New features and enhancements

Product news

End-of-support news

The End-of-support news page now has a Dynatrace Managed section that clarifies our end-of-support policy. We use that page to communicate our de-support plans well in advance, so we recommend that you review it regularly to prepare for support changes from Dynatrace.

Internet proxy configuration for air-gapped deployments

You can now configure a proxy configuration in the Cluster Management Console for air-gapped (offline) deployments. The configured proxy is used by external problem notification services, such as ServiceNow, Jira, and webhooks.

Sign-in page mode configuration is now available for embedded admin user account

To change the sign-in page mode in previous versions, there had to be at least one cluster admin when sign via SSO. Now, when SSO is down, you can sign in to the cluster via the /admin page and adjust the sign-in page configuration.

Extended automation is enabled with "after installation" token Cluster Token Management scope

A cluster administrator that wants a fully-automated cluster setup was limited to using only REST API authorized by Service Provide API token scope. We've extended this token with Cluster Token Management scope. Now, a user can also automatically generate other tokens as needed, such as a token with read/write settings.

Available and reserved space values for cluster node storages have been adjusted

We've adjusted the values we show in Cluster Management Console - cluster nodes page and in cluster events so they match the behavior of truncating data. In practice, new values are more restrictive to ensure cluster deployment health robustness. You may observe less available space and more reserved space.

Improved navigation

We have added a new settings group breadcrumb item to Settings 2.0 pages linking to the first setting in a settings group.

Account permission label in Cluster Management Console renamed

Account permission View product usage & manage account info has been renamed Edit billing & account info to match the permission name in Dynatrace SaaS.

Operating systems support

Rocky Linux 9.0 added

We have added support for Rocky Linux 9.0.

Ubuntu 21.04 dropped

Ubuntu 21.04 is no longer supported for new installations. We still maintain existing deployments and allow upgrades. This note is to inform you that Dynatrace Managed version 1.258 will be the last one that you can upgrade to on an unsupported operating system.

    Application Security

    • Enabling OneAgent feature "Java code-level security evaluation" no longer leads to usage reporting for Application Protection even when Application Protection is not enabled on the cluster. (CASP-17791)

    Cluster

    • Resolved an issue in which, in a Dynatrace environment running in multiple data centers, if the problem environment was configured to not do conflict resolution on the database level, problems sometimes were automatically closed through an unrelated manual problem closure on a past problem. (DAVIS-2294)
    • Fixed an issue with some OneAgent-raised events, for example, high CPU, being auto-closed after 6 hours, even if the underlying issue still persists. This could also cause problems to be closed early when all of their events get auto-closed too early. (DAVIS-2324)

    Update 140 (Build 1.250.140)

    This is a cumulative update that contains all previously released updates for the 1.250 release.

    Update 145 (Build 1.250.145)
