Logstash format for date format Dec 04 21:24:03.238 2018

Elastic Stack Logstash

Currently my log file contains the date format in Dec 04 21:24:03.238 2018 and the loglines are being tagged as dateparsefailure. Following is the date filter i have added in my logstash conf

date{
match => ["LogDateTime","yyyy-MM-dd HH:mm:ss","MMM dd hh:mm:ss.SSS yyyy","MM/dd/yyyy hh:mm:ss.SSS aa", "yyyy-MM-dd HH:mm:ss,SSS", "yyyy-MM-dd HH:mm:ss.SSS"]
timezone => "Asia/Kolkata"
target => "@timestamp"
}

Any idea why this is being tagged as dateparsefailure ???

It looks like this pattern should match that date format.
Try removing all other patterns and just use this one.

Thanks Andy for the reply. You were right the pattern you mentioned matched but it should contain HH instead of hh. I did the change and looks like it worked. Will keep you posted if the problem appears again.

ARgh! Of course!
Glad you found it :slight_smile:
