Seeking your help on the issue that i've encountered. see logstash logs

Thank you

You have an index template that says the [@timestamp] field has to be in the epoch_millis format, but you are sending it an ISO8601 format. I suggest you change your index template.

Thank you for the response. Will have this try.

Thank you. :slight_smile:
