Published date: 2023-09-11

Announcements

Thresholds API sunset

With the release of Dynatrace version 1.276, we will turn off the Thresholds API. Any requests to these endpoints will stop working. Migrate your automations to the Settings API instead. For more information, see the migration guide.

Azure API Management request metrics retired

Breaking change

As described in Microsoft documentation, Microsoft has retired the following Azure API Management requests metrics as of August 31, 2023.

Total Gateway Requests
Successful Gateway Requests
Unauthorized Gateway Requests
Failed Gateway Requests
Other Gateway Requests

Dashboards and alerts based on these metrics will no longer work.

New metrics are available in Azure API Management Service monitoring.

New features and enhancements

New matcher attribute in log storage configuration

Infrastructure Observability | Logs

You can now use the Log record level attribute in log storage configuration:

Log Monitoring Classic

View the origin of vulnerable libraries

Application Security | Vulnerabilities

You can now view the origin of a vulnerable Java software component in the remediation tracking for process groups and processes affected by a vulnerability.

For example:

For navigation details, see Remediation tracking.

Unified services for trace ingest

Application Observability | Services

We have enhanced support for OpenTelemetry and cloud-native monitoring with a new service type, Unified service. Unified services are based on OpenTelemetry spans ingested via the ingestion APIs and provide

Automatic baselining and Davis® AI integration
Automatic endpoint detection
New service metrics, such as response time, throughput, and failure rate
Advanced horizontal topology detection
Support for custom application metrics and application logs
Agentless support for Istio service meshes
Opt-in endpoint monitoring with new metrics

To get started, see Unified service.

Detection attributes highlights

Application Observability | Services Application Observability | Databases

Attributes used for detection are marked with an asterisk ✱ on the service and database, under Properties and tags.

Unified analysis screens for Kubernetes nodes

Infrastructure Observability | Kubernetes

You can now access new unified analysis list and detail page for Kubernetes nodes.

Advanced Kubernetes label filtering

Infrastructure Observability | Kubernetes

You can now apply multiple values simultaneously in the Kubernetes label filter.

Detailed OneAgent status in unified analysis host page

Infrastructure Observability | Hosts

The Properties and tags section of the unified analysis host page now displays the OneAgent status.

The status can be either active or inactive, along with a reason for the status.
Detailed status information is available for up to 24 hours. Beyond that, the status defaults to inactive.
An unknown status is displayed if data is unavailable.
The status may be delayed by up to 5 minutes.

RKE2 technology grouping

Infrastructure Observability | Hosts

We've added RKE2 technology per process group instance. RKE2 agents and RKE2 servers are now grouped into separate process groups.

High System Load events trigger process instance snapshots

Infrastructure Observability | Hosts

High System Load events will now automatically trigger process instance snapshots.

Timeout for "Detect pod backoff events" alert reduced

Platform | Davis AI

The timeout for Davis problem Detect pod backoff events (after which it is closed automatically) has been changed from 1 hour to 15 minutes.

Resolved issues

General Availability (Build 1.274.157)

The 1.274 GA release contains 21 resolved issues.

Component	Resolved issues
Application Security	1
Autonomous Cloud	1
Cluster	17
Synthetic monitoring	1
metric query	1

Application Security

On the vulnerability details page, the number of resolved process groups is shown independent of timeframe. (RSA-10953)

Autonomous Cloud

Corrected a Deployment page reference to point to the newly released Dynatrace Operator v0.13.0. (K8S-6907)

Cluster

The action validation in extension is now stricter to avoid incorrect error messages. (TI-7825)
Resolved an issue where very large problems could halt problem processing. (DAVIS-5701)
We now display errors from thrown by the execute endpoint. (EXA-7365)
Improved robustness to prevent very rare cases where root cause analysis was not performed when more than 1,000 baselining events were raised on the same entity within a few seconds. (DAVIS-5360)
Corrected the problems count in the weekly report. (DAVIS-5334)
We disabled obsolete custom process monitoring rules, fixing the issue in which it was impossible to delete them. (HOST-3507)
The status of problems that receive updates after resolving is now UPDATED instead of RESOLVED. The RESOLVED status is now unique between the previous and succeeding records for the same event ID. (DAVIS-5443)
Unicode whitespace characters at the end of an LQL query no longer cause an error. (LOG-4066)
Added extensibility to the new service UI. (TI-7916)
URL filters without a value are now ignored and no longer cause an error. (RUM-12092)
Resolved issue that prevented problem comments from being read shortly after a problem was raised if the problem was raised slightly into the future. (DAVIS-5356)
Fixed a race condition in the calculated service metric updating logic that could occur when two or more configuration updates were done within a short timeframe, which resulted in the metric not showing the correct data values until the next update refreshed the configuration. (TI-7634)
Removed unavailable dimensions in unified services' metrics. In the Data explorer, unified metrics (for example, `Response time`) are separated by the type of aggregation and represented as separate metrics. Previously, all metrics in the "Split by" allowed the same dimensions to be selected, and if an unavailable dimension was selected, "No data" was displayed. Now, the "Split by" field shows only those dimensions for which the metric contains data and a chart can be displayed. (TI-7960)
Corrected the new database overview page to show the correct throughput metric. (TI-7724)
Fixed issue during the process of restoring visit backups causing dropped visits. (RUM-12405)
Fixed a bug where live user sessions without visitor ID were dropped during rolling updates. (RUM-12292)
Cluster now waiting for connection responses from all ActiveGates after ActiveGate update. (Cluster wasn't waiting for all ActiveGates to respond if an attempt to connect to VMware was successful.). (HOST-3654)

Synthetic monitoring

Fixed an issue with validation of credentials in a customized script of a browser monitor on-demand execution. (SYNTH-6024)

metric query

Fixed an issue that caused HTTP 500 to be returned by the metric query/definition endpoints of the Timeseries API v1 if the User-Agent header was not set in the request. (CLUSTER-8252)

Update 173 (Build 1.274.173)

This cumulative update contains 1 resolved issue and all previously released updates for the 1.274 release.

Managed

Fixed the "Include backup of Log Monitoring v2 events" option in the backup configuration that didn't work correctly. (CLD-8000)
