Grafana

  • What Grafana version and what operating system are you using?

Grafana 7.5.2.

  • What are you trying to achieve?

I created new panel with Text visualation as HTML.

<html>
<head></head>
<body>
<iframe src=“http://www.google.com” width = 670 height = 510 ></iframe>
</body>
</html>

It should display google page in panel.

  • How are you trying to achieve it?

  • What happened?

Not showing iframe remote page in panel. I changed below configurations but still not displaying page. It gives page not found 404 Error.

I changed /usr/share/grafana/conf/defaults.ini , also changed grafana.ini and restarted grafana server but stillk it show below panel.

enable_alpha = true
disable_sanitize_html = true
enable_alpha = true
allow_embedding = true
cookie_samesite = none

  • What did you expect to happen?

  • Can you copy/paste the configuration(s) that you are having problems with?

I changed /usr/share/grafana/conf/defaults.ini , also changed grafana.ini and restarted grafana server but stillk it show below panel.

enable_alpha = true
disable_sanitize_html = true
enable_alpha = true

The disable_sanitize_html setting is working otherwise you would just see the html as text and not a 404. The 404 is almost certainly happening due to a CORS error.

Google actually doesn’t allow iframing by anyone outside of Google so it won’t work (see this example on StackOverflow). If you change the src to a site that allows iframing then it should work.

Here is an example:

<html>
<head></head>
<body>
<iframe src="https://bbc.com" width="670" height="510"></iframe>
</body>
</html>
