8 config BUSYBOX_CONFIG_SYSLOGD
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....
23 config BUSYBOX_CONFIG_FEATURE_ROTATE_LOGFILE
24 bool "Rotate message files"
26 depends on BUSYBOX_CONFIG_SYSLOGD
28 This enables syslogd to rotate the message files
29 on his own. No need to use an external rotatescript.
31 config BUSYBOX_CONFIG_FEATURE_REMOTE_LOG
32 bool "Remote Log support"
34 depends on BUSYBOX_CONFIG_SYSLOGD
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
45 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
46 bool "Circular Buffer support"
48 depends on BUSYBOX_CONFIG_SYSLOGD
50 When you enable this feature, the syslogd utility will
51 use a circular buffer to record system log messages.
52 When the buffer is filled it will continue to overwrite
53 the oldest messages. This can be very useful for
54 systems with little or no permanent storage, since
55 otherwise system logs can eventually fill up your
56 entire filesystem, which may cause your system to
59 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE
60 int " Circular buffer size in Kbytes (minimum 4KB)"
62 depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
64 This option sets the size of the circular buffer
65 used to record system log messages.
67 config BUSYBOX_CONFIG_LOGREAD
70 depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
72 If you enabled Circular Buffer support, you almost
73 certainly want to enable this feature as well. This
74 utility will allow you to read the messages that are
75 stored in the syslogd circular buffer.
77 config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
78 bool "logread double buffering"
80 depends on BUSYBOX_CONFIG_LOGREAD
82 'logread' ouput to slow serial terminals can have
83 side effects on syslog because of the semaphore.
84 This option make logread to double buffer copy
85 from circular buffer, minimizing semaphore
86 contention at some minor memory expense.
88 config BUSYBOX_CONFIG_KLOGD
91 depends on BUSYBOX_CONFIG_SYSLOGD
92 select BUSYBOX_CONFIG_FEATURE_SYSLOG
94 klogd is a utility which intercepts and logs all
95 messages from the Linux kernel and sends the messages
96 out to the 'syslogd' utility so they can be logged. If
97 you wish to record the messages produced by the kernel,
98 you should enable this option.
100 config BUSYBOX_CONFIG_LOGGER
103 select BUSYBOX_CONFIG_FEATURE_SYSLOG
105 The logger utility allows you to send arbitrary text
106 messages to the system log (i.e. the 'syslogd' utility) so
107 they can be logged. This is generally used to help locate
108 problems that occur within programs and scripts.
