New features and enhancements

OS services - Alert if service is not installed

Infrastructure Monitoring | Hosts

On the OS services monitoring page, you can now turn on Alert if service is not installed to alert you when an OS service isn't installed on a host.

Reporting cloud type for non-x86 platforms

Infrastructure Monitoring | Hosts

Due to a previous internal restriction, OneAgent on non-x86 platforms did not report a cloud type. This restriction has been lifted, and other platforms, such as ARM, now show the cloud type.

Events from OS services reported on separate OS service entity

Infrastructure Monitoring | Hosts

Previously, events from OS services were reported on the host entity. They are now reported on a separate OS service entity, which means you can use, for example, tagging, management zones, and profile alerting related to events and problem generation, and those events, problems, and OS service entities are visible only to specific users. If you have scripts or rules to filter OS service events from host events, you should update them.

Problem generated by OS service links to OS service entity page

Infrastructure Monitoring | Hosts

A problem generated by an OS service now links to the OS service entity page instead of to the host page with the OS service.

OS services - Alerting delay

Infrastructure Monitoring | Hosts

On the OS services monitoring page, you can now set an Alerting delay that defines how long an OS service must be in particular state before an event will be generated.

Tracing SNS-triggered AWS Lambda for Python & Node.js (manual)

Apps & Microservices | Distributed Traces

The Dynatrace AWS Lambda extension for Python and Node.js now supports tracing for AWS SNS. For details, see OpenTelemetry interoperability.

Expanded support for Google Cloud Run (Managed)

Apps & Microservices | Distributed Traces

Enhanced support to cover Generation1 (GVisor) and Generation2 (KVM) execution environments. For details, see Monitor Google Cloud Run managed.

Go

  • Fixed ptrace error handling for Go static monitoring. (OA-10248)
  • Fixed Go gRPC sensor, which was not able to patch existing W3C trace context headers provided by OpenTelemetry (double instrumentation). (OA-10582)

NGINX

  • The OneAgent NGINX module no longer incorrectly reports upstream requests when a client timeout cancels NGINX request processing before such upstream calls were actually made. (OA-10193)
  • Fixed a problem where OneAgent on NGINX could report traffic to the wrong service after changes in NGINX configuration and a subsequent NGINX reload. (OA-11345)

General

  • Vulnerability: The Python runtime used in Extensions 2.0 has been upgraded to Python 3.10.9. (OA-10610)
  • Vulnerability: Python runtime for Extensions 1.0 has been upgraded to 3.8.15. (EXT-2908)

OS module

  • The metric selector for the host cpu saturation event/problem is now "Host cpu usage %" instead of "Host cpu load". (APM-393334)
  • When an OS service alert is active and the service status changes (but still matches the alert criteria), OneAgent now stops the current alert and raises a new one with the title updated to match the new status. (HOST-1779)
  • The value passed with the Python -m parameter is now correctly used as a PG/PGI name. (HOST-1813)
  • Fixed Apache port detection from configuration files when the "-f" command line parameter is provided. (HOST-1923)
  • Improved the performance of the OneAgent OS module when a high number of Java code modules are running on the host. (HOST-1867)
  • AIX system: Process memory usage calculation has been adjusted. The previous formula was based on virtual memory usage. The updated formula is based on data and text resident set size. In general, this means a decrease in values of the `builtin:tech.generic.mem.workingSetSize` metric on AIX hosts. (HOST-1823)

Java

  • Fixed capture of HTTP method in Spring WebFlux HTTPClient 5.3+. (OA-10881)
  • Resolved an issue that could result in software components not being reported for fat JARs on Java versions earlier than 11. (OA-10749)
  • Fixed missing paths for outgoing HTTP requests in Reactor Netty 1.x when using `headersWhen()` in API call. (OA-10121)

.NET

  • Resolved a .NET HttpTagging v2 issue in which an already canceled HTTP request was accessed, resulting in a logged exception. (OA-11099)

  • Added a check to make sure, when calling `dtrum.addActionProperties`, that the action for the provided actionId exists. (RUM-8103)
  • Fixed an issue in synthetic, where actions would show slightly higher action durations and visually complete times. (RUM-8042)
  • Fixed an issue that could cause an action to be dropped, because it exceeded the maximum duration. (RUM-8195)
