Usage

Configuration

fronius-exporter can be configured with CLI flags. Call the binary with --help to get a list of options.

💡	All flags are also configurable with Environment variables. Replace the . char with _ and uppercase the names in order for them to be recognized, e.g. --log.level debug becomes LOG_LEVEL=debug. CLI flags take precedence though.
