know where the log files are located, and what is contained in each and every log file. When your
systems are running smoothly, take some time to learn and understand the /var/log/syslog content of various log files, which will help you when there is a crisis and you have to look
though the log files to identify the issue. /etc/rsyslog.conf controls what goes inside some of the log files. For example, following is the entry in rsyslog.conf for /var/log/messages. $ grep http://www.cyberciti.biz/faq/linux-log-files-location-and-how-do-i-view-logs-files/ "/var/log/messages" /etc/rsyslog.conf *.info;mail.none;authpriv.none;cron.none /var/log/messages In the above output, *.info indicates that all logs with type INFO will be logged. mail.none,authpriv.none,cron.none indicates that those error messages should not be logged into the /var/log/messages file. You can also specify *.none, which indicates that none of the log messages will be logged. The following are the 20 different log files that are located http://www.thegeekstuff.com/2011/08/linux-var-log-files/ under /var/log/ directory. Some of these log files are distribution specific. For example, you'll see dpkg.log on Debian based systems (for example, on Ubuntu). /var/log/messages - Contains global system messages, including the messages that are logged during system startup. There are several things that are logged in /var/log/messages including mail, cron, daemon, kern, auth, etc. /var/log/dmesg - Contains kernel ring buffer information. When the system boots up, it prints number of messages on the screen that displays information about the hardware devices that the kernel detects during boot process. These messages are available in kernel ring buffer and whenever the new message comes the old message gets overwritten. You can also view the content of this file using the dmesg command. /var/log/auth.log - Contains system authorization information, including user logins and authentication machinsm that were used. /var/log/boot.log - Contains information that are logged when the system boots /var/log/daemon.log - Contains information logged by the various background daemons that runs on the system /var/log/dpkg.log - Contains information that are logged when a package is installed or removed using dpkg command /var
kernel, services, and applications running on it. There are different log files for different information. For https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/3/html/System_Administration_Guide/ch-logfiles.html example, there is a default system log file, a log file just for security messages, and a log file for cron tasks.Log http://www.faqforge.com/linux/distributions/debian/linux-how-to-view-log-files-on-the-shell/ files can be very useful when trying to troubleshoot a problem with the system such as trying to load a kernel driver or when looking for log file unauthorized log in attempts to the system. This chapter discusses where to find log files, how to view log files, and what to look for in log files. Some log files are controlled by a daemon called syslogd. A list of log messages maintained by syslogd can logs in linux be found in the /etc/syslog.conf configuration file. 38.1. Locating Log Files Most log files are located in the /var/log/ directory. Some applications such as httpd and samba have a directory within /var/log/ for their log files. Notice the multiple files in the log file directory with numbers after them. These are created when the log files are rotated. Log files are rotated so their file sizes do not become too large. The logrotate package contains a cron task that automatically rotates log files according to the /etc/logrotate.conf configuration file and the configuration files in the /etc/logrotate.d/ directory. By default, it is configured to rotate every week and keep four weeks worth of previous log files.
