OneAgent release notes version 1.225

Rollout starts 20 September 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 command-line interface to collect a subset of the full OneAgent diagnostics data right 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 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.

.NET

• Improved OneAgent .NET code module stability capturing unsupported headers for outgoing HTTP requests. (ONE-62154)

Go

• Resolved issue with CPU overhead introduced by OneAgent Go code module caused by signal masking on Linux to block Go asynchronous preemptions. (ONE-62300)

Watchdog

• Resolved an issue in which, on Windows, if a OneAgent process got a reused PID and subsequently became unresponsive, the watchdog, when terminating that process, could also terminate all children of the process. (APM-322928)
• Fixed issue in which watchdog could abort after log rotation. (APM-317898)

All modules

• Fixed code module injection that was skipped in certain cases on Solaris 10. (ONE-63640)

• Improved OneAgent shutdown speed in cases where ActiveGate isn't reachable/doesn't respond. (ONE-62069)
• Resolved OneAgent crash in `rpm` when a strict seccomp filter has been applied to the process by a security tool such as Falcon Sensor. (ONE-62034)

OneAgent Installer

• Resolved problem with insufficient privileges when setting custom SELinux file contexts during auto-update for OneAgent installed in non-privileged mode. (APM-313554)
