- A
timechart count by status | eventstats sum(count) as total by _time | eval pct = round(count/total*100,2) | chart first(pct) over _time by status
This correctly computes percentages per time bucket and presents them in a time series.
- B
chart count by status over _time | eval pct = count / sum(count) * 100
Why wrong: The chart command aggregates at the same time as the eval, but sum(count) gives overall total across all time, not per day.
- C
timechart count by status | addtotals | eval pct = count / total * 100
Why wrong: addtotals adds a column of overall total, not per-day total.
- D
timechart count by status | append [timechart count] | eval pct = count / [| timechart count] * 100
Why wrong: Subsearches are inefficient and not designed for per-bucket calculations.
Quick Answer
The answer is Option A, which uses timechart count by status followed by eventstats and eval, because this pipeline efficiently calculates the percentage of total HTTP status codes per day by first aggregating counts per time bucket, then using eventstats to compute the daily total per _time, and finally applying eval to derive the percentage. This approach is the most efficient for calculating percentage per day with timechart and eventstats, as it avoids subsearches or redundant commands while keeping the data in a single search stream. On the Splunk Core Certified Power User SPLK-1003 exam, this question tests your ability to combine transforming commands with eventstats for per-row calculations within time-based results—a common trap is confusing eventstats with stats, which would collapse the time dimension. Remember the memory tip: "timechart counts, eventstats totals, eval percentages" to keep the pipeline order straight.
SPLK-1003 Advanced Visualization and Lookups Practice Question
This SPLK-1003 practice question tests your understanding of advanced visualization and lookups. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An analyst needs to create a time-series chart showing the percentage of total HTTP status codes per day. Which approach is most efficient?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
timechart count by status | eventstats sum(count) as total by _time | eval pct = round(count/total*100,2) | chart first(pct) over _time by status
Option A is correct because using timechart to get counts by status, then eventstats to compute total per day, and eval to calculate percentage, is efficient and clear. Option B is incorrect because using chart with a single stats command cannot compute percentages across groups per time bucket. Option C is incorrect because addtotals adds overall totals but does not compute per-day percentages. Option D is incorrect because overcomplicates with subsearches.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✓
timechart count by status | eventstats sum(count) as total by _time | eval pct = round(count/total*100,2) | chart first(pct) over _time by status
Why this is correct
This correctly computes percentages per time bucket and presents them in a time series.

- ✗
chart count by status over _time | eval pct = count / sum(count) * 100
Why it's wrong here
The chart command aggregates at the same time as the eval, but sum(count) gives overall total across all time, not per day.
- ✗
timechart count by status | addtotals | eval pct = count / total * 100
Why it's wrong here
addtotals adds a column of overall total, not per-day total.

Why it's wrong here
Subsearches are inefficient and not designed for per-bucket calculations.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
