If you plan to run federated searches that invoke your custom knowledge objects over a standard mode federated provider, identify the knowledge objects that you want to use in your searches and verify that they are present on the federated search head and the remote search head. Ensuring that custom knowledge objects are present on the local and remote search heads helps your federated searches to complete without errors and return correct results. Show
For example, if you are running a standard mode federated search that references a custom calculated field, the calculated field definition must be present on the local and remote sides of the federated search. If the calculated field doesn't exist on the remote search head, the remote search head can't apply the calculated field to search results from the federated provider. If the calculated field exists only on the remote search head, the search fails. Skip this topic if you are using a transparent mode federated provider. When you use transparent mode federated search, the Splunk software brings your local custom knowledge objects to the remote search head through automatic bundle replication. Example of a custom lookup in a standard mode federated searchSay you are using standard mode federated search, and you want to run a federated search that includes a custom CSV file-based lookup named empAddress. This lookup finds events in your search results with All CSV file-based lookups have two parts: a lookup definition, and a lookup table file. In this case, the lookup definition and lookup table file have the names empAddress and employee_addresses.csv, respectively. For this example, you run two searches. The first search applies the lookup to results from a remote index on the federated provider:
The second search applies the lookup to search results from an index on the local deployment as well as a remote index on the federated provider.
The following table tells you how these standard mode federated searches run, depending on the location of their lookup definitions and lookup table files. Location of lookup definition and lookup table fileResult of running the lookup search over a standard mode federated providerOnly on the local federated search head (FSH)The first search completes successfully but does not return results or error messages.The second search completes successfully, returning results only from the federated search head. It does not display error messages. Only on the remote search head (RSH)The Splunk software terminates both searches and displays error messages for them.Same definition and file exist on both the FSH and the RSHBoth searches succeed with results from both the FSH and the RSH.Before you run a standard mode federated search that involves a lookup, you must ensure that the lookup table file and lookup definition are duplicated on the local and remote sides of the search. If you are searching over multiple standard mode federated providers, you need to manually upload the same lookup table file to each federated provider, and you need to create identical lookup definitions on each federated provider. When you prepare to run federated searches with knowledge objects over standard mode federated providers, you can arrange for your searches to run without knowledge object errors by ensuring that there are knowledge objects with the same names on the local and remote sides of the search. However, if these identically-named local and remote knowledge objects have different definitions, this practice might cause your searches to return incorrect results. Improve your chance of getting correct results from a standard mode federated search that involves knowledge objects by duplicating the definitions of those knowledge objects on the local and remote search heads. When the knowledge object definitions and related files (such as CSV files, for CSV file lookups) are in sync on the local and remote sides of the search, you get consistent search results. Ensure a custom knowledge object exists on federated and remote search headsAfter you identify the custom knowledge objects that you are using in your federated searches, make sure those knowledge objects are present on the federated search head as well as the remote search head on the federated provider. In most cases the easiest way to do this is through Splunk Web. Prerequisites
Steps
Repeat this process for each knowledge object you intend to use in your federated searches. Help with knowledge objectsThe following table lists knowledge object definitions, files, and collections that you must duplicate on your federated and remote search heads if you want to use them in federated searches. You can verify the existence of a knowledge object by looking it up in Settings for your local deployment and the remote deployments involved in the federated search. Who can share knowledge objects Splunk?Basically, if you're using Splunk, you're using one very large knowledge object. With those knowledge objects, you can share them with other Splunk users, and include tags, events, reports, and alerts to organize and maintain your data. There are several types of knowledge objects.
When a user has left your organization what happens to their knowledge objects in Splunk?When a knowledge object owner leaves a department or company and their Splunk account is deactivated, the knowledge objects that they owned remain in the system. These are orphaned knowledge objects.
What are the three predefined sharing options for a knowledge object in Splunk?(A) They are automatically reassigned to an admin. (B) A power user can reassign them to another user. (C) They are automatically reassigned to a power user.
Where are knowledge objects stored in Splunk?Splunk Web saves configuration settings by creating a local copy of the file, as follows: Knowledge objects for your app are saved in the $SPLUNK_HOME/etc/apps/appname/local or $SPLUNK_HOME/etc/username/appname/local directory, depending on permission settings.

Splunk by default, when a knowledge object is created, who can access its contents?
