Hi There,

I have two fields date and time("10/26/20","09:30:53").
My Grok patterns are "%{DATA:date}","%{DATA:time}"

I would like to concatenate these two fields as datetime,
Could you please help me on the same.

You can use sprintf references

mutate { add_field => { "datetime" => "%{date} %{time}" } }
