OneAgent now correctly reads the cluster name for server instances that were configured for dynamic clusters (using the <server-template> option). The cluster name is added to PG/PGI calculations, meaning that previous, incorrect PG/PGIs will change. (HOST-3204)
Corrected computation of host CPU usage counters when CPU time counters wrap around, which can happen when the host has been running for a very long time. (HOST-3356)
Updated permissions for log files located in the os subdirectory of the OneAgent log directory to allow read/write only for the owner (600 for Linux). (HOST-3193)
The metric for low connectivity events raised by the OneAgent OS module now visualizes not timeouts but a summary of timeouts and resets. (HOST-3047)
Improved detection of volatile Podman containers in the OS module. (HOST-3335)
Corrected detection of Podman containers created by systemd services. (HOST-3283)
Disabled Windows network drive monitoring in response to API hanging in certain scenarios. (HOST-3206)
Java
Improved detection of third-party vulnerabilities in nested JAR files. (OA-18215)
Improved the attack protection feature for SQL to prevent false positives for some special characters. (OA-18511)
Resolved issue that prevented cookies from being considered for attack protection and vulnerability detection in Jakarta Servlets (servlet 5). (OA-17925)
Fixed an attack protection and vulnerability detection issue that, if ServletRequest or HttpServletRequest was implemented via proxy, could result in an UnsupportedOperationException. (OA-17476)
All modules
Support archive cleanup, which removes old support archive directories recursively, no longer follows symlinks (prevents unwanted removal of files outside the support archive directory). (OA-17713)
General
Resolved issue with HostID source on Azure/AWS (HostID is now recalculated on Azure/AWS when HostIdSource is manually changed). (HOST-2690)
Fixed an attack protection issue that could result in attacks not being reported in some cases. (OA-17642)
.NET
AspNet sensor: improved handling for retrieving context in ASP-hosted WCF apps. (OA-19004)
Improved stability of the .NET code-level vulnerability/attack evaluation OneAgent feature. (OA-18405)
Go
Resolved issue causing crash upon injection into a statically linked Go app built with the `-extldflags '-static-pie'` option. (OA-17365)
Node.js
Fixed a memory leak caused by the Node.js code module, which was introduced by a module-internal optimization (since reverted). (OA-19275)
Update 196 (Build 1.271.196)
This cumulative update contains 6 resolved issues and all previously released updates for the 1.271 release.
Fixed compatibility with musl-libc builds that don't contain LFS function exports with a "64" suffix. (OA-20428)
The OneAgent JavaScript module's signature check is temporarily disabled by default. This was done to mitigate high network traffic between the cluster and OneAgent caused by JavaScript agents older than 2 years having an out-of-date signature, which resulted in an invalid signature check. In a follow-up issue, we will update the signature checking mechanism and enable the signature check as the default again. (OA-19400)
OneAgent Installer
The plugin module binaries and process execution have been restored to the bootstrapped OneAgent container deployment. (DMX-4807)
.NET
Fixed a OneAgent .NET code module initialization issue for applications using app domains with a restrictive permission set for accessing environment variables. (OA-19564)
Improved memory management for Real User Monitoring (RUM) for ASP.NET Core. (OA-19469)
Mainframe
Request attributes for MQGET in CICS now enabled. (OA-19413)
We've added the fileDomainCookies parameter, which you can use to prevent Dynatrace from adding cookies to file scheme domains. For details, see Disable cookies for file domains.
Fixed an issue where the regex provided for setting the x-dtc header was ignored when matching against the host name for same-origin XHR/fetch requests. (RUM-11838)
Update 162 (Build 1.271.162)
This is a cumulative update that contains all previously released updates for the 1.271 release.
