How should metrics be passed using call arguments instead of standard input?

Passing each metric as a separate argument is the best approach when you want to ensure clarity and precision in metric handling. This method allows for distinct tracking and processing of each individual metric, making it easier to manage and analyze data. By treating each metric individually, you reduce the complexity of data ingestion, as each metric can be referenced and utilized separately within the system.

Furthermore, this approach allows for better performance and optimization since individual metrics can be evaluated and acted upon independently. When metrics are combined into one argument, it may lead to ambiguities and difficulties in parsing the data accurately later on. Therefore, using separate arguments facilitates better scalability and adaptability in your metrics processing strategy.
