SPLK-1002 Transactions and Event Correlation Practice Question
A team wants to correlate events from different sourcetypes (web, db) on a common `sessionid`. They use `transaction sessionid` across both sourcetypes. The results show that some transactions are missing events. What is the most likely cause?
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
✓
Timestamps from different sourcetypes are misaligned
Sourcetypes may have different timestamp formats or time zones, causing events to be incorrectly sorted out of the transaction window. Option C (maxevents) would truncate but not miss events. Option D (field name) is unlikely. Option A (search time level) is not relevant.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The search is running at 'info' level instead of 'verbose'
Why it's wrong here
The search running at 'info' level instead of 'verbose' does not affect event correlation; it only changes the verbosity of search results. This would not cause missing events in transactions.
- ✓
Timestamps from different sourcetypes are misaligned
Why this is correct
Correct. When sourcetypes have different timestamp formats or time zones, events may be incorrectly ordered or fall outside the default transaction window, causing some events to be missing from the transaction.
- ✗
maxevents is set too low
Why it's wrong here
Setting maxevents too low would limit the number of events per transaction, but it would not cause events to be completely missing across transactions. The issue described is about missing events entirely, not truncation.
- ✗
sessionid field has different names in each sourcetype
Why it's wrong here
If the sessionid field had different names, the transaction command would not match events at all. The stem states they use a common sessionid, so this is not the cause.
