The rate_sum function is designed to return the summed rates of time series data associated with a specified metric in Splunk. It takes into account the individual rates of the time series for the selected metric and aggregates these rates over a defined time interval. This is particularly useful when analyzing metrics that are cumulative in nature, allowing users to understand the total volume or frequency of specific events over time.

Utilizing this function helps in performance monitoring and trend analysis, where you need to ascertain not just the individual rates but how these rates contribute cumulatively across a specified timeframe. By summing these rates, you can derive insights that indicate how various metrics behave during specific periods, aiding in capacity planning and performance troubleshooting.

On the other hand, while average values, individual values per second, and incremental changes are all useful concepts in data analysis, they do not accurately capture the specific outcome that the rate_sum function provides, which is fundamentally about aggregating rates within a time series context.
