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.
