## gNMI targets — driven by environment variables so the telemetry fleet can
## scale without editing this file. Set in .env:
##   GNMI_ADDRESSES — quoted, comma-separated host:port list, e.g.
##     GNMI_ADDRESSES="10.0.0.1:57400", "10.0.0.2:57400"
##   GNMI_USERNAME / GNMI_PASSWORD — gNMI credentials (uniform across the fleet)
## Every target must have gNMI/grpc enabled and be reachable on the gRPC port.
