What is '/api/metrics/vis/data' in kibana?

Elastic Stack Kibana
1

I have a proxy server in front of Kibana and I am connecting to Kibana.

However, there are many '502 Bad gateway error' on the TSVB page.
When an error occurs, the request to send is '/api/metrics/vis /data', which api is it?

Is kibana requesting data from elasticsearch?

This API is the data source for TSVB visualizations. It basically takes your TSVB configuration and sends to it the Kibana server which will fetch the required data from Elasticsearch and responds to the Kibana client in the browser with a processed version which is then turned into the TSVB chart you are seeing.

These requests shouldn't error out like this for sure. Could you provide a little bit of context? This will make it easier to find the root cause:

  • The configuration of your proxy server - maybe something's not configured right there
  • The log output of Kibana if something shows up there when these errors are happening
  • Your Kibana/ES version
  • The complete visualization - you can export it by going to Management > saved objects and then exporting the TSVB visualization which is causing the errors

Sure.
Here is my configuration.
However, the proxy settings are unknown.

  • elasticsearch version: 7.6.1

  • kibana version: 7.6.1

  • TSVB is as follows.
    (An error occurs just by entering the tsvb screen.)

Hm, when the Kibana server is not noticing any errors, it is pretty likely the proxy is causing the problem. Can you bypass it somehow to verify whether that's the case? Anyway I would recommend reaching out to the system administrator of the proxy to check the logs there - maybe a timeout has to be increased?

5

The proxy timeout is 30 seconds, and the timeout between kibana and elasticsearch is set to 60 seconds.

The proxy server has the following log. I received an invalid response from the Kibana server ...
However, I can't find anything related in Kibana ....

The information requested by Kibana at the time is as follows.

In this case, where should I check more?

I also want to know the details related to '/api /metrics /vis /data' for exact cause.
Is this request communication between elasticsearch and kibana server?
Or is it the communication between the browser and the kibana server?

I just got the following error, what is this?

This is a request from the browser to the Kibana server. It's an internal API to fetch the chart data (see my description in the first reply).

The browser error from above looks like it's related to the request failing in the proxy. Without more information about the proxy it's difficult to help you.
