SPLK-1002 Transactions and Event Correlation Practice Question

An administrator runs a transaction command that groups events by a customer ID but notices that some transactions are missing expected events. The log shows that the events are present and within the maxpause. What could be the reason?

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

Events are from different hosts or sources.

The transaction command, by default, groups events not only by the specified 'by' fields but also by host, source, and sourcetype. If events for the same customer ID originate from different hosts or sources, they are treated as separate transactions. This explains why some transactions are missing expected events despite the events being present and within the maxpause. Option A correctly identifies this common pitfall. Option B is incorrect because startswith and endswith define transaction boundaries and do not conflict here. Option C is incorrect because the 'fields' option is not required; without it, the default grouping includes host and source, which causes the issue. Option D is incorrect because the maxpause is explicitly stated to be adequate.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Events are from different hosts or sources.

    Why this is correct

    By default, transaction groups by host, source, and sourcetype; events from different hosts are not grouped.

  • The startswith and endswith are conflicting.

    Why it's wrong here

    Conflicting patterns would cause no transaction, not missing events.

  • The fields option is missing.

    Why it's wrong here

    fields is optional and does not affect grouping.

  • The maxpause value is too short.

    Why it's wrong here

    The log shows events are within maxpause, so that is not the issue.
