I am trying to parse "20170201 00:54:24 GMT-0600" field from logline and convert it to the @timestamp. I designed a data filter which looks like this "YYYYMMDD HH:mm:ss zZ" but the output becomes 2017-01-01T07:02:01.000Z...can someone please assist me with this?
date {
match => ["SetupTimestamp", "YYYYMMDD HH:mm:ss zZ"]
locale => en
}
