Hi

I am sending Crowdstrike Streaming data to Splunk in CEF format. Sample log pasted below
How do I get Splunk to recognize all the CEF fields from this stream?

host = 10.xx.130.xxx source = tcp:6514 sourcetype = cef_data_stream

There are TA and other Apps for Crowdstrike but I wasn't able to get it working. Splunk receives the logs correctly but isn't able to parse all CEF log fields correctly

It only parses following 3?

host = 10.xx.130.xxx source = tcp:6514 sourcetype = cef_data_stream.

Thanks!

We use Crowdstrike app which works perfectly fine (sending data on Test environment). The only CEF format i have used it in the past is from CyberArk. https://docs.splunk.com/Documentation/AddOns/released/CyberArk/Setup

You can refer the above document.
