# # For a description of the syntax of this configuration file, # see scripts/kbuild/config-language.txt. # menu "System Logging Utilities" config CONFIG_SYSLOGD bool "syslogd" default n help The syslogd utility is used to record logs of all the significant events that occur on a system. 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 CONFIG_FEATURE_ROTATE_LOGFILE bool "Rotate message files" default n depends on CONFIG_SYSLOGD help This enables syslogd to rotate the message files on his own. No need to use an external rotatescript. config CONFIG_FEATURE_REMOTE_LOG bool "Remote Log support" default n depends on 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 CONFIG_FEATURE_IPC_SYSLOG bool "Circular Buffer support" default n depends on 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 CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE int " Circular buffer size in Kbytes (minimum 4KB)" default 16 depends on CONFIG_FEATURE_IPC_SYSLOG help This option sets the size of the circular buffer used to record system log messages. config CONFIG_LOGREAD bool "logread" default y depends on 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 CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING bool "logread double buffering" default n depends on 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 CONFIG_KLOGD bool "klogd" default n depends on CONFIG_SYSLOGD 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 CONFIG_LOGGER bool "logger" default n 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
