Hi, I am trying to use the custom command to read the data from other database and return to Splunk as query results. I understand that a custom command can be developed in python script and I'm thinking that python script can read the data from the database and return to Splunk.  I have few questions here:  When we execute the custom search command in Splunk search GUI - does custom search command requests goes to Indexer?  In other words, do I need the indexers when i just run only the custom search command in my Splunk distributed environment? The custom search command had to retrieve lots of data from database. So, the custom search can be used for large volume of databases and performance issues can be anticipated for custom search commands?  How Splunk handles the custom search commands in backend - when there are multiple users execute the custom search command - Splunk executes the python script in the same thread (or) in different thread per user search request?   Thanks ...

Hi,  My CSV(test_csv_lookup) looks like this:  --- index; value 1, 1.1.1.1 ---- here is my automatic lookup  LOOKUP-field_extract = test_csv_lookup index AS ip OUTPUTNEW value AS lookedup_val   I have two following events in the index for which I will apply the the above automatic lookup:  event1 -  timestmap, 1 event2 - timestmap, 2.2.2.2.    In above event, the "ip" field values are "1", and "2.2.2.2", in the first event, "1" being the value of the "ip" ,  just refers to the index value of the lookup table and second event just contain raw value, and doesn't need lookup.  When I query for the index, the lookedup_val  shows the "1.1.1.1". What I need is that, both the values(in the fieldlookedup_val) , that is "1.1.1.1" and "2.2.2.2".  For the first event, its working fine, by looking up the index and able to retrieve, for the second event also it's doing the lookup and obviously it can't find.  When lookup can't find the value, could it' use the raw value or default field value, in this case, 2.2.2.2? Is there a way I can specify this in automatic lookup output? Thanks,         ... View more

Hi, SSE use case maps to the MITRE ATT&CK tactics. As we can see from MITRE ATT&CK, each tactic has various techniques. For "Data Exfiltration" , the techniques are "Data Transfer Size Limits" , "Exfil over Alternate Protocol" etc. For example: In SSE, the example "Sources Sending a High Volume of DNS Traffic" mapped to MITRE ATT&CK's DataExfiltration. Splunk reports outliers. How do I know which technique splunk used to determine the outlier? Or Splunk doesn't use any of these techniques , it just uses the total bytes transferred and looking for anomalies and deviations from normal traffic levels.? Thanks, Mahesh ... View more
