Linux log analyzer
Every Linux system has multiple log files that store important events that happen on the device or network. Some of the most important files are:
- /var/log/auth.log - Stores the status of all authentication attempts, whether successful or not.
- /var/log/wtmp.log - Stores all login, logout, and reboot information.
- /var/log/lastlog.log - Stores the details of the last time each user on the system logged in.
You can manually analyze Linux logs by using a few commands to get the information you need in the bash command line. Some of the commands are:
- cd /var/log/ - Changes working directory to the folder mentioned.
- head -n 20 ex.log - Displays the first 20 lines of the file.
- tail -n 20 ex..log - Displays the last 20 lines of the file.
- grep "changed" ex.log (most used) - Searches for the string "changed" within the ex.log file and prints the lines that contain the string.
You can also take it one step further and use Python to create tools to automate and simplify log analysis.
Challenges in manual analysis
- It's a pretty boring and unnecessary job to do when you have a lot of other important things on your plate.
- It's easy to miss the important stuff.
- As your organization scales up, it can become difficult to manage the logs generated from hundreds of devices in the network.
- You can't know what's right or wrong at a glance due to the lack of visualization.
