Announcements

Dashboards app - variable values always returned as strings

Warning Breaking change

Dynatrace version 1.277+ Dashboards app version 1.10.0+

  • Up to and including the current release (Dynatrace version 1.276), in the Dashboards app, values from query, code, and CSV variables have been automatically converted to numbers where possible.

  • Starting with the next release (Dynatrace version 1.277+, Dashboards app version 1.10.0+), however, all such variable values are returned as strings.

Problem: Starting with Dynatrace version 1.277, errors might occur in some existing Dashboards app dashboards that depended on the previous conversion (for example, your query expects a number, but it now receives a string).

Solution: Use DQL conversion functions in your queries to convert values as needed.

This change applies only to the Dashboards app in the latest Dynatrace, not to Dashboards Classic, and it does not take effect until Dynatrace version 1.277+.
