What statistical function provides the count of unique values in Splunk?

1. sum

2. distinct_count

3. values

4. avg

The correct answer is: distinct_count

The count of unique values in Splunk is determined by the function "distinct_count." This function is specifically designed to analyze a field in your dataset and return the number of unique values present. It is particularly useful when you want to understand the diversity or variety of data entries within a field, such as counting how many unique users accessed a system, or identifying distinct event types within logs. The other functions serve different purposes. "sum" is used for calculating the total of numeric values, while "avg" computes the average of numeric values. The "values" function returns a list of unique values but does not provide a count of them. Distinct counting is crucial for data analysis tasks where knowing the variety within a dataset can lead to better insights.
