a utility which intercepts and logs all
 115           messages from the Linux kernel and sends the messages
 116           out to the 'syslogd' utility so they can be logged. If
 117           you wish to record the messages produced by the kernel,
 118           you should enable this option.
 119
 120 config BUSYBOX_CONFIG_FEATURE_KLOGD_KLOGCTL
 121         bool "Use the klogctl() interface"
 122         default y
 123         depends on BUSYBOX_CONFIG_KLOGD && BUSYBOX_CONFIG_PLATFORM_LINUX
 124         help
 125           The klogd applet supports two interfaces for reading
 126           kernel messages. Linux provides the klogctl() interface
 127           which allows reading messages from the kernel ring buffer
 128           independently from the file system.
 129
 130           If you answer 'N' here, klogd will use the more portable
 131           approach of reading them from /proc or a device node.
 132           However, this method requires the file to be available.
 133
 134           If in doubt, say 'Y'.
 135
 136 config BUSYBOX_CONFIG_LOGGER
 137         bool "logger"
 138         default y
 139         select BUSYBOX_CONFIG_FEATURE_SYSLOG
 140         help
 141             The logger utility allows you to send arbitrary text
 142             messages to the system log (i.e. the 'syslogd' utility) so
 143             they can be logged. This is generally used to help locate
 144             problems that occur within programs and scripts.
