For Windows, OneAgent installation fails when invalid installation parameters are passed. Note that deprecated parameters, such as --set-infra-only and INFRA_ONLY, are no longer accepted; use --set-monitoring-mode instead.

For details, see Customize OneAgent installation on Windows and OneAgent configuration via command-line interface.

Fixes and maintenance

General Availability (1.327.44.20251118-165931)

  • Fixed an issue where log reports from containerized applications, which were logged in the local time zone without a time zone indication in the timestamp format, were ingested with an incorrect timestamp value. (OA-58490)
  • Fixed an issue where the Host availability metric had gaps in some cases. (OA-58293)
  • Events can now be deactivated. (OA-57726)
  • Fixed an issue with the Threading Sensor instrumenting an endless loop in KafkaMessageListenerContainer$ListenerConsumer. (OA-54736)
  • Fixed a memory leak in OneAgent's OTEL span sensor caused by thread-local variable retention, which led to excessive memory usage. The issue was resolved by optimizing memory management to ensure stable performance. (OA-54725)
  • Fixed an issue that led to missing data in ADO tracing. (OA-54606)
  • On Windows, boost::icontains makes use of a lock that takes a consistent amount of time. The replacement function does not use any lock. (OA-54564)
  • Fixed log streaming issues after a CICS Agent would unINIT, and then reINIT. (OA-54319)
  • Removed deprecated handling on OneAgent where HTTP requests would be identified as JavaScript Agent Requests based on the jsAgentFilename or jsAgentFilenameDebug from the application UEM setting. (OA-54219)
  • Fixed an issue where CICS Services were missing due to mishandling of certain types of paths, in particular paths that reused MQ msg ID and correlation IDs. (OA-53529)
  • Fixed a possible crash caused by the OneAgent .NET Code Module in a corner case related to duplicate namespace and class names. (OA-53327)
  • Memory usage was reduced for instances when the agent installer is downloaded from a tenant. (OA-52651)
  • Fixed an issue with Apache/NGINX/IIS that sometimes led to response body sizes not matching the content-length header, when bizevents are enabled and some compression is used (gzip, deflate, br). (OA-52314)
