Hi you can use regex in correlation rule but you need a field based on string.
Thanks, I have tried but did not work, maybe I am doing something wrong?
When using this regex over the source name field, it does nothing
Can you tell me if this is the proper way to use regex?
you can not use regex on the field source user. Take a look und the fiel Message_Text than on the drop down (In, Not In Contains Regex). This field have the option for regex.
