If the search slots are available, multisearch should finish dramatically faster. 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. If the join setting is misconfigured, the playbook may stop or run in ways that the analyst did not intend. Pro tip: parallel single actions are the culprit. When transitioning from more than one action block to a single block, some playbooks may stop running unexpectedly. While in your simple example it might not have a benefit, multisearch lets you use any streaming command in each search. That’s probably because of your ‘join’ settings. ![]() 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 This means event CW27 will be matched with CW29, CW28 with CW30, and so on. ![]() Events from the main search and subsearch are paired on a one-to-one basis without regard to any field value. These sub-searches will only contain the following commands where, search, rex, fields, and eval. 1 The appendcols command is a bit tricky to use. Use those ideas in creating a dashboard with at least 6 panels containing security information relevant to the BOTSv1 investigation. Think about data that would have been helpful to Alice Bluebird and the rest of the security operations team at Frothly. It requires more than one sub-search to execute this command. Splunks BOTSv1 data set has many different types of information available. I am trying to join data in one source to another join that joins two searches. ![]() 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.
