Bug Fixes
- Windows: Fix CD-ROM drives being monitored by the disk check since Agent 7.73.0. The diskv2 check now uses the Windows
GetDriveType()API to properly detect and exclude CD-ROM drives, matching the behavior of the previous Python disk check. This fixes false alerts onsystem.disk.in_usefor CD-ROM drives with inserted media. - Fix a bug in the workload autoscaling controller where annotation-only edits (e.g.
autoscaling.datadoghq.com/preview) on a locally-ownedDatadogPodAutoscalerwere not picked up until the next.specchange or cluster-agent restart, because the controller gated re-sync on.metadata.generation(which annotations do not bump). Toggling burstable mode via the preview annotation now takes effect on the next reconcile. - MacOS agent GUI app needs to ignore SIGPIPE to avoid process termination.
- On macOS, preserve user customizations to
system-probe.yamlacross Agent upgrades. - Fixed a bug on Windows where the NPM TCP failure rate could exceed 100% and climb indefinitely.
