The first batching pass (bacac06) left critical-severity alerts on the
immediate-print path. That's still per-event spam for any persistent
critical (e.g. PrintPaperRollCritical fires every 30s Grafana evaluation
cycle when paper is <5%). Caught immediately after deploy: CUPS queue grew
0 → 8 jobs in 8 minutes from a single firing PrintPaperRollCritical.
This commit aligns with the operator's verbatim ask ("one alert an hour"):
- Critical-severity alerts now go into the digest buffer, NOT the
immediate-print path. The digest payload already shows severity tags
per alertname, so the operator still sees "[critical] X" in the printout.
- The explicit `alert_channel=thermal_print_immediate` label still bypasses
batching, but only on NEW fingerprint arrival — it triggers a flush of
the CURRENT digest (with the new alert included), then clears. Repeat
webhooks for the same fingerprint dedupe in the buffer until the next
hourly tick OR until the alert resolves. No fingerprint can spam.
- `add_to_digest` now returns bool (True = buffer grew, False = dedup /
resolution / disabled) so the immediate-label path can flush only on
state transitions.
Net effect: max 1 thermal print per BATCH_INTERVAL_MIN per alert fingerprint,
regardless of severity. Rules that genuinely need same-second paper opt in
via `alert_channel=thermal_print_immediate` (currently zero rules use this).

The thermal printer drained overnight (2026-05-18/19) because the old
notify.py POSTed one print job per Grafana webhook fire. With 9
concurrently-firing alerts (zabbix-postgres + fc-devicemgmt + brochure
+ PrintPaperRollLow), every evaluation cycle stamped fresh CUPS jobs
onto the queue until the operator physically powered the printer off.
This refactor:
- Adds env-var config: THERMAL_PRINT_ENABLED (master kill switch),
BATCH_INTERVAL_MIN (default 60), BATCH_MAX_PENDING (default 50).
- IRC delivery stays per-event (operator wants the live stream).
- Thermal routing now:
* critical/disaster/page severity OR alert_channel=thermal_print_immediate
-> print immediately
* alert_channel=thermal_print -> enqueue into hourly digest
* RESOLVED -> remove from digest buffer (no resolution-spam prints)
* else -> IRC only, no thermal
- Background digest_loop thread flushes the buffer hourly (or sooner
if buffer hits BATCH_MAX_PENDING). Digest payload is a single
Print.Web /api/print/alert POST listing distinct alertnames + per-rule
target counts.
- New POST /flush endpoint (manual operator force-flush; useful for
testing without waiting an hour).
- GET / returns config + buffer depth + per-stat counters for observability.
Net effect: max 1 thermal print per BATCH_INTERVAL_MIN for batched
warnings, plus immediate prints for criticals. Closes the 2026-05-18/19
alert-storm incident.

Mirrors the live `puppet` alert group from
FlowerCore.Notes/scripts/monitoring/alerts.yml into the K8s ConfigMap so a
future in-cluster Prometheus inherits the ruleset automatically.
Source of truth remains the Notes file (live Podman Prometheus on noc1).

Two new preventive alert rules added to the kubernetes-state group of the
K8s migration target ConfigMap. The live Podman Prometheus on noc1 has
already been updated via FlowerCore.Notes/scripts/monitoring/alerts.yml +
sudo cp + podman pod restart monitoring (this commit only locks it in
the bluejay-infra K8s mirror so a future migration carries it forward).
MultusMemoryPressure (critical, thermal_print): fires when kube-multus
working set exceeds 80% of its memory limit for 5m. Catches the next
multus OOM cascade BEFORE it kills the daemon cluster-wide. The 2026-05-10
21h outage hit because no alert fired on the rising multus working set;
only downstream blackbox / Traefik / service alerts triggered, after the
fact.
NamespacePendingPodBacklog (warning): fires when any single namespace has
>25 Pending pods sustained for 30m. Catches the operator-leak avalanche
pattern (orphan pods from a crashed reconciler emitting children without
ownerReferences) before it cascades into a CNI OOM.
See FlowerCore.Notes:

Mirror of FlowerCore.Notes/scripts/monitoring/alerts.yml fc-signage-marquee
group into the K8s migration target apps/monitoring/noc-monitoring.yaml so
that future migration of the noc1 Podman monitoring stack into RKE2
inherits the marquee alert ruleset automatically.
Three rules added:
- MarqueeDroppedFramesHigh (5% / 5min / warning)
- MarqueeRenderLatencyP99High (16ms / 10min / warning)
- MarqueeAnimationDurationDrift (10% / 15min / info)
All three gated with `unless on() absent_over_time(metric[7d])` so they
don't fire during the metric-not-yet-published window before Track 3
IR-21 source IMPL ships the MarqueeMeter into Common + Web + WPF.
Live source-of-truth (the noc1 Podman Prometheus reads from
/opt/monitoring/prometheus/alerts.yml) was updated and reloaded
in the same session — Notes commit 300daa0 carries the matching
alerts.yml + Grafana fc-signage-dashboard.json change.
Per feedback_monitoring_k8s_target_vs_live_podman: this file is the
forward-looking K8s migration target, NOT what the live Podman
Prometheus reads. ArgoCD-syncing this file does NOT push alerts to
the live monitoring stack.
Companion to:
- FlowerCore.Notes 300daa0 (live alerts.yml + Grafana panels deployed)
- docs/signage/marquee-performance-telemetry-design.md (Track 3 IR-21 spec)
- docs/signage/marquee-animation-phases.md (Track 6 13-phase coverage matrix)

Three new Prometheus alert rules for the print-services group, all routed
to thermal_print via alert_channel label (Grafana contact point ->
irc-notify -> Print.Web /api/print/alert):
- PrintPaperRollLow (warning, 5-10% remaining, 5m for)
- PrintPaperRollCritical (critical, <=5% remaining, 2m for)
- PrintJobDeadLetter (warning, any new dead-letter in 15m)
Source-of-truth gauge is print_paper_remaining_percent (Print.Web OTEL),
which is hydrated from the active PaperRoll row at process startup
(Print.Web@<TBD> HydrateMetricsAsync) so the gauge isn't blind for an
arbitrary window after every deploy.
Self-referential humor: low-roll alerts route to the printer that's
running out of paper, so it announces its own paper-out warning on its
remaining paper.

agent-zero ollama-proxy had 172 historic restarts (now stable).
Root cause: liveness/readiness probes hit /api/tags which proxies
through to BLUEJAY-WS Ollama (10.0.56.20:11434). When the workstation
Ollama is slow or offline, nginx fails over to the edge1 backup —
but the failover takes >1s and the kube-probe default timeoutSeconds=1
gives up first. Three failed probes → kubelet kills the container.
Fix:
- Add nginx local healthz endpoint (200, no upstream).
- Liveness probe → /healthz (proves nginx itself is alive).
- Readiness probe stays on /api/tags but with timeoutSeconds=5 so
failover to backup completes before the probe times out.
This decouples liveness from upstream availability — kubelet only
restarts the proxy when nginx is genuinely dead, not when Ollama is
slow.
Longhorn coverage gap: K8s emits "snapshot becomes not ready to use"
events constantly during the hourly snapshot lifecycle (1047
snapshots, all readyToUse=true on inspect). Those events were the
only signal we had — purely transient lifecycle noise, not actionable.
Add:
- longhorn scrape job (longhorn-backend.longhorn-system.svc:9500)
- NetworkPolicy egress rule for longhorn-system port 9500
- 4 new alerts in 'longhorn-storage' group:
- LonghornVolumeDegraded (>15m) — replica unhealthy, auto-rebuild
- LonghornVolumeFaulted (>5m, critical, thermal print) — data loss
- LonghornBackupStale (no completed backup in >36h) — recurring job
silently failing
- LonghornNodeUnhealthy (>5m) — node ready=false
zabbix-web 7 restarts and Print.Web 12:55 stop investigated — both
are stable now, no actionable cause found in journal/events. Adding
KubeContainerRestartingFrequently in the previous commit will catch
recurrence of either.

Followup to 05a273d. After deploy, six PoolDepleted/Deficit alerts
went pending again because the publisher emits per-status gauge
series (fc_desktop_pool_depleted{template,status,alert_level}) and
the historical Warming/BelowDesiredSize series stay at value=1 even
after the template transitions to status=Ready. Filtering by
alert_level=Critical/Warning was not enough — those labels are baked
into the stale series too.
Replace with a join-based query: alert only when the canonical
"Ready" status gauge does NOT report ready=1 for the enabled
template. fc_desktop_pool_ready{status="Ready"}==1 is the publisher's
own current-state canary and never goes stale.
Verified against the live cluster — query returns 0 results when all
pools report healthy in their reconcile logs (no stale-label false
positives).

Followup to ab6ade4. Three issues uncovered after the rollout:
1. NodePort hairpin breaks scrape from same-node pod. Prometheus on
rke2-agent1 could reach traefik-metrics on .11/.13 NodePort 30900
but timed out on its OWN node's NodePort. Same problem would hit
kube-state-metrics + cert-manager whenever prometheus reschedules.
Fix: scrape via ClusterIP svc DNS instead of NodePort. NodePorts
stay in place for external/Podman scrapers.
2. probe-traefik-services failed for grafana, prometheus, guac with
non-200/3xx codes. grafana + prometheus are behind Traefik basic-
auth (every endpoint returns 401), so drop from probe surface —
health is covered by the in-cluster monitoring-* scrape jobs.
guac.iamworkin.lan was deprecated when Guacamole moved under
desktop.iamworkin.lan/guacamole/ — drop it.
3. acme path was wrong (root 404). Use /health.
Coverage adds (probe-traefik-services):
chat, dist, dms, menuboard, messageboard, presentations, retail,
ttsreader. All of these have IngressRoutes serving root at 200/3xx.
NetworkPolicy egress rules added so the new ClusterIP svc scrapes work:
- traefik-system: port 9100 (metrics) — separate from data-path 8080/8443
- kube-system: port 8080 (kube-state-metrics)
- cert-manager: port 9402 (controller metrics)
Out-of-band fix during this audit:
- Print.Web on edge2 was inactive (clean exit at 12:55 CDT, root cause
unclear — systemd Stopping signal). Restarted. Service back on 5200.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Live audit on 2026-04-26 found 14 firing alerts caused by stale probe
targets, blackbox TLS verify failures, and stale state-as-label series.
Plus three K8s scrape sources (kube-state-metrics, cert-manager,
traefik) that exposed NodePorts but were not in any scrape config.
Fixes
- probe-remotedesktop: switch http_2xx -> https_internal. Blackbox does
not trust step-ca root, so /health was failing with x509 unknown
authority while the app served 200s.
- probe-agentzero-nuc: short svc form (agent-zero.agent-zero.svc:80)
instead of *.cluster.local. The FQDN form was being rewritten to the
Traefik VIP by the CoreDNS iamworkin.lan template + ndots:5 search
expansion, then 5s timeout.
- probe-agentzero-local + probe-ollama-local: removed. 10.0.58.100 is on
HOME VLAN and not reachable from cluster pods. Workstation/AI-laptop
Ollama monitoring belongs to host-side Puppet, not cluster blackbox.
- snmp-cloudkey: commented out. The Cloud Key Gen2+ runs unifi-core
(controller), not an SNMP agent. Was generating "connection refused"
every 30s.
- RemoteDesktopPoolDepleted / RemoteDesktopPoolDeficitSustained:
filter on alert_level=Critical / Warning|Critical + enabled=true.
The publisher emits one series per template per status without
resetting old series to 0, so the historical Warming/BelowDesiredSize
series stayed at 1 and the alert kept firing on stale labels.
- RemoteDesktopTlsExpiry: match by job, not hostname-only instance.
The probe sets instance=https://desktop.iamworkin.lan/health so a
hostname-only label match never fired.
- EpsonPrinterDown for: 5m -> 30m. EcoTank sleeps after ~5 min idle and
SNMP times out, so 5m guaranteed nightly noise.
Coverage adds
- kube-state-metrics scrape (NodePort 30901). Required for the new
pod-state alerts and a long list of standard K8s SLO queries.
- cert-manager scrape (NodePort 30902). Required for the
CertManagerCertificateNotReady / RenewalFailed alert pair documented
in project_cert_manager_prometheus_scrape.
- traefik scrape (NodePort 30900) on all three nodes.
- probe-traefik-services: HTTPS probe (https_internal) over the 17 main
iamworkin.lan hosts so any Traefik-fronted service returning non-200
shows up as a single named probe failure.
- blackbox-config: add the https_internal module that the new probes
reference (was only in the FlowerCore.Notes scripts/monitoring copy,
not in the live ConfigMap).
New alerts (kubernetes-state group)
- KubeContainerRestartingFrequently (>5 restarts/h)
- KubeContainerCrashLooping (>3 restarts/15m, thermal print)
- KubePodNotReady (Pending/Failed/Unknown >15m)
- KubePodImagePullBackOff (>10m)
- KubeDeploymentReplicasMismatch (>15m)
Without these, the agent-zero ollama-proxy 172x restart loop was
invisible for ~3 days. Same gap would have hidden the fc-php
php84-app-probe ImagePullBackOff orphan (cleaned up out of band).

Companion to the Prometheus alert rules landed in e44e9a0. The
Prometheus rules were loading but never delivered — the monitoring
stack has no Alertmanager configured; **Grafana** owns alert
routing via its built-in engine + webhook contact point to
irc-notify.monitoring.svc:9119. Without a matching Grafana alert,
the Prometheus rules just show up in the Prometheus UI and page
no one.
Adds 6 Grafana alert rules in a new `RemoteDesktop` group under
the AI Stack Alerts folder:
- remotedesktop-web-down (3m) — probe_success{job="probe-remotedesktop"} < 1
- remotedesktop-metrics-stale (10m) — fc_desktop_session_events_total series absent
- remotedesktop-pool-depleted (5m) — fc_desktop_pool_depleted > 0
- remotedesktop-pool-deficit-sustained (10m info) — fc_desktop_pool_deficit > 0
- remotedesktop-session-churn-spike (5m info) — launch rate > 20/min
- remotedesktop-tls-expiry (6h critical) — cert < 2 days to expiry
Each uses the standard Grafana 3-stage pipeline (query → reduce →
threshold) matching the existing AI Stack + Infrastructure alert
patterns. Labels: service=remotedesktop + severity (warning/info/critical).
Default route is `IRC #alerts` via the existing webhook contact point.
Parity with the Prometheus rules (which already fire internally
for the Prometheus UI + any future Alertmanager integration).
Grafana restart picks up the new provisioning on next reload.

Adds two egress allows to monitoring-netpol so Prometheus can scrape
FlowerCore.RemoteDesktop:
1. fc-desktop namespace on port 8080 — direct ClusterIP service
target (remotedesktop-web.fc-desktop:8080).
2. traefik-system namespace pods on ports 8080 + 8443 — covers the
Traefik VIP hairpin path for the `https://desktop.iamworkin.lan`
scrape target (CoreDNS wildcard resolves iamworkin.lan hostnames
to the LB VIP; after kube-proxy DNAT, egress needs the backend
pod port allowed per feedback_netpol_dnat_backend_port).
Without these, the fc-remotedesktop scrape times out with "context
deadline exceeded" even though the monitoring-netpol already allows
the 10.0.56.0/24 CIDR — post-DNAT the destination is a 10.42.x.x
pod IP, not the VIP.

Three additions to the monitoring ConfigMap, each targeting
FlowerCore.RemoteDesktop:
- **Scrape jobs** (2 new):
- probe-remotedesktop: blackbox http_2xx against
https://desktop.iamworkin.lan/health every 30s. Feeds the
RemoteDesktopWebDown alert.
- fc-remotedesktop: direct /metrics scrape against
desktop.iamworkin.lan for the fc_desktop_session_events_total
and fc_desktop_pool_* series.
- **Alert group `remote-desktop`** (7 rules in alerts.yml):
- RemoteDesktopWebDown (3m) — /health probe failing
- RemoteDesktopMetricsStale (10m) — absent metrics series
- RemoteDesktopPoolDepleted (5m) — pool deficit + depleted flag
- RemoteDesktopPoolDeficitSustained (10m, info) — persistent
below-desired pool size
- RemoteDesktopSessionChurnSpike (5m, info) — launch rate
>20/min
- RemoteDesktopRecordingEventsDropped (15m, info) — 30m without
recording events while launches active
- RemoteDesktopTlsExpiry (6h, critical) — <2d cert renewal
window; aligns with feedback_acme_expiry_alert_threshold
- **Grafana dashboard mount**: new volumeMounts + volumes entry for
`dashboards-remotedesktop` backed by the grafana-dashboard-remotedesktop
ConfigMap (previously added as a standalone file in d4210c8).
Folder path /var/lib/grafana/dashboards/remotedesktop — picked up
by the file-provider with foldersFromFilesStructure:true so the
dashboard shows up in a "Remotedesktop" folder in Grafana.
No CRLF churn; pure 100-line insertion into LF-normalized file.

Synology NAS is configured with community bluejay_monitor
(→ snmp.yml auth 'bluejay_v2'), not public. public_v2 was returning
HTTP 500 from snmp-exporter for this target. Verified bluejay_v2
returns metrics.
Keeps printer (10.0.58.107) on public_v2 — Epson ET-3750 uses
community "public" as documented in its SNMP settings.
CoreDNS iamworkin.lan template + ndots:5 was hijacking
unrealircd.irc.svc.cluster.local lookups → Traefik VIP → timeout.
Every alert since ~2026-04-09 silently failed with "IRC send failed: timed out",
which also killed the thermal-printer path (routed through irc-notify).
Same fix pattern as guacamole@28b7600.
