How do you audit your Linux environment? How do you track after changes to your files? What kind of processes are running on your system at any given moment? What uses the most resources? Valid questions, all. Special contributor Dedoimedo gives us the straight scoop on “audit.”. We’ve monitored system activity with sar. We used iostat, vmstat and dstat to collect statistics on resource usage. We learned about pacct for process accounting. We also worked with top in batch mode and atop. Finally, we worked with some high-end debugging tools like OProfile and strace. Links below. But we did not use any utility for file auditing.
Today, we do that. The name of the game: Linux audit.
