OneAgent Version 1.173 for Linux comes with support for RHEL distributions on the IBM Z platform. Read more about OneAgent for RHEL Z-Linux.
- Added support for Play Framework 2.7
- Added support for Azul Zulu 11 LTS for Linux, Alpine Linux 64-bit (x86), Windows (x86)
- Added support for Tengine 1.4.2 - 2.2.3 for Linux, Alpine Linux 64-bit (x86)
- Added support for Amazon Linux 2 (x86)
- Added support for Red Hat Enterprise Linux 6.9+, 7+ (s390x)
- Added support for Ubuntu 18.04 LTS, 18.10, 19.04 (s390x)
- We've completely re-designed the internals of the OneAgent installer for Windows. For details, see enhancements for OneAgent installer for Windows.
- As we announced two months ago, the
*.msiartifact of the OneAgent installer for Windows is no longer being built. The existing
*.msifiles, as well as the REST API endpoints, will remain in place for the time being, but they won't support the new versions of the endpoints. For details, see OneAgent for Windows enhancements for MSI-based deployments.
- Improved Oracle process recognition. Previously, all Oracle processes were represented by one Oracle process group and one Oracle process group instance on each host. Starting with OneAgent version 1.173, each Oracle process group will represent a single Oracle SID (unique identifier for every Oracle DB instance). The SID is part of the process group name, and is extracted from process names (Unix) or service description (Windows). Oracle processes not associated with any SID will now form an
Oracle other processesgroup. This includes the communication process, TNS Listener, so all incoming and outgoing traffic will be associated with the group. The
Oracle other processesgroup will keep the pre-rework identifier of the Oracle group, so all historic data will be available under the entry.
- Technology-specific stack traces for processes running inside containers will be analyzed by Dynatrace. See more information about crash analysis.
- Our support for Docker and containerD-CRI was adjusted to better handle changes introduced in Docker. Here's a quote from the Docker release notes: “In Docker versions prior to 18.09, containerd was managed by the Docker engine daemon. In Docker Engine 18.09, containerd is managed by systemd."
- Improved reporting of connections between processes running in Docker containers. Thanks to this improvement, Smartscape topology view of Docker processes is now even more accurate.
OneAgent support changes
Dynatrace OneAgent support of the following platforms and components will be discontinued within the next 6 months
- Announcing upcoming de-support for .NET Core 1.0 and 1.1 in November 2019 as it reached end-of-life on June, 27th 2019 - see .NET Core official support policy.
- PHP 5.6 support has been extended and will reach end-of-life in November 2019
- Pivotal Platform PAS version 2.3.x (Pivotal support for this version ends in June 2019. Consult Pivotal's support matrix for further details). OneAgent version 1.175 is the last version that supports Pivotal Platform version 2.3.x.
- WebSphere Application Server version 8.0 (EOS by IBM in April 2018) OneAgent 1.183 will be the last version that supports WebSphere version 8.0
- Java 6 WebSphere Application Server version 8.5 (EOS by IBM in April 2018) OneAgent 1.183 will be the last version that supports WebSphere version 8.5 with Java 6. Going forward, only the combination with Java 7 or higher will be supported
Cloud Platform support
- Dynatrace now also supports the Cloud Foundry Go buildpack on Linux for monitoring your Golang applications with the application-only monitoring approach for Cloud Foundry. Support starts with buildpack v1.8.41. Please note, full-stack monitoring was already supported and doesn't depend on the buildpack extension.
- Monitoring Windows Diego cells (or any other Windows BOSH VMs) requires version 1.2.1 or higher of the bootsprapping BOSH release due to the removal of the MSI artifact of the OneAgent installer (see the General improvements section above).
- We streamlined the API endpoint for configuring Cloud Foundry integrations and moved the endpoint to
/cloudFoundry/credentials. The previous endpoint
/virtualization/cloudFoundryCredentialshas been deprecated and requests are now redirected to
/cloudFoundry/credentials. Make sure to adapt your integrations with this API and double-check if your clients follow the redirect response from the API.
- Dynatrace fully supports vanilla Kubernetes 1.15 clusters with underlying Docker, containerd, and CRI-O container runtimes on Linux.
- The settings page for the Kubernetes API integration provides improved feedback about communication issues, such as issues with the certificate.
- We streamlined the API endpoint for configuring Kubernetes integrations and moved the endpoint to
/kubernetes/credentials. The earlier endpoint
/virtualization/kubernetesConfigurationshas been deprecated and requests are now redirected to
/kubernetes/credentials. Make sure to adapt your integrations with this API and double-check if your clients follow the redirect response from the API.
- We've added an availability chart for VMware ESXi devices similar to how we present host availability.
- Events are no longer generated for low ESXi host disk space for datastores that have zero-bytes capacity.
ActiveGate support changes
Here are the de-support plans for ActiveGate
- OneAgent version 1.177 will be the last version to support only 32-bit host IDs. By that time, all ActiveGates older than version 1.144 will need to be upgraded to the newer releases in order to properly support OneAgent 64 bit IDs. Failure to do this will result in OneAgent being unable to communicate with the Dynatrace Cluster via these older versions of ActiveGate. Other than that, this change will be completely transparent.
- Synthetic-enabled ActiveGate support for Windows Server 2016 is available with ActiveGate version 1.173.
For important bug fixes and other changes, as well as previous release notes, see the release changelog.
