Just saw this in the changelogs:

  • The built-in Netdata UI, accessible from the Netdata button on the Reporting screen in TrueNAS 24.04 and 24.10, is removed in TrueNAS 25.04 (and later) for security hardening. Users wishing to continue using the Netdata UI to monitor system reports can install the [Netdata]application.

Are there instructions for doing this? How do you get the private key? The command they ask to use;

sudo cat /var/lib/netdata/netdata_random_session_id

doesn’t seem to work?

Linked from the release notes they’re quoting: Netdata | TrueNAS Documentation Hub

I’m not aware of any additional shell commands needed to generate a session ID after installing the app. Are you finding the app not working without one?

Thank you for the Tutorial link. Some of the (minor) details don’t match like there doesn’t seem to be a Force flag and the button doesn’t say “Web Portal”. But I think my problem was that when I get down to “Using the Netdata Web Portal” and click on the Web UI, it doesn’t come straight up with the local agent data like in the tutorial, it comes up with the screen in Figure 16. I need to click on “Skip and use the dashboard anonymously” in small type at the bottom every time. If I click to Sign In, I get prompted for a private key from ‘/var/lib/netdata/netdata_random_session_id’ which does not exist.

Is there a way to bypass the cloud login screen?

I’m not entirely sure since I didn’t personally validate that tutorial and the last update to it appears to have been in February, which means some things could have changed since then. Hopefully another user can point you in the right direction.

I found this;

So, apparantly it’s a “feature” implemented with a recent version of Netdata.

Based on the screenshots, the tutorial uses version 2.0.3 of Netdata and the version installed into my TN 25.04 is 2.4.0.

Perhaps the tutorial should be updated, and/or a checkbox added to the app’s configuration that would optionally append the “/v3” mentioned in the article to the URL opened by the “Web UI” button.

Good idea :wink:

That will be included in this PR.
