How to write the regex to extract the error code from my sample log?

How can I find all the error codes from the logs and show it as interesting field?
e.g. Message : Information with Insured. (PL200XXX)
Here PLXXXXX is the error code within the parentheses. What regex or search criteria should I use to make this work? I am new to Splunk and exploring it.

Thanks a lot for your help.

Try:
If the error code always starts with PL and there are other values between ( ) in your data.
.. | rex "\((?<err_code>PL\w+)\)"

Good Luck!

This one is pretty simple.

sourcetype=yoursourcetype | rex field=_raw "\((?<errorcode>[^)]+)\)"

This should give you the results you want in errorcode. This is a very quick regex - if you are going to make it "production ready", don't use rex, use the props/transforms to pull it automatically.
