Quick Answer
The answer is `accum` and `streamstats`. Both commands calculate a running total, or cumulative sum, of a numeric field across ordered events, but they achieve this differently: `accum` adds each event’s value to a running total based strictly on the current search result order, while `streamstats` offers more flexibility by allowing you to define a window or reset conditions for the cumulative sum. On the Splunk SPLK-1003 exam, this concept tests your understanding of event-processing commands that depend on result order, a common pitfall being that `accum` requires no additional options for a simple running total, whereas `streamstats` needs the `current=true` and `window=0` parameters to mimic the same behavior. A helpful memory tip: think of `accum` as “accumulate in place” for a straightforward running total, and `streamstats` as “streaming statistics” for when you need to control the calculation window.
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 search commands can be used to calculate a running total (cumulative sum) of a field over time?
delta
Why wrong: Computes differences between consecutive events, not cumulative sum.
accum
Built-in command for cumulative sum.
transaction
Why wrong: Groups events into transactions, does not compute running total.
streamstats
Can compute running sum using a window function.
eventstats
Why wrong: Adds summary statistics but not running totals.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
accum
B is correct because the `accum` command calculates a cumulative sum of a specified numeric field across all events in the search result order, adding each event's value to the running total. This directly implements a running total without requiring any additional options.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
delta
Why it's wrong here
Computes differences between consecutive events, not cumulative sum.
accum
Why this is correct
Built-in command for cumulative sum.

eventstats
Why it's wrong here
Adds summary statistics but not running totals.
Common exam traps
Splunk often tests the distinction between `accum` and `eventstats`, where candidates mistakenly choose `eventstats` thinking it computes running totals, but it actually computes a single aggregate over all events and appends that same value to every event.
Detailed technical explanation
The `accum` command works by maintaining an internal accumulator that adds the current event's field value to the previous total, outputting the running sum in a new field. In contrast, `streamstats` can also calculate cumulative sums using the `sum` function with the `current=true` option, making it another valid choice. A subtle behavior is that both commands respect the order of events as returned by the search, so sorting by time is critical for accurate running totals.
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.
