Kubernetes Agent v1.9.16

Includes Java Agent v2.2.68

July 16, 2026

Feature Added a cgroup_version tag to kube_node_perf
- Distinguishes unified (v2) / hybrid / legacy (v1) / unknown values (provided as a tag only, with no new JSON field).
Fixed Fixed CPU throttle time being collected lower than the actual value in cgroup v2 environments
- Corrected an issue where throttled_usec (μs) from cpu.stat wasn't converted to ns, causing values to be collected about 1000x lower than on v1.
Caution
After this release, cpu_throttledtime values on cgroup v2 nodes may appear much higher (about 1000x) than before. This reflects a correction of a value that was previously undercounted by 1000x, not an actual increase in throttling.
Fixed Fixed memory Max Usage not being collected in cgroup v2 environments
- Changed to collect the Max Usage value from memory.peak.
Fixed Fixed blkio (disk I/O) metrics not being collected at all in cgroup v2 environments
- Replaced the io.stat parser.
Caution
Starting with this release, blkio metrics will begin being collected on cgroup v2 nodes. Please note that values that were previously not collected at all will now start flowing in normally.
