Action "log.csv"

Write logs to the host filesystem in the CSV format.

Schema definitions

The log.csv action leverages the log.fs action and honors all its configuration properties.

definitions =
  config:
    type: 'object'
    allOf: [
      properties:
        serializer:
          type: 'object'
          default: {}
          description: '''
          Internal property, expose access to the serializer object passed
          to the `log.fs` action.
          '''
    ,
