--- title: "1.39.10 — Complete infrastructure health evidence" description: "Complete infrastructure health evidence for existing AWS installations and independent job-runner and scheduler liveness." date: "2026-10-23" tags: ["release"] canonical: "https://django-mojo.sitesmojo.com/changelog/1-39-10/" --- Complete infrastructure health evidence for existing AWS installations and independent job-runner and scheduler liveness. ### Changed - Fresh host CPU, memory and disk measurements satisfy host health coverage; CloudWatch host metrics remain optional supporting evidence. ### Fixed - Bind managed database and cache metrics to the configured AWS region and exact runtime endpoints, including current Aurora writers and replica-only cache lag. - Let existing read-only platform monitoring accounts read infrastructure health evidence without granting general cloud inventory access. - Collect runner and scheduler liveness through existing OS cron, independent of the job queue, and include the original evidence in snapshots. - Preserve logical node aliases and checked process identity; missing, stale, ambiguous or unproved evidence remains Unknown. ### Upgrade notes - Restart job workers and schedulers after upgrading; retain existing OS cron and expected host/channel declarations. - Host resource measurements require psutil in normal application deployment dependencies. - Enrolled sources collect liveness quietly while legacy health notifications remain disabled.
