OneAgent release notes version 1.225

Rollout start: Sep 20, 2021

With this release, the oldest supported OneAgent versions are:

Standard Support

Enterprise Success and Support

OneAgent diagnostics on a host

If you don't have access to the Dynatrace web UI or you would like to script diagnostic data collection, you can use the oneagentctl command to collect a subset of the full OneAgent diagnostics data directly on the host where OneAgent is installed. For more information, see Create support archive.

SHA-2 signed installers on Windows 2008 R2

Starting with OneAgent version 1.225, the installer is signed using the SHA-2 algorithm. Consequently, Windows 2008 R2 hosts are required to have SHA-2 code signing support installed. If you use Windows Update, the updates were offered to you automatically (KB4474419 and KB4490628). If, however, your Windows 2008 R2 system doesn't support verifying SHA-2 signed installers, OneAgent auto-update and installation won't work if Applocker is configured to block unknown publishers and/or security warnings may be displayed. For more information, see the Microsoft 2019 SHA-2 Code Signing Support requirement for Windows and WSUS announcement.

Java

  • Added tracing support for Spring Kafka–based message producers and consumers. To enable this as a OneAgent feature
    1. Go to Settings and select Server-side service monitoring > Deep monitoring.
    2. Expand the New OneAgent features section, find Spring for Apache Kafka, and turn it on.

z/OS

  • The addition of OpenTelemetry interoperability for Java on z/OS makes it possible to enrich traces with project-specific additions and to extend end-to-end traces. For details and instrumentation samples, see OpenTelemetry interoperability for Java on z/OS.
  • oneagentzos-R12250.pax is now available
  • The second qualifier in the installation datasets has a single-digit sub-version (fix version). For example, the AUTHLIB dataset is named:
    DT.R12250.SZDTAUTH
    instead of:
    DT.R122500.SZDTAUTH
