Announcements

Npcap installed by default starting OneAgent version 1.255

Starting with OneAgent version 1.255, the OneAgent installer on Windows installs the Npcap driver by default and the previously default option auto becomes deprecated.

This may cause potential network disruption during OneAgent installation on Windows Server 2016, or Windows Server 2019 build 1809 and Windows 10 build 1809 without the KB4571748 hotfix or any of its superseding hotfixes.

If your hosts don't have the KB4571748 hotfix, upgrade them now or use other documented options to prevent potential disruptions.

New features and enhancements

Added LPAR and region metrics for z/OS

  • LPAR metrics: GCPU time, zIIP usage, and zIIP time
  • Region metric: Consumed Service Units

To learn more, see Monitor LPARs and regions.

Improved injection driver blocklist handling in Windows containers

The injection driver now reads the blocklist from the host's registry instead of trying to read it from the container's registry.

OneAgent for Android

  • Updated Javadoc for class WebRequestTiming

OneAgent for iOS

  • Breaking change 8.257 drops support for Xcode 13, bitcode, iOS 9, and iOS 10. For Xcode 14 users, no change is required. If you need support for one of the desupported technologies, use OneAgent for iOS version 8.255.
  • Removed dependency on third-party library ssziparchive.

    JavaScript

    • Fixed an issue in which "dtrum.leaveAction" called with the action ID of an action that is not created with "dtrum" would cause the action to be closed earlier, and, if it was an XHR action, it incorrectly would be closed before XHR finished. Now "dtrum.leaveAction" will only close actions that were previously created by dtrum; otherwise, it does nothing and information is logged to the console about the incorrect usage. (RUM-8038)
