grok {
 match => { "message" => "%{TIMESTAMP_ISO8601:Time} %{ISO8601_TIMEZONE} %{GREEDYDATA:Message}" }

elasticsearch expects the [Time] field to be a date. Either you have a mapping that tells it that, or it has previously decided that using dynamic mapping.

The date parser defaults to strict_date_optional_time or epoch_millis.

strict_date_optional_time is "A generic ISO datetime parser, where the date must include the year at a minimum, and the time (separated by T), is optional. Examples: yyyy-MM-dd'T'HH:mm:ss.SSSZ or yyyy-MM-dd."

So you can use mutate+gsub to change the " " to "T" in "2021-03-17 10:27:00.115", or else use a date filter to parse the field and overwrite it, in which case the elasticsearch output will send it to elasticsearch in an appropriate format.

I added below config.
It work.


mutate {
   gsub => [ "Time", " ", "T" ]

Thank you for your advise.
