Hi, Could any one please help me getting the date from the timestamp using painless in the scripted field and group the data-set based on date,

doc['timestamp'].date.monthOfYear + '/' + doc['timestamp'].date.dayOfMonth + '/' + doc['timestamp'].date.year

I am trying to the get the count based on the date as below.

| | 11/17/2018 | 11/16/2018 | 11/15/2018 |
| --- | --- | --- | --- |
| Row1 | 10 | 25 | 333 |
| Row2 | 21 | 44 | 35 |
| Row3 | 22 | 11 | 24 |

Thanks.

@Dhana ,

that painless script looks correct, or am I missing something?

you can create a scripted-field with that script. [https://www.elastic.co/guide/en/kibana/current/scripted-fields.html](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html). You'll create a new string-field on the fly.

Then, you'll be able to do a terms-aggregation on that field and do a count by date.

Hi,

Thanks for confirming. So I can create a field name " test\_scripted\_field1" as string and use that for count.

Could you please verify the below configuration parameters and confirm.

Name - test\_scripted\_field1  
Language - painless  
Type - String  
Transform - none  
Popularity - 0  
Script  
doc['timestamp'].date.monthOfYear + '/' + doc['timestamp'].date.dayOfMonth + '/' + doc['timestamp'].date.year

Thanks,

yes that looks good I think.

you can verify if this works in the "Discover" application of Kibana. Select your index-pattern there and look for that new `test_scripted_field1` on the left-side. Select it, and see what the results look like.

Hi, I tried the steps provided but I was getting the error on the discover page, and I was not getting any result on the logs. So I have to delete the created field and the log started loading on the discover screen on discover.

Could you please help me to resolve the issue.

Thanks.
