I'm new to the world of Elastic Search and Kibana and I was asked to create a script that will generate some Kibana visuals (pie charts and bar charts) according to a given argument- a csv dataset. I wanted to ask if that's even possible (with the tools that are supplied by the Kibana software; I searched for an answer but all the explanations that I found were not clear and outdated). If it is, a short explanation, guide or tutorial would be greatly appreciated.
Thanks in advance
Yes this is possible since visualizations and dashboards are basically written in JSON format. There is no detailed tutorial about the syntax of these saved objects. But you should get a good starting point by exporting an already existing dashboard or visualization. This will give you a NDJSON file (new line delimited JSON).
Here's a quick guide to do that:
With that you should be able to figure out which parts have to be variable and which static.
A script could then use a template that fills the variable parts with the data from your csv. After the ndjson file was generated you can import them via the Kibana API described here:
https://www.elastic.co/guide/en/kibana/master/saved-objects-api.html
Please note that there is no function in Kibana itself to generate Visualizations programmatically. You could edit them but not generate them from scratch. So you'd need to write a script/application by yourself and call the Kibana API.
I hope I could help you.
