GUI for watching logs (tail and grep)

Question

Could you recommend a GUI application with powerful log watching capabilities?

Generally it would work as tail -f in GUI, but on top of that following features would be very useful:

filtering out some lines based on (regular) expressions
coloring some lines based on (regular) expressions
interactive search
saveable configuration easily applicable to different files
notifications based on (regular) expressions

A similar tool on Windows is BareTail and its paid version - BareTailPro

I've discovered glogg, which describes itself as:

glogg is a multi-platform GUI application to browse and search through long or complex log files. It is designed with programmers and system administrators in mind. glogg can be seen as a graphical, interactive combination of grep and less.

It will also tail files if you enable the Follow File option.

Just search Ubuntu's Software Center!

Installation through command line:

sudo apt-get install glogg

I chose this one over Multitail as the latter is actually an ncurses GUI running inside a terminal, while glogg is a true GUI (Qt). – Didier L Jan 22 '16 at 10:30
this one is very good: simple, fast and highlight supports. – Nadir Oct 24 '16 at 09:32
It's a great tool unless you need Unicode characters – Amir Uval Nov 03 '16 at 16:46
This tool works nicely for parsing/coloring different logs produced by software. I just wish that it would have support for plug-ins. – wojci Mar 03 '17 at 11:32
Having tried both, I find ksystemlog is highly superior to glogg. – Ayberk Özgür Aug 15 '18 at 13:20

Some options are: Swatch and KSystemLog

There's a log viewer built into Ubuntu, which can also open any log file, called System Log.

After desperately searching, then trying out lnav and many other log viewers for the macOS, I finally found the most powerful solution with least things to learn:

Microsoft Excel!

Create a blank sheet
Import your log file as text data and select delimiter accordingly

...Now you have all the super powers of tabular data manipulation!

Excel is quite useful and many of us using Windows at work already have it, so it is good for log file analysis, but does this also `tail` the log file, adding new data as it is logged? – RufusVS Sep 17 '20 at 13:47
@RufusVS I believe that will require some macro or scripting, if possible at all. – dz902 Sep 18 '20 at 06:58
That's what I thought. The original question was for a log "watcher" not log "analyzer", so Excel on its own is not sufficient. – RufusVS Sep 19 '20 at 21:04
Yeah I realize that. Landed on this question when searching for an easy-to-use log visualizer / analyzer and all of a sudden found Excel could do the job so might as well post it here just in case :) – dz902 Sep 20 '20 at 02:45
