Getting timestamp of event from file name in logst

问题:

We have a process that writes events to a file, without a timestamp. The file names themselves are suffixed with a timestamp, which is the timestamp that should be used for all the events in the file. Now, I am trying to parse the file by using the input file plugin of logstash. Is there a way by which I could get the name of the file to a field, so that I can then use the gsub filter to extract out the timestamp and then use the date filter to set the timestamp to the event?

I had a similar need, and asked this question again - so you can find a more up-to-date answer in this question thanks to Jettro Coenradie :)
