Linux is generating more logging than normal. Now what? Should I panic?
If the log settings of Linux are properly configured, tuned, and verified, all log files should be located in (a subfolder of) /var/log. Optionally and depending upon IT security policy it should also be sent to another location. As any other system administrator will do, it is best practice to monitor these files at regular intervals. Recently I’ve noticed a change in these log files. Some of them started to grow faster. Some of these troublesome files contain the logging of the firewall, therefore, is the question ‘Should I hit the panic button?’ somewhat justified. Let’s dive into this anomaly.
