I appreciate any any assistance with my Rex error.

When running this Rex command:

| rex "New Logon:\s+Security ID:\s+(?<account>.*)"

I receive the following error, "Rex in dashboard says missing terminator"

Thanks in advance!

That error message means the parser didn't understand the regular expression.  Usually, it's because a quotation mark was not escaped properly.  In this case, however, it's because the regex contains HTML-encoded < and > characters.  Unencode them and the rex should work.

Good morning Rich,

I appreciate your response, but I am not understanding your explanation " because the regex contains HTML-encoded < and > characters." as I do not see the < and > characters.

Could you highlight or modify the rex script with the proper syntax required for it to work correctly?

Cheers, Paul

You don't see the < and > characters because they are HTML-encoded.  IOW, change &lt; to < and &gt; to >.
