Question 501 of 502
SPLK-1001 Using Fields and Lookups Practice Question
An analyst wants to compute the average response time for each server from web server logs. The field `response_time` is a string like '120ms'. What is the correct way to convert and compute?
⚠ Common exam trap
Many candidates assume `replace` alone makes a field numeric, forgetting that Splunk treats the result as a string until an explicit arithmetic operation (like `*1` or `tonumber()`) forces type conversion.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
eval response_num=replace(response_time, "ms", "") | eval response_num=response_num*1 | stats avg(response_num) by server
It first uses `replace` to strip the 'ms' suffix from the string field `response_time`, then multiplies the resulting string by 1 (`response_num*1`) to coerce it into a numeric type. Only after conversion can `stats avg(response_num) by server` compute a meaningful average. Without the numeric coercion, Splunk would treat the field as a string and either fail or produce incorrect results.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
eval response_time=response_time + "0" | stats avg(response_time) by server
Why it's wrong here
Adding a string does not convert to numeric; avg will fail.
- ✓
eval response_num=replace(response_time, "ms", "") | eval response_num=response_num*1 | stats avg(response_num) by server
Why this is correct
Replace removes 'ms', and multiplying by 1 converts to numeric, then avg works.
- ✗
eval response_num=replace(response_time, "ms", "") | stats avg(response_num) by server
Why it's wrong here
Replace returns a string, so avg will treat it as a string with unpredictable results.
- ✗
eval avg_response=avg(response_time)
Why it's wrong here
Avg requires numeric fields; string fields cause errors or unexpected results.
