Gremlin now supports Control Group v2 (cgroupv2) with Linux Agent 2.26.0.
What are cgroups?
Cgroups are part of the Linux process model, allowing you to allocate resources — such as CPU time, system memory, network bandwidth, or combinations of these resources — among user-defined groups of tasks running on a system.
Until recently, Kubernetes did not support cgroupv2, so there was no impact on Gremlin. With Kubernetes 1.25, cgroupv2 has been adopted, and cgroupv1 deprecated. Ubuntu, Amazon Linux, and other Linux distributions are migrating to cgroupv2 as well.
What do I need to do?
If you're using the latest versions of the Linux operating systems mentioned above, Gremlin recommends updating to the latest Gremlin Linux agent to avoid compatibility issues.
