Please say more about what you want to do. Do you want to use the rex command inside a datamodel or use the rex command on the results returned by a DM?
If the former then you don't need rex. When you add a field to the DM, choose "regular expression" and enter your regex string. The fields you define in the regex (using named capture groups) will become fields in the DM.
If the latter then, yes, you can.
Be aware that more fields in a DM equates to more storage needed to store the results if the DM is accelerated.
Hello @richgalloway
thanks for your reply
yes, im referring to the second option.
can you show me an example of how can i do it ?
thanks
One you have results from the datamodel, use the rex command on those results the same way you would use it on any other result set. You will not have a _raw field so the rex command must specify a field name
yeah, so, i need the rex to run with _raw
for example :
rex field=_raw "TTY=(?<dstuser>.*) ; PWD=(?<url>.*); USER=(?<srcuser>.*) ; COMMAND=(?<status>.*)" | where isnotnull(dstuser)
what replacing the _raw after the datamodel is working ?
