Hi , I have specific log in a file log: Tue May 2 03:54:22 2017 I use a grok filter to extract the timestamp into a field of its own called "datestamp" "datestamp" => "Tue May 2 03:57:00 2017 ", "@timestamp" => 2017-05-15T14:25:05.490Z, My filter here , {filter { date { match => ["datestamp" ,…

It looks like you have a trailing space in the datestamp field, which is not accounted for in the pattern. Correct the pattern used to extract this field and I do not see why it would not work.

I'm pretty sure it said a lot more than that. To save everyone's time, please copy/paste the command you're running and the full output you get.
