Differences console and UI in ELK

[soodabehzz (Soodabeh Zarezadeh)]

Hi everyone
I use kibana with elasticsearch, now I am learning the ML part.
Is it possible help me know, there is any different between creating job by UI compared to console, I think the console has more feature and if the answer is yes, where I can find some example?
I couldn't find any proper example to learn.
Thanks

Hi,

Yes you can use the Machine Learning APIs in console the documentation is a good place to start.

The APIs are useful if you want to automate the creation of jobs or stopping/starting datafeeds. If you are getting started with Machine Learning I would stick to the UI it has all the features you need.

Thanks for ur reply.
so you say there isn't any different between UI and ML API?
and another question
I got an error when I want to start a datafeed, as beloww:
"datafeed [datafeed-total-requests] cannot retrieve field [timestamp] because it has no mappings"
I create and start datafeed by below code:

PUT _xpack/ml/datafeeds/datafeed-total-requests
{
  "job_id": "total-requests",
  "query": {
      "match_all": {}
    },
    "indices": [
      "server-*"
    ],
    "types": []
}

 `POST _xpack/ml/datafeeds/datafeed-total-requests/_start

My job is open and the "server-*" index has stored in elasticsearch before.
Thanks
