Convert the @timestamp field

Saravana37 · May 25, 2021, 7:56am

Hello All ,

I am trying to convert the @timestamp field to the required format.
@timestamp shows the field as : 2021-05-25T07:34:08.137Z and I want the value to be converted in to this format : 05/25/2021 07:34:08 . I have tried the below date filter format.
date { match => [ "@timestamp", "MM/dd/YYYY HH:mm:ss", "YYYY-MM-ddTHH:mm:ss.sssZ", "ISO8601" ] }

And the error shows as below. Please help.

You need to quote literal characters

"YYYY-MM-dd'T'HH:mm:ss.sss'Z'"

Hello @Badger ,

Thank you so much for your response. I am trying to convert the @timestamp field and getting _dateparsefailure . I tried with both below code but no luck. Please help.

date { match => [ "@timestamp", "MM/dd/YYYY HH:mm:ss", "YYYY-MM-dd'T'HH:mm:ss.sss'Z'", "ISO8601" ] }

also tried ,

date { match => [ "@timestamp", "MM/dd/YYYY HH:mm:ss", "MMM dd, YYYY @ HH:mm:ss.sss", "ISO8601" ] }

Thanks Again

Badger · May 26, 2021, 2:24pm

Your [@timestamp] field is already a date. Why are you trying to parse it again?

Saravana37 · May 27, 2021, 12:41pm

I want to print it in the required format . How can i do that ?

Badger · May 27, 2021, 3:28pm

elasticsearch stores a date as a long (milliseconds since the epoch). kibana formats this. You can reconfigure kibana to format it differently.

If you want to store it in elasticsearch as a string with a different format then use ruby and strftime.
