8config 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
23config 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
31config 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
45config 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
53config 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
67config 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
76config 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
86config 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
97config 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
107config 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.
