Dynatrace SaaS release notes version 1.245

Announcements

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. To stay tuned, keep an eye on our release notes.

New features and enhancements

Product news

  • Understand and replay Android app crashes with Session Replay

    The latest enhancement to mobile app monitoring with Dynatrace® Session Replay provides you with a movie-like replay experience of the final user actions of all user sessions that terminate in a crash. With this update, frontend developers can identify the root causes of app crashes not only on iOS but also on Android.

  • Unlock the observability value of log data with processing at scale

    Dynatrace Log Monitoring is now enhanced with advanced processing, making the data locked in logs actionable and completing the observability picture on the Dynatrace platform. Easy-to-use pattern matching lets you extract any data from logs, transform and manipulate attributes, and filter or drop insignificant logs.

Log processing

Starting with Dynatrace version 1.245, Log Processing is no longer in Preview. Its capabilities are now expanded very widely to execute all kinds of log transformations on ingest with new commands and functions.

Also, we added information on data types that you can use in creating log processing rules.

Disable Service insights at a host level

Cross solution - Settings

Now you can disable Service insights monitoring at an individual host level, either using a host settings page or OneAgent on a host API - Technology monitoring configuration when Service insights monitoring is enabled at the environment level.

Log ingest

Starting with Dynatrace 1.245, we extended the maximum payload size for log ingest API to 5 MB.

Problems

Problems now indicate and cross-link impacted SLOs based on the SLO entity selectors and the identified impacted.

Metrics

Prometheus Summary metric type support has been added. For existing annotated exporters, the Summary metrics are ingested by default.

Service insights

You can now disable service insights for a specific technology on selected hosts via the Dynatrace web UI and Dynatrace API when global monitoring is enabled in the Monitored technologies setting for that technology.

  1. Go to Hosts or Hosts Classic (latest Dynatrace) and open the host details page for the host you want to configure.
  2. On the host details page, select More () > Settings.
  3. In the Monitored technologies table for that host, find the technology, expand that row, and turn off monitoring of that service on the selected host.

Memory profiling

Applications & Microservices

The memory profiling page now opens with the flame graph as the default visualization. However, if you access memory profiling from the problem page, the hotspot table remains the default visualization. It enables you to immediately understand the highest contributor. When sharing the link to a specific page, the selected view mode is persisted in the URL.

Credential vault

Synthetic Monitoring and Extensions 2.0

To access the credential vault, go to Credential Vault. It is no longer accessible via Settings.

Dynatrace API

To learn about changes to the Dynatrace API in this release, see Dynatrace API changelog version 1.245.

Component
Resolved issues

Cluster

  • Failure detection - request attribute conditions "equals" and "not-equals" on floating point numbers now work correctly. (APM-379472)
  • Resolved issue with reporting Cloud Application Security Units consumption not being correctly reported in application-only mode under certain conditions. Resolved issue with reporting Cloud Application Security Units consumption not being correctly reported in application-only mode under certain conditions. (CASP-16582)
  • The Infrastructure Monitoring mode `--set-infra-only` OneAgent install parameter is now correctly recognized by the server. (APM-379864)
  • Fixed a problem that caused the "copyFromHostName" flag in rule-based service detection to be lost, causing service merging/splitting to not work as configured. Before this fix, for an "Opaque and external web request" rule that has a {{publicDomainName}} section with {{copyFromHostName}} enabled but no {{transformations}} specified, that {{copyFromHostName}} flag would not be applied correctly (but still be shown as enabled). In 1.244 and 1.245, if you observe the problem happening even after this fix is applied, you can mitigate it by reading and storing the rule again via the REST API. In any case this will happen automatically after upgrading to 1.246. (APM-379679)

Application Security

  • Resolved issue in which the "Host coverage" percentage on the "Application Security overview" page was calculated using an excessive total number of hosts, which rendered a coverage percentage that was lower than in reality. (CASP-16608)
