Instead of creating a long-lived Vault token in Terraform (which gets
invalidated when Terraform recreates it), monitoring01 now uses its
existing AppRole credentials to fetch a fresh token for Prometheus.
Changes:
- Add prometheus-metrics policy to monitoring01's AppRole
- Remove vault_token.prometheus_metrics resource from Terraform
- Remove openbao-token KV secret from Terraform
- Add systemd service to fetch AppRole token on boot
- Add systemd timer to refresh token every 30 minutes
This ensures Prometheus always has a valid token without depending on
Terraform state or manual intervention.

Document TrueNAS CORE LDAP integration approach (NFS-only) and
future NixOS NAS migration path with native Kanidm PAM/NSS.

Evaluate options for replacing LLDAP+Authelia with a unified auth solution.
Recommends Kanidm for its native NixOS PAM/NSS integration and built-in OIDC.

WSDCGQ12LM sensors report battery: 0 due to firmware quirk. Override
battery calculation using voltage via homeassistant value_template.
Also adds zigbee_sensor_stale alert for detecting dead sensors regardless
of battery reporting accuracy (1 hour threshold).
Device configuration moved from external devices.yaml to inline NixOS
config for declarative management.

NATS HTTP monitoring endpoint serves JSON, not Prometheus format.
Use the prometheus-nats-exporter which queries the NATS endpoint
and exposes proper Prometheus metrics.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add exporters and scrape targets for services lacking monitoring:
- PostgreSQL: postgres-exporter on pgdb1
- Authelia: native telemetry metrics on auth01
- Unbound: unbound-exporter with remote-control on ns1/ns2
- NATS: HTTP monitoring endpoint on nats1
- OpenBao: telemetry config and Prometheus scrape with token auth
- Systemd: systemd-exporter on all hosts for per-service metrics
Add alert rules for postgres, auth (authelia + lldap), jellyfin,
vault (openbao), plus extend existing nats and unbound rules.
Add Terraform config for Prometheus metrics policy and token. The
token is created via vault_token resource and stored in KV, so no
manual token creation is needed.

Update CLAUDE.md and README.md to reflect that secrets are now managed

The read-based loop split multiline values on newlines, causing only
the first line to be written. Use jq -j to write each key's value
directly to files, preserving multiline content.

Remove backup_helper_secret variable and switch shared/backup/password
to auto_generate. New password will be added alongside existing restic
repository key.

Replace sops-nix secrets with OpenBao vault secrets across all hosts.
Hardcode root password hash, add extractKey option to vault-secrets
module, update Terraform with secrets/policies for all hosts, and
create AppRole provisioning playbook.
Hosts migrated: ha1, monitoring01, ns1, ns2, http-proxy, nix-cache01
Wave 1 hosts (nats1, jelly01, pgdb1) get AppRole policies only.

nix-cache01 regularly hits high CPU during nix builds, causing flappy
alerts. Keep the 15m threshold for all other hosts.

The step-ca serving certificate is auto-renewed with a 24h lifetime,
so it always triggers the general < 86400s threshold. Exclude it and
add a dedicated step_ca_serving_cert_expiring alert at < 1h instead.

Move nix-cache_caddy back to a manual config in prometheus.nix using the
service CNAME (nix-cache.home.2rjus.net) instead of the hostname. The
auto-generated target used nix-cache01.home.2rjus.net which doesn't
match the TLS certificate SAN.

Add homelab.monitoring NixOS options (enable, scrapeTargets) following
the same pattern as homelab.dns. Prometheus scrape configs are now
auto-generated from flake host configurations and external targets,
replacing hardcoded target lists.
Also cleans up alert rules: snake_case naming, fix zigbee2mqtt typo,
remove duplicate pushgateway alert, add for clauses to monitoring_rules,
remove hardcoded WireGuard public key, and add new alerts for
certificates, proxmox, caddy, smartctl temperature, filesystem
prediction, systemd state, file descriptors, and host reboots.
Fixes grafana scrape target port from 3100 to 3000.
