Quick Answer
The correct answer is eventstats and streamstats, as both commands perform statistical aggregations on streaming events without creating a separate search results set. Eventstats computes overall aggregations—like sums or averages—across the entire event set and appends the result as a new field to each existing event, while streamstats calculates windowed statistics in real-time as events arrive, such as running totals or moving averages, also adding the output directly to each event. On the Splunk SPLK-1003 exam, this distinction tests your understanding of how these commands differ from stats, which does create a separate table; a common trap is confusing streamstats with eventstats by forgetting that streamstats processes events sequentially and can use a window parameter. To remember, think of eventstats as “entire set stats” and streamstats as “streaming, step-by-step stats.”
This SPLK-1003 practice question tests your understanding of advanced searching and statistics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO commands can be used to perform statistical aggregations on streaming events without creating a separate search results set?
timechart
Why wrong: timechart creates a time-based chart, not streaming.
stats
Why wrong: stats creates a new summary table, not streaming.
streamstats
streamstats adds stats to each event as the results stream, preserving all events.
eventstats
eventstats adds stats to each event in the existing results.
chart
Why wrong: chart creates a new table, not streaming.

Correct answer & explanation
streamstats
C is correct because streamstats performs statistical aggregations on streaming events in real-time as they arrive, without creating a separate search results set. It computes windowed statistics (e.g., running sum, moving average) on the event stream itself, appending the result to each event. D is correct because eventstats also operates on the current event set, computing aggregations and adding the results as new fields to each event without generating a separate output set.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Splunk often tests the distinction between commands that produce a new results set (stats, chart, timechart) versus those that augment the existing event stream (streamstats, eventstats), and the trap here is that candidates confuse eventstats with stats, thinking both create separate outputs.
Detailed technical explanation
Under the hood, streamstats uses a sliding window (default size 0, meaning cumulative) to compute running aggregations like sum, average, or count, and appends the result to each event as a new field. eventstats performs a non-streaming aggregation across the entire event set (or by group) and then joins the result back to each event, which can be memory-intensive for large datasets. A real-world scenario: using streamstats to calculate a running total of sales per user in real-time, while eventstats might compute the average sales per user and add that value to each event for comparison.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the SPLK-1003 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
