# garage-pdu-relay: expose APC AP7830 metered output current via snmpd extend.

# Relay pattern (founder ruling 2026-09-02): the garage PDU speaks SNMPv1
|

# only, walks die on its old AOS, and its ACL admits the LibreNMS VM vantage.
|
|
# This relay runs ON tsys-librenms; HA polls the relay via the fleet snmpd
|
|
# extend (same rails as drac-extend). Output: "output_amps <x.y>".
