[Reference:, Splunk Documentation: Drilldown actions in dashboards, , , , Thestatscommand in Splunk is used to perform statistical operations on data, such as calculating counts, averages, sums, and other aggregations. When working with accelerated data models or report acceleration, Splunk may generate summaries of the data to improve performance. These summaries are precomputed and stored to speed up searches., Thesummariesonlyargument in thestatscommand controls whether the search should use only summarized data (summariesonly=true) or include both summarized and non-summarized (raw) data (summariesonly=false). By default,summariesonlyis set tofalse., Question Analysis:, The question asks what happens when you use thestatscommand withsummariesonly=false. Let's analyze each option:, A. Returns results from both summarized and non-summarized data.This is the correct answer. Whensummariesonly=false, Splunk includes both summarized data (if available) and raw data in the results. This ensures that all relevant data is considered, even if some data has not been summarized yet., B. Returns results from only non-summarized data.This is incorrect. Settingsummariesonly=falsedoes not exclude summarized data; it includes both summarized and non-summarized data., C. Returns no results.This is incorrect. Thestatscommand will always return results unless there is an issue with the query or no data matches the search criteria. Settingsummariesonly=falsedoes not cause the search to return no results., D. Prevents use of wildcard characters in aggregate functions.This is incorrect. Thesummariesonlyargument has no effect on the use of wildcard characters in aggregate functions. Wildcard behavior is unrelated to this setting., Why Option A Is Correct:, Whensummariesonly=false, Splunk combines summarized data (from accelerated data models or report acceleration) with raw data to ensure completeness. This is particularly useful in scenarios where:, Not all data has been summarized yet., You want to ensure that your results are comprehensive and include the latest data that may not yet be part of the summary., For example, consider a scenario where you have an accelerated data model summarizing logs for the past 30 days. If you run a search withstats summariesonly=false, Splunk will include both the summarized data (for the past 30 days) and any new, non-summarized data (e.g., logs from today)., , | stats count by sourcetype summariesonly=false, , , In this example:, If summaries exist for some data, they will be included in the results., Any raw data that has not been summarized will also be included., The final output will reflect the combined results from both summarized and non-summarized data., Key Points About summariesonly:, Default Behavior:The default value ofsummariesonlyisfalse, meaning both summarized and non-summarized data are included by default., Use Case for summariesonly=true:If you want to restrict the search to only summarized data (e.g., for faster performance), you can setsummariesonly=true., Impact on Results:Usingsummariesonly=falseensures that your results are complete, even if some data has not been summarized., References:, Splunk Documentation - stats Command:https://docs.splunk.com/Documentation/Splunk/latest/SearchReference/statsThis document explains thestatscommand and its arguments, includingsummariesonly., Splunk Documentation - Data Model Acceleration:https://docs.splunk.com/Documentation/Splunk/latest/Knowledge/AcceleratedatamodelsThis resource provides details about how data model acceleration works and the role of summaries in accelerated searches., Splunk Core Certified Power User Learning Path:The official training materials cover the use of thestatscommand and its interaction with summarized data., By ensuring that both summarized and non-summarized data are included,summariesonly=falseprovides the most comprehensive results, makingOption Athe verified and correct answer., , , , ]
