Related to #547 and #622 ## Samsung SSD Fix (#547) Samsung 980 and 990 series SSDs have known firmware bugs that cause them to report incorrect health status (typically FAILED or critical warnings) even when the drives are actually healthy. This is commonly due to incorrect temperature threshold reporting in the firmware. This change adds special handling to detect these drives and skip health status alerts while still monitoring wearout metrics, which remain reliable. The fix also clears any existing false alerts for these drives. Users experiencing these false alerts should update their Samsung SSD firmware to the latest version from Samsung, which typically resolves the issue. ## Docker Agent CPU Fix (#622) Addresses issue where Docker container CPU usage shows 0%. The Docker agent uses ContainerStatsOneShot which typically doesn't populate PreCPUStats, requiring manual delta tracking between collection cycles. Changes: - Fix logic bug where prevContainerCPU was updated before checking if previous sample existed, causing incorrect delta calculations - Add comprehensive debug logging showing which calculation method succeeded (PreCPUStats, system delta, or time-based fallback) - Add warning after 10 PreCPUStats failures to inform about manual tracking mode (normal for one-shot stats) - Add detailed failure logging when CPU calculation cannot complete Expected behavior: First collection cycle returns 0% (no previous sample), subsequent cycles show accurate CPU metrics. |
