What is the correct way to name a macro with two arguments?

The correct way to name a macro with two arguments is "us_sales(1,2)". When defining macros in Splunk, the naming convention allows for parentheses to be used to specify the number of arguments that the macro can accept. The parentheses are essential as they clearly delineate the macro name from its parameters.

The correct choice indicates that the macro "us_sales" is capable of accepting two arguments, labeled as "1" and "2". This format helps in identifying how many inputs the macro is designed to handle, thus ensuring proper functionality when being referenced in searches or commands.

Using just "us_sales(2)" implies only a single argument, as the number represents one input. The choice "us_sales,2" uses a comma, which is not a valid syntax for naming a macro as it deviates from the expected format. While "us_sales2" could be interpreted as a name of a macro, it does not signify the presence of two arguments, as it lacks the necessary parentheses. Hence, this correct format of "us_sales(1,2)" is crucial for proper macro creation and usage within Splunk.
