Dynatrace SaaS release notes version 1.237

Announcements

TLS 1.0 and 1.1 end-of-support for RUM data

Starting with April 2022, Dynatrace is retiring TLS 1.0 and TLS 1.1 for Dynatrace SaaS RUM data.

Session Replay masking v1 end-of-life

Starting with Dynatrace version 1.240, Session Replay masking v1 will no longer be supported. If your application uses the RUM JavaScript version 1.192 or earlier, you must update the RUM JavaScript to at least version 1.193 to enable masking v2. Otherwise, Session Replay will stop working once Dynatrace version 1.240 is live.

Classic user sessions page end-of-life

We are deprecating the classic User sessions page soon and replacing it with a more powerful page for session segmentation. This will happen with Dynatrace version 1.239 or later. To stay tuned, keep an eye on our release notes.

New features and enhancements

Log Monitoring

Starting with OneAgent 1.237, log file rotation patterns support a rotation identifier that doesn't have to be surrounded by any of the following characters: . _ - ( ) [ ]

Detected log files

Recognized rotation pattern

/var/log/access20220322.log
/var/log/access20220315.log
/var/log/access20220308.log

/var/log/access.20220322.120000Z.log
/var/log/access.20220322.090000Z.log
/var/log/access.20220322.060000Z.log

/var/log/access.#.#Z.log

Because of this change, some of the log files that were autodicovered by previous versions of OneAgent (OneAgent version 1.236 and earlier) may change their name. This may require adjustments in Log Monitoring settings such as:

  • Log events
  • Log metrics
  • Log custom attributes
  • Storage upload configuration

Metrics

  • Metric dimensions set by the Prometheus Metrics Ingest ActiveGate module are now harmonized with the dimensions set on builtin Kubernetes metrics as well as other ingest channels.
    The dt.kubernetes.workload.kind, dt.kubernetes.workload.name, and dt.kubernetes.cluster.name dimensions have been added, while k8s.<controllertype>.uid and k8s.<controllertype>.name have been removed.
  • The Kubernetes metrics builtin:cloud.kubernetes.pod.containers and builtin:cloud.kubernetes.pod.desiredContainers are updated for scalability reasons. The pod (and also the node) dimension are removed from these metrics. In return, three container metrics were added to the charts on the workload details page. The impact of this change to existing dashboards and custom alerts is described in the Q&A post.

Metric events

Deprecated fraction-based aggregations (OF_INTEREST, OTHER, OF_INTEREST_RATIO, OTHER_RATIO) reach end of support. Metric event configurations using one of those aggregations will be disabled.

Maintenance windows

Maintenance windows now support filtering based on generic entity types.

New DDU consumption overview page

We improved the existing DDU consumption overview page formerly available at Settings > Accounting > Davis data units overview and moved it to Account Management > License / Subscription > Overview > Davis data units. The new page offers a clearer overview with the additional functionality to group metrics consumption into a tree structure for easier drill-down analysis.

Settings security policies

These previously existing settings are now available to be used in security policies:

Settings > Monitoring > OS services monitoring Settings > Preferences > Network zones settings Settings > Preferences > Data privacy > Session Replay Settings > Web and mobile monitoring > Capturing > Resource capture for Session Replay Settings > Web and mobile monitoring > Web applications > Enablement and cost control Settings > Web and mobile monitoring > Mobile apps > Enablement and cost control Settings > Web and mobile monitoring > Custom applications > Enablement and cost control

Cluster

  • Added validation to problem notification custom integration URLs which checks that it is not site-local. (APM-353080)
