![]() Subsearches contain an inner search, who’s results are then used as input to filter the results of an outer search. Simply put, a subsearch is a way to use the result of one search as the input to another. The filenames contain the source that we received the file from, and have a three digit sequence number as a suffix. J01:49 pm By: Brent Mckinney Splunk Consultant A subsearch in Splunk is a unique way to stitch together results from your data. If the search slots are available, multisearch should finish dramatically faster. Hi Folks, We receive several hundred files per day from 20 different sources. I think its value would come out in a case where you need to apply calculations (eval) or inline extractions (rex) to one set of events, but not to other sets of events, and it might make your search easier to understand (instead of getting multiple levels of if statements deep in your evals).Īdditionally, multisearch searches are run (more-or-less) simultaneously, not sequentially as they are with append. While in your simple example it might not have a benefit, multisearch lets you use any streaming command in each search. But one advantage is that from the append command, the multisearch command doesn’t do truncating, so without truncating you can append multiple data set using this multisearch command. This similarly works like append or appendcols command two combine two different data set together into one angel data set. In the result, you can see that we are getting data from both two indexes. [search index=_audit sourcetype=audittrailĪs you can see here we have used two sub searches and combined them with the multisearch command. ![]() [search index="_internal" sourcetype=splunkd_access These sub-searches will only contain the following commands where, search, rex, fields, and eval. It requires more than one sub-search to execute this command. ![]() Multiserach is a generating command (Generating commands use a leading pipe character and should be the first command in a search) that runs multiple searches at the same time without truncating the results of data sets. ![]()
