New features and enhancements

Improved Unified analysis pages

Automations | Ownership

Team name is now displayed in the Ownership Add Ownership tag list.

Metric key event throttling threshold change

Alerting

Metric key events are now throttled at 200 (instead of 100) simultaneous alerts.

Delete expired maintenance windows easily

Settings | Maintenance windows

The Maintenance windows page now makes it easy to delete expired maintenance windows. Just select Delete expired maintenance windows, set the number of days, and select Search to list maintenance windows that have been expired at least that many days. Select Delete to delete them.

Improved root cause analysis for services with Kubernetes workload events

Infrastructure Observability | Kubernetes

We have improved some root cause analysis scenarios regarding services with Kubernetes workload events.

Improved handling of long-running fetches of requests and traces

Application Observability | Services

To make better use of system resources, we adjusted the handling of a long-running analysis:

• Long-running fetches are visualized better.
• Analysis runs that take too long are stopped.
• Partial results are returned for fetches that have been automatically canceled.

This can reduce the overall load on the Dynatrace system and thus improve performance and system stability.

Application Security | Vulnerabilities

From now on, you can see remediation advice/description for SNYK vulnerabilities in our v2 API, third-party vulnerabilities page, the new vulnerabilities app and security events in Grail.

Apache Commons Compress version updated

ActiveGate | Security

The Apache Commons Compress version has been updated from version 1.21 to version 1.26.2 to address CVE-2024-26308 and CVE-2024-25710.

Resolved issues

General Availability (Build 1.294.42)

The 1.294 GA release contains 15 resolved issues.

Application Security

• Fixed the generation of the next page key when filtering security problems using management zones and sorting the results in descending order. (RSA-15138)

Cluster

• To resolve an issue in which ActiveGate token generation failed when given a long lifetime, the `expirationDate` now has the following constraints: it must not be set in the past and it must not exceed two years from the moment of creation. (PS-22548)
• For 0-duration point-in-time problems, the email notification doesn't stop with 'was open for', but now also reports the duration (0 ms) properly. (DI-14635)
• Fixed a bug that resulted in the creation of Kubernetes service entities without a namespace. (K8S-10030)
• Extension configuration statuses are no longer stuck in the loading state. (EXT-9986)
• Improved handling of a wildcard in queries for terms with `.` dots inside (like IP addresses). (LOG-7000)
• Fixed an issue that could temporarily prevent certain settings pages from working correctly on newly created environments. (PS-22946)
• Resolved a problem in which technology tiles on the "Technology overview" page sometimes displayed different instance and process group counts before and after selecting a tile. (HOST-5731)
• Multiple source entities are no longer being incorrectly extracted from logs. (PPX-2160)
• Replaced the `rx_pid` dimension with the `process.pid` dimension in the `dt.process.handles.file_descriptors_percent_used` metric. (HOST-5689)
• Enrichment logic that could cause Kubernetes service entity duplication was fixed. (K8S-9927)
• Resolved an issue causing cross-environment dashboards to not work after updating to Dynatrace Managed 1.288. (PAPA-17822)

Documentation

• Corrected the description of Java metric `builtin:tech.jvm.memory.runtime.total`. (OA-30456)

Elasticsearch

• Fixed an issue with user session queries containing the DATETIME function combined with MEDIAN, PERCENTILES, or COUNT(DISTINCT) functions. (GRAIL-28503)

Logs

• In Logs, on the "Log Viewer" page, when there are more than 100 columns to display in "Advanced mode", table formatting is switched to simple mode for better readability. This applies only to `logs` and not, for example, to `bizevents`. (LOG-7365)
