![]() ![]() A subsearch is a search within a primary or outer search. They are full searches that produce separate sets of data that will be merged to get the expected results. It is important to note that the searches specified in square brackets above are not actual subsearches. Since multisearch is a generating command, it must be the first command in your SPL. Results from the multisearch command are interleaved, not added to the end of the results as with the append command. ![]() This could save you some runtime especially when running more complex searches that include multiple calculations and/or inline extractions per data source. One major benefit of the multisearch command is that it runs multiple searches simultaneously rather than sequentially as with the append command. It requires at least two searches and should only contain purely streaming operations such as eval, fields, or rex within each search. Multisearch is a generating command that runs multiple streaming searches at the same time. You can see that the append command just tacks on the results of the subsearch to the end of the previous search, even though the results share the same field values. The last four rows are the results of the appended search. – It can only run over historical data, not real-time dataĮxample: In the example below, the count of web activities on the Splunk User Interface is displayed from _internal index along with count per response from the _audit index.– The secondary search must begin with a generating command.– Subject to a maximum result rows limit of 50,000 by default.– Displays fields from multiple data sources.They are run at the point they are encountered in the SPL. It is important to also note that append searches are not processed like subsearches where the subsearch is processed first. Note that the secondary search must begin with a generating command. After the append, you can use the table command to display the results as needed. The results from the append command are usually appended to the bottom of the results from the primary search. ![]() Does not allow calculations or manipulations per source, so any further calculations or manipulations will need to be performed on all returned eventsĮxample: In the example below, the OR operator is used to combine fields from two different indexes and grouped by the customer_id, which is common to both data sources.Īppend is a streaming command used to add the results of a secondary search to the results of the primary search.
