Live Tail

Papertrail's event viewer is realtime. When using Papertrail for Papertail, we appreciate that it:

  • feels communicative. Imagine "tail -f" on dozens of systems, but with pause, search, infinite scroll, and alerts.
  • stays out of the way, so it's there when we need it and not asking for my attention when we don't.
  • plays well with my browser. We expect new tabs, scroll indicators, and copy-and-pasted URLs to work the way they do in other Web sites.

These might sound simple, but they aren't, and nuance matters. The fact that we "sweat the details" as Papertrail's creators makes a huge different for us as users.
