The answer is to use `| eval day=if(_time>=relative_time(now(),"@d"),"today","yesterday") | timechart count by user by day`. This works because the `eval` command dynamically labels each event as "today" or "yesterday" based on whether its timestamp falls after the current day's midnight, and then `timechart` with the `by user by day` clause splits the count into separate columns for each day and each user. On the Splunk Core Certified Power User SPLK-1003 exam, this tests your ability to combine `eval` with relative time functions and `timechart` for side-by-side comparisons—a common trap is trying to use `timechart` with a static time range or `useother`, which won't create the desired columns. A helpful memory tip: think of `relative_time(now(),"@d")` as "snapping to today's start," and the `if` statement as a simple gatekeeper that sorts your data into two buckets before the chart splits them.
SPLK-1003 Advanced Searching and Statistics Practice Question
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.
A security analyst wants to create a comparison report showing the count of login failures by user for today versus yesterday. They run: `index=security action=failure | timechart count by user`. This produces a chart of counts over time, but they want separate columns for today and yesterday. How can they achieve this comparison efficiently?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use `| eval day=if(_time>=relative_time(now(),"@d"),"today","yesterday") | timechart count by user by day`.
Using `eval` to create a day label and then `timechart` with the user and day fields creates the desired side-by-side chart. Option A is incorrect because timechart does not have a 'useother' option for this. Option C works but is less efficient and may require manual time ranges. Option D does not produce a time-based comparison.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use `| append [search index=security action=failure earliest=-2d@d latest=-1d@d | eval period="yesterday"] | timechart count by user by period`.
Why it's wrong here
Works but is more complex and less efficient than the eval approach.
✓
Use `| eval day=if(_time>=relative_time(now(),"@d"),"today","yesterday") | timechart count by user by day`.
Why this is correct
Correctly categorizes events by day and creates separate columns.

Read the scenario before looking for a memorised answer.
✗
Use `| stats count by user _time | xyseries _time user count`.
Why it's wrong here
This creates a matrix over time, not a direct today vs yesterday comparison.
✗
Use `| timechart count by user useother=t` with the time range set to 'Yesterday' and 'Today' in the time picker.
Why it's wrong here
useother is not a valid timechart parameter for comparing time ranges.
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.

Variation 1. An analyst wants to create a time-series comparison of the current week and the previous week. Which TWO commands are commonly used together to achieve this? (Select two.)
medium
A.stats
✓ B.timechart
C.eventstats
✓ D.timewrap
E.appendcols
Why B: B is correct because `timechart` is the primary command for creating time-series aggregations, allowing you to split data into time buckets and apply statistical functions. D is correct because `timewrap` is specifically designed to compare time periods (e.g., current week vs. previous week) by wrapping the time-series data into separate series for each period, enabling side-by-side visualization.
