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.
