Real-time log inspection

Inspector General

The End Is Nigh

As you have seen, Teler is a highly useful addition to any security toolbox. If you want to experiment with real-time log scanning – as opposed to reading from saved logfiles – then the docs point you to stdbuf [8], which is a command to pull in data in a stream:

$ tail -f access.log | stdbuf -oL cut -d aq aq -f1 | uniq

With the tail command, it is possible to format the entries into a useful layout that scripts and other applications can use.

I will be keeping an eye on Teler as new features and supported formats are developed in later versions.
