Five things deprecated, each verified against the DEPLOYED script before being
deleted rather than assumed superseded:
infra/410_disk_usage_alerts.yml -> disk-usage check (infra/400)
infra/420_system_healthcheck.yml -> liveness check (infra/400)
infra/430_cpu_temp_alerts.yml -> cpu-temp check (infra/400)
32_zfs play 2 (monitoring half) -> zfs-health check (infra/400)
34_nut play 2 (entirely) -> ups-status check (infra/400)
Nothing is lost by the swap. The old system_healthcheck.sh only computed uptime
and pushed, which is exactly a liveness heartbeat. The old disk monitor was
WEAKER than its replacement: it checked "/" alone at 80%, where the new one
walks every real filesystem at 85%.
Deleting the playbooks was not the hard part. The units they installed live on
the hosts, enabled, and keep firing regardless of what the repo says - two of
them were still pushing to uptime.contrapeso.xyz every 15 minutes across nine
machines. A playbook deleted without a cleanup leaves its output running
forever with nothing left to explain it. So infra/409_remove_legacy_monitoring
stops, disables and removes the units, deletes /opt/{disk-monitoring,
system-healthcheck,nodito-monitoring,zfs-monitoring}, and removes the orphaned
hand-written ups-heartbeat.sh. It ends by grepping for any surviving Kuma
reference and reporting it. Kept permanently and idempotent, so a rebuilt or
restored host cannot quietly bring them back.
A trap avoided: the monthly ZFS scrub lived INSIDE 32_zfs play 2. Deleting the
play wholesale would have silently stopped scrubbing the pool - and an
unscrubbed pool makes the health check meaningless, because it would have
nothing true to report. That play is now scrub-only and check-runs ok=5
changed=0.
ZFS pool capacity added as a sixth condition to the zfs-health check. `zpool
status` reports a 95% full pool as perfectly ONLINE, so capacity has to be read
separately with `zpool list` - and it is the failure you get warning of rather
than the one you discover. Threshold 80%, because ZFS allocation degrades badly
past roughly that and fragmentation is hard to undo. The pool is at 47%.
Verified both directions: passes on the real pool, and a simulated 91% exits 1.
Also fixed the waste recorded in c2de6db: the healthcheck role installed its
dependencies once per CHECK rather than per HOST - 29 apt transactions
estate-wide for a curl already present, and the slowest part of every deploy.
It now deduplicates within a play run, and the redundant standalone
daemon_reload is gone (the systemd task already does one).
site.yml updated, which exposed that services/gatus was never in it. It now runs
before the three registration playbooks, since registering endpoints against a
Gatus that is not yet serving would simply fail.
Verified: no legacy timer remains on any host; 83 endpoints, 83 UP, 0 DOWN.
