Who this is for

This article is intended for administrators and app users.

What you will learn

In this article, you'll learn how to set up Davis events pipelines to mask email addresses in the event.description field.

Before you begin

Prior knowledge

Prerequisites

  • Dynatrace SaaS environment powered by Grail and AppEngine.
  • You have both openpipeline:configurations:write and openpipeline:configurations:read permissions. To learn how to set up the permissions, see Permissions in Grail.

Steps

  1. Go to Settings > Process and contextualize > OpenPipeline.
  2. Select Davis events.
  3. On the Davis events page, select the Pipelines tab.
  4. Select Pipeline.
  5. Provide a name for your pipeline, for example, MaskEmailPipeline.

An example of a newly created a renamed Davis event pipeline

  1. On the Processing tab, select Processor and set the processor to DQL.

  2. Provide a Name for your processor, for example, Mask event.description.

  3. Set the DQL processor definition field to the following DQL query:

    parse event.description, "LD:content ([a-zA-Z0-9.!#$%&*+-/=?^_{|}~]+'@' LD '.' LD):email"
    | fieldsAdd event.description = replaceString(event.description, email,"xxx@xxx.xxx")
    | fieldsRemove email

    This DQL query extracts email addresses from event.description, replaces them with a placeholder, and removes the extracted email field.

An example configuratin of Davis event pipeline processor used for masking

  1. In the Sample Data field, provide a JSON example of event.description containing an email, for example: 
    {
    "event.description": "Test_email@dynatrace.com"
    }
  2. Select Run sample data.
  3. In Preview result, inspect the result to verify that email addresses are masked as expected.

An example of testing a Davis event pipeline processor with sample data

  1. Review your pipeline configuration.
  2. Select Save to apply the changes. Your new Davis event pipeline will be enabled by default.

Processing rules applied to the Davis event pipeline don't affect the Davis problem pipeline. To ensure masking is applied consistently, you need to configure the same masking rules for the Davis problems pipeline.

Conclusion

You have learned how to create Davis event pipelines, and can now mask emails from the event description.
