Splunk Core Certified User High-Yield Scenarios¶

Scenario 1: A search returns nothing for one analyst¶

Scenario: A search works for one colleague and returns no events for another, using the same words and time range.

Solution Pattern: - Check the role of the second user: roles limit which indexes can be read - Check that the search names the index; the default indexes differ by role - Check the time range and the user's time zone setting

Key Takeaway: Missing results are usually access, index or time, not the data.

Scenario 2: Stats shows fewer rows than expected¶

Scenario: A stats count by host, status search seems to be missing hosts.

Solution Pattern: - Events lacking any by field are left out of the result - Check that both fields exist on the events, for example with status=* - Use fillnull or fix the extraction if values are missing

Key Takeaway: A by clause silently drops events missing the field.

Scenario 3: Count of users is too high¶

Scenario: A manager asks how many different users logged in, and stats count returns the number of log lines.

Solution Pattern: - Count distinct values with dc(user) - Use values(user) to see the list of unique users

Key Takeaway: count counts events; dc counts different values.

Scenario 4: A chart will not draw¶

Scenario: A user wants a pie chart of errors by host from a plain search for errors.

Solution Pattern: - Add a transforming command, for example stats count by host - The Visualization tab then offers the pie chart - Save the report while that tab is showing

Key Takeaway: Charts need a results table, which needs a transforming command.

Scenario 5: A lookup does nothing¶

Scenario: A new CSV lookup was uploaded, but a search using it adds no fields.

Solution Pattern: - Confirm a lookup definition exists, not just the file - Check sharing on both the file and the definition - Confirm the input column name matches the event field, using AS if the names differ - Remember matching is case sensitive by default

Key Takeaway: File, then definition, then permissions, then field names.

Scenario 6: The alert emails every five minutes¶

Scenario: A failure alert is accurate but floods the team while the problem is being fixed.

Solution Pattern: - Turn on throttling for a suitable period - Optionally throttle per host or per value of a field - Consider triggering once, not for each result

Key Takeaway: Throttling suppresses repeats after the first firing.

Scenario 7: A dashboard panel does not follow a report change¶

Scenario: An engineer edits a saved report, but the dashboard panel still shows the old search.

Solution Pattern: - Check whether the panel was created from an inline search, which is its own copy - A panel that references the report picks up edits - Recreate the panel from the report if it should stay linked

Key Takeaway: Inline-search panels are copies; report-based panels stay linked.
