10 bool "klogd"
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.

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"
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"
49 default BUSYBOX_DEFAULT_LOGREAD
50 depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
51 help
52 If you enabled Circular Buffer support, you almost
53 certainly want to enable this feature as well. This
54 utility will allow you to read the messages that are
55 stored in the syslogd circular buffer.
56
57 config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
58 bool "Double buffering"
59 default BUSYBOX_DEFAULT_FEATURE_LOGREAD_REDUCED_LOCKING
60 depends on BUSYBOX_CONFIG_LOGREAD
61 help
62 'logread' ouput to slow serial terminals can have
63 side effects on syslog because of the semaphore.
64 This option make logread to double buffer copy
65 from circular buffer, minimizing semaphore
66 contention at some minor memory expense.
67
68 config BUSYBOX_CONFIG_SYSLOGD
69 bool "syslogd"
70 default BUSYBOX_DEFAULT_SYSLOGD
71 help
72 The syslogd utility is used to record logs of all the
73 significant events that occur on a system. Every
74 message that is logged records the date and time of the
75 event, and will generally also record the name of the
76 application that generated the message. When used in
77 conjunction with klogd, messages from the Linux kernel
78 can also be recorded. This is terribly useful,
79 especially for finding what happened when something goes
80 wrong. And something almost always will go wrong if
81 you wait long enough....

83 config BUSYBOX_CONFIG_FEATURE_ROTATE_LOGFILE
84 bool "Rotate message files"
85 default BUSYBOX_DEFAULT_FEATURE_ROTATE_LOGFILE
86 depends on BUSYBOX_CONFIG_SYSLOGD
87 help
88 This enables syslogd to rotate the message files
89 on his own. No need to use an external rotate script.

91 config BUSYBOX_CONFIG_FEATURE_REMOTE_LOG
92 bool "Remote Log support"
93 default BUSYBOX_DEFAULT_FEATURE_REMOTE_LOG
94 depends on BUSYBOX_CONFIG_SYSLOGD
95 help
96 When you enable this feature, the syslogd utility can
97 be used to send system log messages to another system
98 connected via a network. This allows the remote
99 machine to log all the system messages, which can be
100 terribly useful for reducing the number of serial
101 cables you use. It can also be a very good security
102 measure to prevent system logs from being tampered with
103 by an intruder.
104
105 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_DUP
106 bool "Support -D (drop dups) option"
107 default BUSYBOX_DEFAULT_FEATURE_SYSLOGD_DUP
108 depends on BUSYBOX_CONFIG_SYSLOGD
109 help
110 Option -D instructs syslogd to drop consecutive messages
111 which are totally the same.

125 help
126 This option sets the size of the syslog read buffer.
127 Actual memory usage increases around five times the
128 change done here.

130 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
131 bool "Circular Buffer support"
132 default BUSYBOX_DEFAULT_FEATURE_IPC_SYSLOG
133 depends on BUSYBOX_CONFIG_SYSLOGD
134 help
135 When you enable this feature, the syslogd utility will
136 use a circular buffer to record system log messages.
137 When the buffer is filled it will continue to overwrite
138 the oldest messages. This can be very useful for
139 systems with little or no permanent storage, since
140 otherwise system logs can eventually fill up your
141 entire filesystem, which may cause your system to
142 break badly.

144 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE

155 default BUSYBOX_DEFAULT_FEATURE_KMSG_SYSLOG
156 depends on BUSYBOX_CONFIG_SYSLOGD
157 select BUSYBOX_CONFIG_PLATFORM_LINUX
158 help
159 When you enable this feature, the syslogd utility will
160 write system log message to the Linux kernel's printk buffer.
161 This can be used as a smaller alternative to the syslogd IPC
162 support, as klogd and logread aren't needed.
163
164 NOTICE: Syslog facilities in log entries needs kernel 3.5+.
