New Dependency Discovery now uses open connections in combination with DNS records to discover only hostnames for which the Gremlin Agent has seen an active connection. Users should no longer see dependencies discovered for services that only make DNS queries to a particular hostname, but never actually connect to them.
New When running either the docker-linux, containerd-linux, or crio-linux container driver, Disk experiments against containers now correctly impact the target's volume resources. Both ephemeral storage and external volumes are supported. See the Disk experiment for more details.
New During impact, the Disk experiment no longer keeps the files it produces hidden. This allows external monitoring systems like the kubelet to correctly measure changes in disk usage. See Ephemeral storage consumption management
Fix Fixed a bug where the Gremlin Agent would not find a target container's cgroup when running on cgroup1 with subsystems defined at different paths.
Fix Fixed a bug where the Gremlin Agent could not parse cgroup data about a target container when both a cgroup2 hierarchy and a cgroup1 named hierarchy were present. This is common on systems like BottleRocket when the Admin Container is enabled.
