crawler-alert.py --metrics (5-minute timer) reads what the Traefik
access log gained since the last run, judges every request that names
an AI bot exactly like the weekly report (vendor IP ranges, forward-
confirmed rDNS, Meta's ASN) and writes cumulative counters to the
node_exporter textfile directory. Verdicts are cached per bot and IP
for a week, so DNS only sees new addresses; range files are refetched
once a day. It covers every router, while the mails keep watching
Forgejo only.
New dashboard "AI crawlers", and a row of it on the overview.
The overview's load gauge divided node_load1 by a count with fewer
labels, which matches nothing; aggregate both sides by host.

Nothing watched the servers: tonight's asxpio crash loop was found by
hand. On asxpio-ops, Prometheus (30 days), Loki (14 days) and Grafana
at gf.asxp.io (WireGuard only), with blackbox_exporter probing every
service from outside and postgres_exporter. On both hosts node_exporter
and cAdvisor on the VPC address, and Alloy shipping container logs, the
journal and Traefik's access log to Loki over the VPC.
Traefik and Forgejo expose their metrics; restic and the bucket replica
record their last success for node_exporter. Dashboards: an overview as
home, plus hosts, containers, Traefik, probes, Postgres and logs.
Alerts by email to me@asxp.io: host or service down, certificate under
14 days, disk or memory nearly full, a container restart-looping,
Postgres down, backup or replica stale.
