pipe as delimiter in regular expression

Above is my sample logging format which will be sent to fluentd, and I did regular expression as follow:

<parse>
  time_format %Y-%m-%d %H:%M:%S
  expression /^(?<timestamp>(.*?\|))(?<level>(.*?\|))(?<language>(.*?\|))(?<service>(.*?\|))(?<uuid>(.*?\|))(?<message>.*)/
  @type regexp
</parse>

Problem is when I render that one, pipe | is included in string. Please let me know how to ignore or skip | there? Thanks.

Solution

  • Just move the | outside of your group: ^(?<timestamp>(.*?))\|(?<level>(.*?))\|(?<language>(.*?))\|(?<service>(.*?))\|(?<uuid>(.*?))\|(?<message>.*)
