Does this tool aim for supporting querying the instantaneous EMR usage stats regarding the moment of making the query, or for any time point? As to the output, could you provide more formats? For example, it outputs by default json-typed data (which facilitates chaining the output to other programs) but it may output in a human friendlier format if given "--pretty-output" option. |

Could you add more specifics about the functionalities, e.g., what are the EMR stats? what is the definition of "active"?
