Survlog is a convenient OS X application to store log file locations and essentially tail those files.
Some of the interesting features include grid view, for viewing all of your log files in one window (for those of us that need to watch 3-4 log files at once).
The ability to see local and remote log files(Using SSH and OS X Keychain).
Think of it like a bookmarking tool with quick instant access to your most needed logs. Survlog is currently in a public beta stage.
