The best Tail GUI

What is the one single best GUI program for tailing log files you've come across?

From stackoverflow

• Tail4Win is good enough for me.

• Emacs. I have a custom (simple) mode called `angry-fruit-salad-log-view-mode'. It is a minor mode that tails a file and enables highlight-changes-mode, so that new changes that come into the file while tailing are highlighted, but gradually fade to the normal text color over time. (Both tailing a file and highlight-changes-mode are built-in to Emacs.)

  (defvar angry-fruit-salad-log-view-mode-map
    (make-sparse-keymap))
  
  (define-minor-mode angry-fruit-salad-log-view-mode
    "View logs with colors.
  
  Angry colors."
    nil " AngryLog" nil
  
    (cond (angry-fruit-salad-log-view-mode
           (auto-revert-tail-mode 1)
           (highlight-changes-mode 1)
           (define-key angry-fruit-salad-log-view-mode-map
             (kbd "C-c C-r")
             'highlight-changes-rotate-faces)
           (if (current-local-map)
               (set-keymap-parent angry-fruit-salad-log-view-mode-map
                                  (current-local-map)))
           ;; set the keymap
           (use-local-map angry-fruit-salad-log-view-mode-map))
  
          (t
           (auto-revert-tail-mode -1)
           (highlight-changes-mode -1)
           (use-local-map (keymap-parent angry-fruit-salad-log-view-mode-map)))))
  

  Mark Pim : +1 for your naming :)

• Marc Lehmann's improved root-tail - http://www.goof.com/pcg/marc/root-tail.html

  It lets you tail multiple system log files, and other log files, on your root window, combine them, colour the text. It's simple, powerful and very useful. Runs on Linux, and probably runs on other Unix systems.

• On Windows I really like BareTailPro.

  Fredrik Mörk : +1; have used it for a good while now, and it has really made my day a couple of times.

  Nordin : I also use BareTail (the free edition), which is good enough for my need. (1 up vote for u, flowers ;-))

• The SMS Trace log viewer works as well.

• Kiwi Enterprises' Kiwi Log Viewer is awesome! (no affiliation with them, just a happy customer)

• What about free tail programs, which is the best?

  Roland Tepp : Not particularly useful as an answer. My question was designed to find out exactly that.

• On Windows, I like mTAIL

• A great windows tool with tailing, highlighting, filtering, columnizing and a rudimentary Eclipse integration is Log Expert. Also has a SDK and is free for both non-commercial and commercial use.

  Roland Tepp : Excellent... I'll be trying this out, but for now it seems to do mostly everything I need it to do :)

• TailMe is my favorite stand-alone Windows tail GUI.

  When using Eclipse, I really like nTail.

• $ less +F something.log
  

  I know you said GUI, but less is my favourite tail. Passing +F on the command line, or pressing F when viewing a file, puts it into "follow" mode just like tail -f, but with much more flexibility.

  Say you're watching the logs and you see an error scroll past and off the screen. Press Ctrl-C and you drop into normal less, where you can page up and down, regex search through the entire file (find that error you saw, and others like it), pipe bits of it through shell commands, etc. Once you're done inspecting the file just press F again and you're back in "follow" mode.

• On Mac os X, Survlog

  I should mention I work for grasscove and created this product :)
