WHERE nodename=All_Changes.Account_Management.Accounts_Created Step 11: We are now ready to create the accelerated data model search using the tstats command. ![]() Step 10: Debug/refresh Splunk through the GUI to allow the configuration changes to take affect. Notice that the commented tags match the tags in the Created Accounts child object. I usually add the organization name to the beginning of the event type name. When copying the event type over, be sure to customize the event type. Step 8: In the nf file, copy the windows_account_created event type from the default nf file to the local nf file. Within the local folder, create an nf and a nf file. We will have to edit the default setting in a local folder. For this example, the tag(s) do not match. This means that the event type tag(s) must match the data model child object tag(s) in order to leverage the data model. The tag(s) is what connects the event type to the data model. Take notice of the constraints for the child object, specifically the tags (tag = change, tag = account). For this example, we will utilize the Created Accounts child object. Step 6: Identify the appropriate child object(s) within the selected data model. For this example, the Change Analysis data model can be used to fulfill our use case. Search through the CIM data models to find the data model that best matches the use case. Step 5: Through the Splunk GUI, go to Settings > Data models. Pay particular attention to how these event types are tagged. Search = sourcetype=*:Security (signature_id=4720 OR signature_id=4741 OR signature_id=624 OR signature_id=645) For this example, the event type below will fulfill our use case. Search the nf for any event types that may be useful to search for events involving user/computer account creation. For this example, the Splunk Add-on for Microsoft Windows will work for Windows data. Step 2: Search splunkbase for any existing Windows TAs. This means the data should be properly indexed, sourcetyped, etc. Step 1: Make sure Windows data is coming into Splunk according to best practices. This blog will go through an easy, cut through, step by step procedure on how to create a custom search while leveraging the CIM data model.Įxample Use Case: Monitor all Windows user/computer account creation. The above example uses the pattern=* attribute to show everything in the _internal index with a count of the number of occurrences in the buckets for a specific time range.Accelerated data models have made performing searches over large periods of time and/or large amounts of data extremely fast. term must be an event-generating command such as search, eventcount, or tstats (usually, youll use search. | walklex pattern=* type=fieldvalue index=_internal | stats sum(count) by term | walklex prefix=foo type=fieldvalue index=foo | stats sum(count) by term You can find more about using WalkLex in the SplunkWeb GUI from the Splunk documentation. The quotes at the end of the CLI command are the pattern or term you want to search for:.Add > filename.txt to the end of the command to create a text file to view a text editor./opt/splunk/bin/splunk cmd walklex “/opt/splunk/var/lib/splunk/_internaldb/db/bucket name/add_name_of.tsidx” “ ”Įxample of the WalkLex Command: /opt/splunk/bin/splunk cmd walklex “/opt/splunk/var/lib/splunk/_internaldb/db/DIR/FILESNAME.tsidx” “*”.cd /opt/splunk/var/lib/splunk/_internaldb/db/.How to utilize the WalkLex command in the CLI this allows for a specific warm or cold bucket inspection. WalkLex Command-line Interface (CLI) Example: The search then uses location references from the keywords to get events from the rawdata file. ![]()
