I'd like to regex out the json

Hannes Benson

before parsing the json

Hannes Benson

I have the following processor set up

Hannes Benson

Copy code

operators:
      - type: regex_parser
        regex: '{(?P<body>.*)}'
        parse_from: body
        if: "body matches '^{.*}$'"
      - type: json_parser
        parse_to: attributes
        if: "body matches '^{.*}$'"
      - type: severity_parser
        if: "'severity_text' in attributes"
        parse_from: attributes.severity_text
        output: remove_severity_text
      - type: remove
        id: remove_severity_text
        if: "'severity_text' in attributes"
        field: attributes.severity_text

has resolved the issues, but now I'm not getting

trace_id

span_id

😕

Great, let me know if you need more help . If this is a generic heroku parser that you have created would love to have a blog from you. @Ashu do reach out if Hannes is interested.
