Log Files in GNU/Linux
Log Files in GNU/Linux
GNU/Linux is a very flexible operating system. One of its major plus points is that everything that happens when the system is running is logged somewhere. If anything malfunctions, error messages are dumped to log files for use by the system administrator. Log files are very helpful in troubleshooting and fixing errors.
Log files are very advantageous. They contain information about various aspects of the computer. If some of the hardware is functioning properly, log files provide the exact information about where it is failing. Logging daemons also keep track about users accessing the computer. If someone succeeds in intruding a Linux system, the details of the intrusion can be found out by going through the log files.
Usually in Linux, logging is handled by two daemons–syslogd and klogd. Syslogd performs general system logging. Klogd performs kernel level logging.
In Linux, the syslog.conf file which is located in the /etc directory controls the various aspects of logging. Log files are located in /var/log/ directory.
Here are the usual log files:
= boot.log: Contains messages about system/application startup.
= messages: Contains messages relating to the system i.e. OS
= secure: Contains security related messages. For example. details about user logging.
= Free86.0.log, Xorg.0.log: Contain messages related to video configuration and mouse. Depending on the type of X server you have installed on your Linux system, you will find either of the file mentioned here.
Popular distrubutions may come with utilities of viewing log files. For example, Fedora Core Linux comes with System Log Viewer, a utility that allows the user to view logsabout mail, the kernel, security datewise.
Heavyload–Test your computer’s endurance
Heavyload is a free program that offers an interesting way to test your computer’s endurance. Heavyload is a free application that allows the user to assess the endurance of his/her computer.
By pushing your system to the limit, Heavyload will show you how well your PC can handle stress. Heavyload will test the system and determine how well it can handle computing stress. In other words, the software will push the computer to its limits.
The program’s interface is cut down to the basics, which makes it easy to navigate. Heavyload comes with a simple user interface. This makes the software very easy to use.While it only has a few command icons, they’re well labeled, and they’re all that you need to conduct a successful test.
The software comes with few icons, however, these are properly labelled and so it is very easy to use the software. The program’s running graph shows your available memory and CPU usage, which comes in handy when using some of Heavyload’s other features.
The app will show the amount of RAM available and CPU usage in a graphical form. There are four different testing options, though the program does a poor job of differentiating them, so we left the default settings in place.
There are four different testing modes. However, it is advisable to stick to the default settings as that does the job done perfectly. Luckily, too, since our CPU usage chart instantly began to skyrocket. By quickly filling your RAM, hard disk, and operating system with test data,
Heavyload offers an easy and safe way to simulate conditions that could cause your computer to overheat or crash. Heavyload is freeware. It comes as a compressed file. This program is practical and simple to operate, and we recommend it.
