JSON Input - get RIGHT characters from string


(Simon Singh) #1

I'm using Kibana 6.4 and am trying to get the rightmost characters from a string using the JSON Input in a visualisation. I can successfully do this:

{"script":"_value.substring(0,8)"}

But can't seem to find any documentation on the string functions available. Is there any documentation on what we can do with JSON Input?

You shouldn't be using the JSON input for scripts. The best way to do it is by using the scripted fields option already available in Kibana. You get a detailed guide in that page and a way to test everything based on your data.

Thanks Marius,

Is there any documentation to explain when we should be using JSON input? I'm struggling to understand how and when it should be used.

Thanks
Simon

It's usually for adding extra query parameters that aren't exposed in Kibana, for particular cases. It works for everything else, but scripted fields.
