5. Validate Observability Data

In Dynatrace, press ctrl + k and search for Services. Dynatrace creates service entities based on the incoming span data. The logs are also available for some services

In this demo, you will be focussing on the Cart which does have logs and is written in .NET.

You can also query data via notebooks and dashboards (ctrl + k and search for notebooks or dashboards).

For example, to validate logs are available for cartservice, use one of the following methods:

Use the logs app#

  • Open the logs app.
  • Click the + icon and add a filter for service.name with a value cartservice
  • Run the query to see the latest cartservice logs
