Hi

The primary issue is that heat map is not working cause of invalid arguments. I have to add each time "fielddata": true to one of the properties. Robotlogs.json file has been updated but with no positive result.

This has been sorted out by manually typing PUT code in DEVTools.

Is there a way to automate this using Kibana ? I started to think about task directly connecting to the engine and using my script.

Hello,

You will have to do the mapping update directly using Elasticsearch.  
So you using the console is the correct step.

Are you seeing other problems after you updated mapping?

Thanks,

the thing is i have to manually execute PUT command each day so fielddata becomes true

"log": {  
"properties": {  
"instance\_name": {  
"type": "text",  
**"fielddata": true**

i have no clue where i can change this so i dont have to execute this one each day.
