A real log source was added the day after this doc's last verify
(2026-09-07): auditd logs now ship to Loki too, on the 6 hosts
carrying the auditd_hardening role, after a real incident where one
host's /var/log/audit filled to 100% with zero external visibility.
Updated the diagram to add the 4th branch (rebuilt via Nextcloud
Diagramming, re-exported) and added prose describing it. Also
corrected the diagram's DNS branch label (job=dns -> job=technitium-dns,
matching the doc's own already-correct evidence-screenshot caption).
Journald sizing config (1G rocky-docker override, 500M fleet default)
confirmed byte-for-byte accurate live on both.
1. Live-verify: journald persistent-storage config confirmed on two
hosts (1G vs 500M cap, matches the doc's claim exactly), Alloy
active confirmed across all 11 fleet hosts.
2. Fix KB: Alloy Agent Model was stale - version had moved from
v1.18.0 to v1.18.1 on all 8 'newer' hosts since last checked,
role's own default still unreconciled at 1.17.1. Fixed and
confirmed via re-fetch.
3. Pulled the full Observability Pipeline tree: Alloy Agent Model,
Log Flow, Metrics Flow.
4. Replaced both mermaid diagrams (broke this repo's Nextcloud-SVG
convention) with real diagrams built through the proper round-trip.
5. Evidence: real journald config dumps, plus 3 real Grafana
screenshots (host metrics dashboard, detailed Loki log stream
showing job=technitium-dns/docker/system, and the fleet-wide log
volume dashboard) - one screenshot round caught and fixed an
unredacted internal IP before being used.
6/7. Compelling-proof test passes; sanitize-check clean.
Same treatment as the security batch - real tech names, 'why this vs
the alternative' reasoning, heavy cross-linking, ranked/specific
tradeoffs instead of generic hedges.
Names real technology throughout (Vault, Authentik, pfSense,
firewalld, Wazuh) instead of staying generic, adds a 'why this
approach vs the alternative' section to every doc, cross-links
heavily between docs instead of treating each system in isolation.
