Every message that is logged records the date and time of the event, and will generally also record the name of the application that generated the message. When used in conjunction with klogd, messages from the Linux kernel can also be recorded. This is terribly useful, especially for finding what happened when something goes wrong. And something almost always will go wrong if you wait long enough.... config BUSYBOX_CONFIG_FEATURE_ROTATE_LOGFILE bool "Rotate message files" default y depends on BUSYBOX_CONFIG_SYSLOGD help This enables syslogd to rotate the message files on his own. No need to use an external rotatescript. config BUSYBOX_CONFIG_FEATURE_REMOTE_LOG bool "Remote Log support" default y depends on BUSYBOX_CONFIG_SYSLOGD help When you enable this feature, the syslogd utility can be used to send system log messages to another system connected via a network. This allows the remote machine to log all the system messages, which can be terribly useful for reducing the number of serial cables you use. It can also be a very good security measure to prevent system logs from being tampered with by an intruder. config BUSYBOX_CONFIG_FEATURE_SYSLOGD_DUP bool "Support -D (drop dups) option" default n depends on BUSYBOX_CONFIG_SYSLOGD help Option -D instructs syslogd to drop consecutive messages which are totally the same. config BUSYBOX_CONFIG_FEATURE_SYSLOGD_READ_BUFFER_SIZE int "Read buffer size in bytes" default 256 range 256 20000 depends on BUSYBOX_CONFIG_SYSLOGD help This option sets the size of the syslog read buffer. Actual memory usage increases around five times the change done here. config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG bool "Circular Buffer support" default y depends on BUSYBOX_CONFIG_SYSLOGD help When you enable this feature, the syslogd utility will use a circular buffer to record system log messages. When the buffer is filled it will continue to overwrite the oldest messages. This can be very useful for systems with little or no permanent storage, since otherwise system logs can eventually fill up your entire filesystem, which may cause your system to break badly. config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE int "Circular buffer size in Kbytes (minimum 4KB)" default 16 range 4 2147483647 depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG help This option sets the size of the circular buffer used to record system log messages. config BUSYBOX_CONFIG_LOGREAD bool "logread" default y depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG help If you enabled Circular Buffer support, you almost certainly want to enable this feature as well. This utility will allow you to read the messages that are stored in the syslogd circular buffer. config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING bool "Double buffering" default n depends on BUSYBOX_CONFIG_LOGREAD help 'logread' ouput to slow serial terminals can have side effects on syslog because of the semaphore. This option make logread to double buffer copy from circular buffer, minimizing semaphore contention at some minor memory expense. config BUSYBOX_CONFIG_KLOGD bool "klogd" default y help klogd is a utility which intercepts and logs all messages from the Linux kernel and sends the messages out to the 'syslogd' utility so they can be logged. If you wish to record the messages produced by the kernel, you should enable this option. config BUSYBOX_CONFIG_FEATURE_KLOGD_KLOGCTL bool "Use the klogctl() interface" default y depends on BUSYBOX_CONFIG_KLOGD && BUSYBOX_CONFIG_PLATFORM_LINUX help The klogd applet supports two interfaces for reading kernel messages. Linux provides the klogctl() interface which allows reading messages from the kernel ring buffer independently from the file system. If you answer 'N' here, klogd will use the more portable approach of reading them from /proc or a device node. However, this method requires the file to be available. If in doubt, say 'Y'. config BUSYBOX_CONFIG_LOGGER bool "logger" default y select BUSYBOX_CONFIG_FEATURE_SYSLOG help The logger utility allows you to send arbitrary text messages to the system log (i.e. the 'syslogd' utility) so they can be logged. This is generally used to help locate problems that occur within programs and scripts. endmenu f='#n45'>45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318
