# OPC DA Diagnozer — example configuration.
# Copy to config.yaml and adjust. Every threshold below is configurable
# (defaults live in src/opcda_diagnozer/config.py; rules in docs/SPECIFICATION.md §6).

# device. DOWN (= DEVICE_LINK_DOWN, CRITICAL, clear-text status in the log) when
# the tag reads non-GOOD, errors, or its GOOD value is NOT in ok_values.
# ok_values defaults to [true] (boolean connected-flags); set it per system
# convention: inverted fault flags -> [false, 0], string states -> ["RUN"].
# Compared by string equality on the rendered value ("True"/"1"/"RUN").
# Do NOT also list these under tags: - they are polled automatically.
