OneAgent & ActiveGate release notes, version 1.153





  • Support for gRPC end-to-end tracing (beta)
  • Support for Couchbase (beta)


  • Monitoring of Windows Server Containers (Docker for Windows) has been improved with better detection of executable paths.
  • Docker topology on Linux is now also reported in cases when OneAgents are deployed in cloud infrastructure monitoring mode.

General improvements

  • OneAgent is now officially validated for proper installation on Fedora 28.
  • OneAgent uninstallation on Linux now properly restores runc configuration.
  • With OneAgent for AIX, it’s now possible to use openssl enc instead of uudecode during install and update procedures. The absence of uudecode and the presence of openssl enc is automatically detected.
  • OneAgent now properly detects Google Cloud Platform host IP addresses as well as projects from Google metadata.
  • OneAgent now properly parses run options for HAProxy monitoring.
  • OneAgent version 1.153 now provides new measurements for AIX LPAR hosts. With the introduction of kernel threads, it’s now easier to identify a logical partitions’ oversubscription to computation power, specifically in the area of logical CPUs. The additional counters for blocked threads suggest areas for potential reconfiguration.

OneAgent support changes

Dynatrace OneAgent will discontinue support for the following platforms and components within the next 6 months:

  • Java Virtual Machine 5 (all vendors, EOL by Oracle on May 31, 2015)
    OneAgent version 1.157 will be the last version to support this (planned for the end of 2018).
  • Node.js 4 (EOL by Node.js 31 in April 2018)
    OneAgent version 1.157 will be the last version to support this (planned for the end of 2018).
  • PCF versions 1.10.x, 1.11.x, and 1.12.x. Pivotal has already discontinued support for these versions. Please consult Pivotal’s support matrix for further details.
    OneAgent version 1.157 will be the last version to support this (planned for the end of 2018).
  • Kubernetes versions <= 1.6 are no longer actively maintained by the Kubernetes community.
    OneAgent version 1.153 will be the last version to support this.
  • OneAgent deployment on the following operating system versions for which the respective providers have discontinued support. OneAgent version 1.157 will be the last version to support these.
    • Ubuntu 12.04, 12.10, 13.04, 13.10, 14.10, 15.04, 15.10, 16.10, 17.04 (14.04 LTS, 16.04 LTS, as well as 17.10 and above will continue to be supported)

    • openSUSE 12.1, 12.2, 12.3, 13.1, 13.2, 42.1, 42.2
    • Windows 8

Cloud platform support

  • Dynatrace OneAgent now automatically detects Cloud Foundry hosts of technology type Diego cell. You’ll find this information as part of the Technologies host level property
  • The new technology type Diego cell is also available for auto-tagging, host and process group naming rules, and management zones.
  • Dynatrace OneAgent automatically derives tags and metadata from Cloud Foundry and Kubernetes environments and attaches it on respective processes. These tags and metadata (i.e., Kubernetes annotations) are now also automatically propagated to related services.
  • Dynatrace OneAgent can now also automatically monitor Golang applications without code changes in locked-down app-only scenarios. For details, consult Dynatrace documentation for app-only monitoring in Kubernetes, OpenShift, Google App Engine, and Heroku environments.
  • Dynatrace OneAgent Operator version 0.2.0 has been released. The release includes support for OneAgent resource settings and is also available as a RedHat certified operator image in the RedHat Container Catalog.


  • Application (ALB) and Network (NLB) load balancer types are now fully supported out-of-the-box together with the pre-existing (i.e., “Classic”) load balancer.

Important bug fixes

With this release of OneAgent and ActiveGate, we’ve resolved the following issues:

  • APM-136303 – non-root (non-privileged) mode of OneAgent was not correctly enabled after Linux kernel update
  • APM-138047 – LZMA decompression fails because of insufficient disk space on C:, broken required free space detection
