Context

Papertrail’s viewer shows links to see any message in context. Click the sender (orange) or program (blue) to jump to that message within the related stream.

If you haven’t tried context links yet, here’s 3 situations where they've helped us:

  • Infrastructure-wide history. While viewing a HTTP request log for a user-facing error, clicking access_log shows all Web requests. Because other Web servers in the group are also searched and the query (like an IP address or user ID) is preserved, Papertrail returns the end-to-end history.
  • Single-system impact. After spotting a kernel problem in a Unix syslog message, clicking the sender will show events from only that system.
  • Long events, like when a search matches one line in a multi-line exception. Click the log sender to see it all.

If you're used to grep, we've tried to adopt the best parts of its context and jettison those that we didn't like.
