Dynatrace SaaS release notes version 1.258

Rollout start: Jan 17, 2023

Announcements

Davis Assistant end of life

Dynatrace Davis Assistant will reach end of life on January 31, 2023. After this date, the service will be shut down, and interactions with Davis Assistant will no longer be possible. Existing integrations, for example, with Slack or Microsoft Teams, will cease to work at that time.

For options and best practices on managing the push of problem notifications to your preferred third-party incident management or ChatOps service, see problem notifications documentation.

DQL use cases

Cross Solutions | DQL

You can now see the most common use cases of Dynatrace Query Language (DQL) in DQL Use cases.

New features and enhancements

Duplicate settings items

Cross Solutions | Settings

You can now duplicate items on most settings pages with the new Duplicate context action available for the individual rows.

Duplicate settings

Settings API now accepts host groups by name

Cross Solutions | Settings

You can now create settings objects for host groups using their names and not only the already available internal identifier. It opens up the possibility to provision settings before the first OneAgents of a host group has been deployed and connected.

Problem mode timeframe

Cross Solutions | Problems

The problem mode now expands to the analysis time of the problem instead of staying focused on the exact problem timeframe. It provides you with a wider range of values for analysis in the Dynatrace web UI.

Event timeout on configuration change

Cross Solutions | Problems

Events triggered by metric event configurations now time out after the configuration gets disabled or deleted. The default timeout is 15 minutes.

Management-zone rules based on dimensional log data

Cross Solutions | Settings

You can now add rules for including log-based dimensional data to management zones. As an alternative to filtering logs by entities, you can define rule conditions based on log file names and log attribute keys and values. For more information, see Management-zone rules.

Improved matching of language runtime versions based on the NVD feed

Application Security | Vulnerabilities

We improved the matching process for cases where NVD vulnerabilities contain an incorrect set of affected versions when using wildcards.

This will lead to a drop in open vulnerabilities for customers who see false matches.

Alert on monitoring issues

Infrastructure Monitoring | Kubernetes

A new Monitoring not available alert:

  • Is available in Kubernetes settings, under Anomaly detection > Cluster. To activate it, turn on Detect monitoring issues.
  • Detects when API monitoring is down, for example, when:
    • An endpoint is no longer reachable.
    • Your credentials have expired.

monitoring-down-alert

For details, see Alert on common Kubernetes/OpenShift issues: Cluster alerts.

Alert on cluster pod saturation

Infrastructure Monitoring | Kubernetes

A new Pods saturation on cluster alert:

  • Is available in Kubernetes settings, under Anomaly detection > Cluster. To activate it, turn on Detect cluster pods saturation.
  • Detects the overall cluster pod saturation.

For details, see Alert on common Kubernetes/OpenShift issues: Cluster alerts.

Alert on workloads with non-ready pods

Infrastructure Monitoring | Kubernetes

A new Not all pods ready alert:

  • Is available in Kubernetes settings, under Anomaly detection > Workload. To activate it, turn on Detect workloads with non-ready pods.
  • Detects if there are any non-ready pods in a workload for a specified amount of time.

For details, see Alert on common Kubernetes/OpenShift issues: Workload alerts.

Fine-grained settings for Cloud application and workload detection

Infrastructure Monitoring | Kubernetes

You can now configure Cloud application and workload detection independently for Kubernetes, Cloud Foundry, and plain Docker environments. The setting:

  • Requires OneAgent version 1.257.
  • Is enabled by default.

Logs on the Kubernetes namespace details page

Infrastructure Monitoring | Kubernetes

There's a new Logs section on the Kubernetes namespace details page.

New dimension value support for Opentelemetry metrics

Apps & Microservices | Opentelemetry

You can now pass dimension values also as boolean and integer; they will be converted to strings upon ingest.

Apps & Microservices | Distributed tracing

For GraphQL traces whose tracing system is Dynatrace, the Code level tab shows links to Span events and Span attributes.

Cross Solutions | Dashboards

You can now print a dashboard to a PDF file from Chromium-based browsers (Chrome, Edge, Opera) and Safari.

  1. Display the dashboard you want to print to a PDF file.
  2. Select More () > Print PDF in the upper-right corner of the dashboard.

Printing a dashboard to PDF from Firefox is not yet supported. For essential details, see Print a dashboard to a PDF file.

Screenshots for on-demand executions

Digital Experience | Synthetic Monitoring

You can now capture screenshots for successful on-demand browser monitor executions triggered via the UI. This functionality was previously available only via the API. Note that without this feature enabled, screenshot capture for on-demand executions is the same as for scheduled executions.

Screenshots for successful on-demand executions

Rerun on-demand executions

Digital Experience | Synthetic Monitoring

For on-demand executions of synthetic monitors, you can now rerun an execution with the exact configuration defined, for example, with metadata defined via the API. Select the Rerun icon next to an execution on the On-demand execution page.

Rerun on-demand execution

Updated preset dashboard for Synthetic Monitoring

Digital Experience | Synthetic Monitoring

The preset Synthetic Monitoring dashboard now includes several updates, including Data Explorer visualizations in place of custom charts, an example honeycomb visualization, and others.

Universally unique identifier matcher in DPL

Cross Solutions | DPL

You can now match Universally Unique Identifiers (UUIDs), such as social security numbers, using Dynatrace Pattern Language (DPL). See DPL Universally Unique Identifiers.

Dynatrace API

Component
Resolved issues

Cluster

  • Added configurable limit for the number of top dimensions in multidimensional analysis view. (TI-4678)
  • Fixed extracting generic entities from event metadata that was unintentionally disabled for Dynatrace Managed deployments. The feature is now available. (DAVIS-3137)
  • Fixed an issue that prevented a user with correct IAM permissions from creating a custom metric with regex condition. (TI-4287)
  • The tag placeholder for problem notifications now supports contextual tags. (DAVIS-3003)
  • Fixed an issue causing metric evidences to show an invalid start- and end-timestamp. (DAVIS-2965)
  • Fixed the changed aggregation of metric events using the metric `builtin:kubernetes.container.restarts`. (APM-391034)
  • Fixed numeric request attribute service filter in multidimensional analysis and distributed traces. (TI-4544)
