All these graphs are never really actionable and are only of interest for a short period of time and you won't be looking at it after a while because they don't mean anything unless you know where and when the problem is.

A sever admin wants "Incident" panel that only shows anomaly components at the top coupled with adjustable alerting mechanism and not just a dump of all the data there is blindly.

There are so many tools that does this and pretend it's impressive including ELK but whether it's Grafana or Kibana, you need a lot of manual tweaking to make the dashboards actually useful.

Netdata does have alarms/alerts, and comes with default ones.

Actually, we give a lot of thought in defining sane default alarms for most of the data sources that we have.

We want our users to get 80% of the value with 20% of the effort.

It's an opinionated approach that liberates a lot of users from having to setup and maintain everything.

The only gripe I have with it is the approach to security, i.e. the lack of user accounts (even one). So you have to either block the stats by IP (who is doing it these days?) or use other workarounds like proxying by Nginx etc.

Using Netdata Cloud is a great way not to spend any time with that and access the Agent's dashboard through Netdata Cloud. We use WSS and MQTT, so it's super secure and lightweight. The data are streamed from the Agent directly to your browser via the cloud. Relevant docs: https://learn.netdata.cloud/docs/configure/secure-nodes#disa...

So the only convenient way to have security is to use the cloud version? Got it.

Workarounds like proxying by nginx is not a workaround, it's the industry standard way of managing access to services. It's both more convenient and more secure, a rare combination.

More convenient because you can use your companies pre-existing authentication to authenticate the requests, and more secure because you're not having to manage separate passwords and user accounts.

I write and maintain an open source monitoring tool and I looked into adding a mode to output metrics in Netdata format and ran away screaming. It's just an unstructured text format where you output commands to stdout, one per line. Each command consists of whitespace-separated fields. Which field is the units? Oh, the 4th. And some fields are optional, I'm not even sure how that works but I think you can't skip an optional field if you then want to use any field after that. It's like structured data formats like JSON or god forbid XML never happened.
