mrcharles 24b08aa592 docs(audit): document observability stack + Saturday OAM day plan
Operator-defined monitoring architecture (no tool duplication):
- Beszel (Cloudron VPS): CPU/RAM/disk metrics on all Proxmox hosts via Tailscale
- Uptime Kuma (Cloudron VPS): up/down alerting via Pushover
- LibreNMS (VMID 104, on-prem): SNMP polling for switches (non-Tailsale gear)
- Home Assistant (VMID 100, on-prem): power/temp instrumentation + alerting

Saturday 2026-08-01 is designated OAM Day: goal is 100% instrumentation
coverage across all four tools + centralized syslog.

## Current State: STABLE
The merged PFVCluster repo is fully operational across provisioning, DNS
infrastructure, Proxmox cluster ops, and k8s control plane.
## Completed Work
### Server Provisioning (validated on sectestbed-sandbox)
- [x] SetupNewSystem.sh deploys end-to-end to rc=0 (Debian 13 trixie)
- [x] Security hardening: SSH, SCAP-STIG, Wazuh, 2FA (SSH+Cockpit+Webmin)
- [x] NTP: redundant pfv-netinfra-01/02 (192.168.3.252/253), synced stratum 3
- [x] DNS resolv.conf: managed static file pointing at netinfra pair
- [x] Test suite: 5 tests (framework, safe-download, 2fa, https, system-req)
- [x] VM validation harness: git-based deploy + auto-rollback + guest-agent access
### DNS Cluster (pfv-netinfra-01/02)
- [x] Production Technitium config replicated from tailscale-router (read-only)
- [x] 124 zones on both nodes (knel.net + reverse DNS)
- [x] pfv-netinfra-01 = PRIMARY, pfv-netinfra-02 = SECONDARY
- [x] Zone replication via rsync systemd timer (every 60s)
- [x] Credentials + 2FA replicated identically to production
- [x] Both LAN IPs resolve knel.net device names + recurse externally
- [x] **DHCP migrated from pfv-netboot → netinfra-01/02** (ISC failover-peer, primary/secondary). Both `normal`, 333 active leases load-balanced. DNS+NTP now handed out as 252/253. Netboot DHCP stopped + disabled. Webmin DHCP module on both nodes.
### Proxmox Cluster Ops
- [x] 5 of 7 hosts fully performance-tuned (tsys1/3/6/7/9)
- [x] **Full ground-truth audit 2026-07-30** (network + storage + compute + switches)
- [x] **Cross-rack NFS root cause identified:** core-sw01 LAG hash=layer-2-3 (no L4),
g16/g17 cable mismatch (3 of 4 links active), static mode (no LACP)
- [x] **tsys4/tsys5 storage changes documented:** new NVMe (CT500P1 500GB), relocated
SK hynix SSD, D3 changed to USB HDD, /mnt/albert + /mnt/backup added
- [x] **Console symlink bug fixed:** udev rule singular→plural mismatch broke all 7
console ports after reboot
- [x] **Portable audit tooling built:** probe-storage.sh, probe-network.sh,
conman-console.py, snmp-switch-audit.py (AGPLv3-friendly, config-driven)
- [ ] **Memory goal (≤80% actual): PASS fleet-wide** — highest is tsys9 at 69%
- [ ] CPU ~50%-idle goal: fleet idles 0-5% (under-utilized; chase via workloads, not hardware)
- [ ] tsys4: PVE 9.1.5 (behind fleet 9.2.5), needs upgrade
- [ ] tsys5: NVMe + SK hynix SSD installed but NOT configured
- [ ] tsys2: pending rebuild from Win10 to Proxmox
### Kubernetes Control Plane (k3s HA — LIVE)
- [x] 3-node k3s HA control plane deployed: cnode1/2/3 (v1.36.2+k3s1, embedded etcd)
- [x] **All traffic over Tailscale IPs** — no LAN IPs in node status or certs
- [x] All 3 cnodes tainted `control-plane:NoSchedule` (zero user workloads)
- [x] 13/13 health checks pass (verify.sh): nodes Ready, etcd quorum,
Tailscale IPs, CoreDNS, API server, workload isolation
- [x] Scripts in `k8s/`: wipe, install-cp, join-servers, post-setup, verify
- [x] Kubeconfig saved to `~/.kube/config.pfv-k8s` (gitignored, embedded certs)
- [ ] Workers (wnodes) not yet joined to this cluster
- [ ] Distro decision: **k3s chosen for regular R&D cluster**. Talos docs
preserved in `k8s/docs/` for future ITAR/classified cluster.
### PDU Management (powerman on pfv-tsys1 — LIVE)
- [x] Cyclades AlterPath PM10i (10 outlets) managed via powerman over serial
- [x] USB-DB9 adapter (Prolific pl2303) with stable udev symlink
`/dev/cyclades-pm10`
- [x] powermand listening on `127.0.0.1:10101` + Tailscale `100.121.189.98:10101`
- [x] All 10 outlets defined as `outlet-1` through `outlet-10`
- [x] Validated: outlet 10 cycled off → on (8/8 test checks passed)
- [ ] Rename outlets to match physical devices (Friday onsite)
### UPS Management (NUT on pfv-tsys1 — LIVE)
- [x] **APC Smart-UPS C 1500** fully reporting via NUT usbhid-ups + APC HID 0.100
- [x] upsd listening on Tailscale `100.121.189.98:3493` (port 3493)
- [x] Local upsmon (master) configured for graceful hypervisor shutdown
- [x] Home Assistant credentials generated (`homeassistant` user in upsd.users)
- [x] Scripts in `ups/`: discover, setup (idempotent), status
- [x] Home Assistant NUT integration **configured via REST API** (`ups/setup-ha-nut.sh`)
- [x] **Key fix:** upsd now listens on LAN IP (192.168.3.11) in addition to
Tailscale — HAOS runs Tailscale as an isolated add-on, so the HA container
cannot route to Tailscale IPs. Shared vmbr0 bridge provides instant LAN path.
- [x] **Key fix:** udev rule covers BOTH `usb` and `hidraw` subsystems (driver
opens raw `/dev/bus/usb` after setuid drop, not `/dev/hidraw`)
- [ ] **Tripp Lite UPS blocked:** driver matches TrippLite HID 0.85 subdriver
but fails reading 878-byte HID Report Descriptor (EAGAIN via USB hub).
Needs physical reseat to direct motherboard USB port or cable replacement.
Driver masked to prevent restart-loop spam.
- [ ] **Home Assistant NUT integration:** configured and live (3 sensors:
battery charge, status, status data). This APC (FW 02.2, mfg 2012) does not
report `ups.load` over USB HID — confirmed via both NUT and apcupsd tests.
No wattage for Energy Dashboard; smart plug on UPS output is the practical
path. apcupsd package conflicts with nut-server (mutually exclusive).
### Console Management (ser2net telnet(rfc2217) + conman on pfv-tsys4 — LIVE)
- [x] 7 network switch/router consoles managed via ser2net + conman
- [x] **USB enumeration problem SOLVED:** udev rules pin each adapter by
ID_PATH (physical USB port topology) to stable `/dev/consoles/<name>`
symlinks that survive reboot regardless of enumeration order
- [x] ser2net exposes all 7 consoles on telnet(rfc2217) TCP ports (2001-2007)
bound to **Tailscale IP only** (`100.70.77.93`)
- [x] conman connects to TCP ports for logging + multiplexing (7 log
files active in `/var/log/conman/`)
- [x] Both ser2net + conmand enabled via systemd (survive reboot)
- [x] conmand systemd unit created (Debian package doesn't ship one)
- [x] conmand remote access enabled (loopback=off, port 7890)
- [x] Old `/root/conmap` + manual `screen` workflow replaced
- [x] **Stair-stepping fix:** ser2net accepter changed from raw `tcp` to
`telnet(rfc2217)` so conman's telnet NVT negotiates binary mode properly
- [x] **Validated 6/7 consoles working** via conman from workstation
(core-sw01, tor3-mgmt, tor3-stor, rrinfra-rtr, r2-tor-top, subodev-torsw)
- [ ] **pfv-r2-sw (port 2007): DEAD** — zero bytes at all baud rates
(1200-115200), adapter present and mapped correctly (/dev/ttyUSB3).
Physical issue: device powered off, console cable disconnected, or
console port disabled in device config. Requires onsite investigation.
### Ansible AWX (tsys-awx — LIVE)
- [x] AWX 24.6.1 deployed via AWX Operator 2.19.1 on k3s single-node
- [x] Accessible at `http://tsys-awx.knel.net` (port 80, LoadBalancer via k3s ServiceLB)
- [x] Admin login: `admin` / `REDACTED_PASSWORD`
- [x] PostgreSQL 15 (bundled, 8 GiB PVC on local-path)
- [x] VM resized: 32→60 GB disk, swap converted to swapfile
- [x] Scripts in `awx/`: install-k3s, deploy-awx, verify-awx
- [ ] HTTPS/TLS not yet configured (currently HTTP on port 80)
- [ ] Execution environments not yet customized
### Repo Merge
- [x] KNELServerBuild merged into PFVCluster (history preserved)
- [x] Directory structure reorganized (provisioning/, tests/, perf/, docs/)
- [x] All docs gardened: links fixed, stale refs removed, tailscale.md updated
