Hi, I have recently customized alerts for the first time. Specifically I changed the “node requires restart after system update” alert to delay for 5 minutes so that it does not fire and then immediately resolve when I am applying an upgrade and rebooting shortly afterwards. I understand that Netdata nodes each have their own alerting configuration, and the Netdata Cloud interface provides a way to apply configuration changes to multiple nodes at a time, so I used this facility to make the same configuration change on all my nodes.
However, the next time I added a new node, by running the suggested command from the “Connect Nodes” dialog, all alerts on the new node are created with the default settings. How can I configure an alerting configuration change to apply also to newly added nodes? Do I have to manually maintain a runbook of alerting changes that I have to re-apply every time I add a new node?
Hi,
To make your custom alert apply automatically to new nodes, set up a Parent node with your 5-minute delay configured, then enable the “Use Cloud for all nodes” (Central Alerting) mode. Every new node you connect will then inherit the same alert settings automatically, no manual steps needed.
You can follow these docs for details:

Thanks! I’m looking through that documentation, but I’m having a bit of trouble understanding what the process is.
I read Parents: Your Centralization Points | Learn Netdata , but while it says “Parents are Netdata Agents that collect and store data from other Agents”, it doesn’t explain how to actually configure a node to be a parent. Is that something that’s done by editing the configuration file on that node? I also looked through the Netdata Cloud interface, but couldn’t find anywhere to configure whether a node would be treated as a “parent”.
I’m also not sure where to find the “Use Cloud for all nodes” option. That sounds like something that would be accessible through Netdata Cloud, rather than in a configuration file, but I can’t find any reference to it in the interface, nor in any of the three documentation pages you linked (other than as a description of how things are configured, rather than something you could actually “enable” as an option).
Would I have to provision and pay for a separate server in addition to the ones I am monitoring, in order to accomplish having the same alert configuration for newly added nodes? I rather expected this to be something I could take care of directly in Netdata Cloud.
