OneAgent release notes version 1.225
Rollout start: Sep 20, 2021
With this release, the oldest supported OneAgent versions are:
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.
