The timestamp looks like "2017-02-06 04:01:12,757" and the pattern I chose is %{DATESTAMP:timestamp}. But when the parsing occurs , the timestamp is converted as 0017-02-06T10:42:24.923Z and it is causing issues while creating timestamp based indexing "logstash-0017.02.06" Can anyone assist me in identifying the correct pattern or am I using it wrong? Thanks, Harsha ---

I solved it . I tried TIMESTAMP\_ISO8601 and worked well. Thanks ---
