Hi, (I´m a new Netdata business cloud customer)

I´m wondering how to configure Netdata cloud to alert me, when a node becomes offline. I couldn´t find any howtos …

Thanks and Regards
Marcels

Hi @MarcelSchober,

You can enable reachable & unreachable notification by clicking on Email Notificationsin the bottom left corner.

And then select for the rooms you prefer, the Reachable & Unreachable option.

Where is this “Email Notifications” button you mention? The screenshot you shared does not match the current Netdata web interface:

Update: Just after posting, I finally found it. For some reason the option is inside “User Settings” rather than the space settings. You click on the profile icon in the lower left, select “User Settings”, then choose the “Notifications” tab.

This is extremely counterintuitive, because the settings page displayed in that pane is very similar to the one displayed under the “Alerts & Notifications > Notification Methods” tab in the space settings, giving the impression that space settings is the right place to look.

Update again: I enabled that setting, saved my changes, and then powered off one of my nodes. However, I received no email notification.

Does this setting work?

Edit: Sigh. I figured that out as well. You have to separately configure notifications for “Reachable” and “Unreachable”. And look at the user interface:

There’s an invisible section you have to scroll down to, in order to find out that “Unreachable” is a separate notification type.

Naturally.

Thanks for following up and for sharing your findings.

To clarify how notifications are structured:

  • User Settings → Notifications
    This area is intended for personal notification preferences, meaning notifications that only affect you as an individual user. This is why certain notification types, such as Unreachable, are configured there rather than at the space level.

  • Space Settings → Alerts & Notifications → Notification Methods
    This section is specifically for space-wide notification delivery methods. These settings determine how notifications are sent to a broader audience, typically through integrations like Slack, PagerDuty, or Email.
    For email in particular, this section only allows enabling or disabling the email integration for the entire space; it does not control individual notification types.

So while the two pages may look visually similar, they serve different purposes: one controls what you personally receive, and the other controls how notifications are delivered at the space level.

Regarding the invisible section you mentioned, you’re absolutely right. That is a UI bug, and I’ve already forwarded it to the frontend team to be fixed.

Let me know if I can assit further.
