2022-05-27 - Giraffe is now maintained at https://github.com/library-data-platform/giraffe and has been updated to support the new Okapi log format.

Because Giraffe was created to use an outdated version of Okapi's log, and Giraffe hasn't been updated to consume the most recent version, the current Okapi log has to be formatted to match that of the old format. 

Old format:

New Format:

Steps to transform the new format into the old format simply by Find and Replace:

  1.  Change the timestamp with the following regular expression:
    1. Find "2022-02-16T19:30:[0-9][0-9].[0-9][0-9][0-9]-05:00" and replace with "2022-02-16"  (... content must be adapted to the actual log. Here the content is applicable to the log above).
  2. Remove all the contents inside the brackets. The following regular expression looks for everything that's between the first open bracket and last closing bracket, including the open and closing brackets in between.
    1. Find \[(.*?)\] and replace with "" (empty strings)
  3. Tabs must be replaced by spaces.  Between the date and the timestamp there is a tab
    1. Find "\t" and replace with " " (1 space)
