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.
