What does the command `tstats` do in Splunk?

The command tstats in Splunk is specifically designed to facilitate fast statistical queries on indexed data. This command leverages the summary indexing feature, which allows it to operate efficiently by reading from pre-computed summary indexes instead of the raw event data. This optimization results in significantly better performance, especially for large datasets, as it reduces the amount of data that needs to be processed in real time.

Using tstats, users can perform aggregations, statistical calculations, and generate insights much quicker compared to traditional search methods. Because it operates on indexed data, it can provide quicker response times and handle higher query loads, making it ideal for applications that require frequent statistical analysis of significant volumes of data.

The other choices refer to functionalities that are not part of what tstats does. Generating alerts relates to monitoring conditions within data rather than executing statistical queries, archiving entails storing data over time, and visualizing real-time data flows involves different commands and methodologies within Splunk focused on data presentation rather than on query performance.
