11 config BUSYBOX_CONFIG_SYSLOGD
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....
26 config BUSYBOX_CONFIG_FEATURE_ROTATE_LOGFILE
27 bool "Rotate message files"
29 depends on BUSYBOX_CONFIG_SYSLOGD
31 This enables syslogd to rotate the message files
32 on his own. No need to use an external rotatescript.
34 config BUSYBOX_CONFIG_FEATURE_REMOTE_LOG
35 bool "Remote Log support"
37 depends on BUSYBOX_CONFIG_SYSLOGD
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
48 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_DUP
49 bool "Support -D (drop dups) option"
51 depends on BUSYBOX_CONFIG_SYSLOGD
53 Option -D instructs syslogd to drop consecutive messages
54 which are totally the same.
56 config BUSYBOX_CONFIG_FEATURE_SYSLOGD_READ_BUFFER_SIZE
57 int "Read buffer size in bytes"
60 depends on BUSYBOX_CONFIG_SYSLOGD
62 This option sets the size of the syslog read buffer.
63 Actual memory usage increases around five times the
66 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
67 bool "Circular Buffer support"
69 depends on BUSYBOX_CONFIG_SYSLOGD
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
80 config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE
81 int "Circular buffer size in Kbytes (minimum 4KB)"
84 depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
86 This option sets the size of the circular buffer
87 used to record system log messages.
89 config BUSYBOX_CONFIG_LOGREAD
92 depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
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.
99 config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
100 bool "Double buffering"
102 depends on BUSYBOX_CONFIG_LOGREAD
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.
110 config BUSYBOX_CONFIG_KLOGD
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.
120 config BUSYBOX_CONFIG_FEATURE_KLOGD_KLOGCTL
121 bool "Use the klogctl() interface"
123 depends on BUSYBOX_CONFIG_KLOGD && BUSYBOX_CONFIG_PLATFORM_LINUX
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.
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.
134 If in doubt, say 'Y'.
136 config BUSYBOX_CONFIG_LOGGER
139 select BUSYBOX_CONFIG_FEATURE_SYSLOG
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.
