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 http://www.thegeekstuff.com/2011/08/linux-var-log-files/ time to learn and understand the content of various log files, which will help https://www.digitalocean.com/community/tutorials/how-to-view-and-configure-linux-logs-on-ubuntu-and-centos 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 "/var/log/messages" /etc/rsyslog.conf *.info;mail.none;authpriv.none;cron.none /var/log/messages In the above output, *.info indicates that all how to 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 under /var/log/ directory. Some of these log files are distribution specific. For example, you'll see dpkg.log on Debian logs in linux 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/log/kern.log - Contains information logged by the kernel. Helpful for you to troubleshoot a custom-built kernel. /var/log/lastlog - Displays the recent login information for all the users. This is not an ascii file. You should use la

In fact, this is the first thing any sysadmin would do. Linux and the applications that run on it can generate all different types of messages, which are recorded in various log files. Linux uses a set of configuration files, directories, programs, commands and daemons to create, store and recycle these log messages. Knowing where the system keeps its log files and how to make use of related commands can therefore help save valuable time during troubleshooting. In this tutorial, we will have a look at different parts of the Linux logging mechanism. Disclaimer The commands in this tutorial were tested in plain vanilla installations of CentOS 6.4, Ubuntu 12 and Debian 7. Default Log File Location The default location for log files in Linux is /var/log. You can view the list of log files in this directory with a simple ls -l /var/log command. This is what I see in my CentOS system: [root@TestLinux ~]# ls -l /var/log total 1472 -rw-------. 1 root root 4524 Nov 15 16:04 anaconda.ifcfg.log -rw-------. 1 root root 59041 Nov 15 16:04 anaconda.log -rw-------. 1 root root 42763 Nov 15 16:04 anaconda.program.log -rw-------. 1 root root 299910 Nov 15 16:04 anaconda.storage.log -rw-------. 1 root root 40669 Nov 15 16:04 anaconda.syslog -rw-------. 1 root root 57061 Nov 15 16:04 anaconda.xlog -rw-------. 1 root root
