INJECT_FACTS_AS_VARS auto-injection of top-level facts is deprecated and removed in ansible-core 2.24. Use ansible_facts['architecture'] and ansible_facts['date_time']['epoch'] instead.
Disks
Partitions disks, enables periodic SSD TRIM, and optionally exposes S.M.A.R.T. disk health to Prometheus.
Configuration
See defaults/main.yml.
S.M.A.R.T. exporter
Gated by smartctl_exporter_enabled. When true, downloads and runs the
smartctl_exporter static binary as a root systemd service, polling smartctl
at smartctl_exporter_interval (default 30m).
smartctl_exporter_enabled: true
Pair with Prometheus:
prometheus_scrape_configs:
- job_name: "smartctl"

Temperature alerts
The grafana role provisions cumulative temperature thresholds: a rise fires
each newly crossed threshold (lower tiers keep firing), a fall resolves each
crossed-down threshold (ack), and the final ack fires when leaving the lowest
tier.
| Threshold | severity |
for |
|---|---|---|
| ≥48°C | warning | 10m |
| ≥50°C | warning | 10m |
| ≥52°C | warning | 10m |
| ≥54°C | high | 10m |
| ≥56°C | high | 10m |
| ≥58°C | critical | 10m |
| ≥60°C | critical | 5m |
| <20°C | warning | 10m |
Responsiveness is bounded by smartctl_exporter_interval (default 30m).
