PaaS token during OneAgent installation

Dynatrace tokens are displayed only once upon creation. Dynatrace stores them encrypted and you can't reveal them after creation.

To enhance token security, we modified the OneAgent download dialog. You now have to provide the PaaS token in the dedicated field or create a new token on spot. The token is automatically appended to the provided download and installation commands. For more information, see the OneAgent installation documentation for AIX, Linux, Solaris, or Windows.

Declarative process grouping

Starting with Dynatrace version 1.218, your custom process group definitions are migrated to Declarative process grouping available at Settings > Processes and containers. Starting with OneAgent version 1.217, only changes made to declarative process grouping settings will have an effect from now on. For more information, see Declarative process grouping.

OneAgent for Android: Bintray sunset

Starting with this release, public artifacts for OneAgent for Android instrumentation will be distributed only via the Maven Central repository due to the sunsetting of Bintray.

OneAgent for Android: closing unused connections

On Android, HTTP connections by system default have the keep-alive header set. The connection stays open for additional requests that may occur. Because of an Android bug, however, they also stay open after the server closes the connection.

Starting with this release, OneAgent keeps the connection open only if another request is expected; otherwise, the connection is closed. Removing unused connections in this way frees resources on your ActiveGate firewall.

Java
