regex to extract date from the file name

[athorat]

Hi

we are using fs_notification and monitoring a specific path.
I have a field called path which has the following values.
Now I have to extract the date from the name of the file which is 2016-03-28 for the following files and then do a count of those values.

This should get you the date

rex "_(?<date>\d{4}-\d{2}-\d{2})-"

I'm definitely not the best with regex, but maybe something like this?

rex field=path "\_\w+\_(?<date>\w+-\w+-\w+)"
