General

  • Fixed possible duplicate reporting of IP addresses for database services (resulting in service detection on the cluster side creating a duplicate database service) when OneAgent's hostname resolver periodically updates DNS records. (OA-25100)
  • Fixed an incompatibility with the musl-libc `gcompat` library that could lead to a crash of any applications (no matter if linked against musl or glibc) that were executed on musl-libc with its `gcompat` wrapper library when OneAgent was loaded. (OA-26645)
  • The Kubernetes pod name can be determined from the hostname. On Windows, the fully qualified domain name was used instead of the host name, which could lead to incorrect pod name recognition. With this fix, the physical machine name is now used, which is the expected behavior. (OA-24453)
  • When resolving the DNS name fails on first try to connect to an SNMP device, datasource will retry the connection in the next interval. (EXT-8614)
  • Fixed OneAgent deployment on RKE2 instances (installation failed due to oneagenthelper process termination caused by insufficient permissions to access the containerd meta.db file). (OA-25919)

Java

  • The HTTP response body of business events is now properly captured even if GZIP compression happens outside the Servlet filter chain. (OA-24574)
  • Fixed a memory leak that occurred when Grail metrics were disabled. (OA-26888)

.NET

  • The request body is no longer stripped away when a Business Event rule to capture the request body is set. (OA-25428)

IIB

  • Dynatrace OneAgent code module for IBM ESB: Resolved issue that possibly altered customer message headers used for Dynatrace tagging. (OA-25465)

Mainframe

  • Distributed traces from CICS and IMS are now correctly marked as flawed if the node limit was exceeded. (OA-24964)

OS module

  • Fixed an issue in which a Spring Boot process was occasionally assigned to an invalid process entity. (HOST-4726)
  • Containers running in a private user namespace are now detected. (HOST-4485)
  • Fixed grouping and detecting Spring Boot version 3.2. (HOST-4912)
  • Java processes are now properly reported in cases when JRE is inaccessible from the OS module. (HOST-5252)

OneAgent Installer

  • Modified SELinux policies to allow `ioctl` syscall to access Dynatrace enrichment metadata files. (DMX-6756)

OpenTracing module

  • Starting with OneAgent 281, the OneAgent Envoy code module is no longer injected into (and there is no deep monitoring of) Envoy version 1.29+. Previously, Envoy could abort startup with an error in Envoy versions that no longer support certain features required by OneAgent. (OA-24962)
