Rollout start: Sep 11, 2023

Announcements

Red Hat Enterprise Linux support

Upgrade to this release of Dynatrace Managed is now enabled with cluster nodes running on Red Hat Enterprise Linux 8.x or 9.x.

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

Warning 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:

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:

load-origins-pg

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.

Share your feedback in the Feedback channel for the enhancements to OpenTelemetry trace-ingest (Unified Services) released w/ v1.274 (SaaS & Managed) in the Dynatrace Community.

Unified services for trace ingest

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.

Multi Label filtering

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.

OneAgent status

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.

    Application Security

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

    Cluster

    • Resolved an issue where very large problems could halt problem processing. (DAVIS-5701)
    • The action validation in extension is now stricter to avoid incorrect error messages. (TI-7825)
    • We now display errors from thrown by the execute endpoint. (EXA-7365)
    • 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)
    • 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)
    • Unicode whitespace characters at the end of an LQL query no longer cause an error. (LOG-4066)
    • 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)
    • Added extensibility to the new service UI. (TI-7916)
    • We disabled obsolete custom process monitoring rules, fixing the issue in which it was impossible to delete them. (HOST-3507)
    • Corrected a Deployment page reference to point to the newly released Dynatrace Operator v0.13.0. (K8S-6907)
    • 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)
    • URL filters without a value are now ignored and no longer cause an error. (RUM-12092)
    • 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)
    • 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)
    • 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)
