Netdata Reviews

Summary: It's a game changer. It has alerts and real time graphics with several metrics in one tool. Some years ago, you had to install Nagios and cacti or Zabbix to achieve this and config every service. With Netdata you have a good amount of work done.

Positive: Easy to use.
Ready to use after install.
Lots of services configuration ready after install.
Real time graphs.

Negative: Lacks a configuration exporting tool but this is not relevant at all. I can't figure out cons...

Summary: I highly recommend Netdata for teams of any size -- even if you are self-hosting everything. Netdata provides so many automated tools and alerts out of the box in one simplified solution that it blows any other tool I tested out of the water. The only way server monitoring gets easier is if you are outsourcing that service. And I'd argue that outsourced service should use Netdata itself.

Positive: Aside from the automated metrics graphing and alerting in Netdata which by itself is amazing, Netadata can also provide HashiCorp Consul service healthcheck failure alerts automatically by simply collecting metrics through the StatsD protocol -- a wonderful side effect I was not expecting at all and one that I absolutely needed! I was already planning to use Netdata due to all the other monitoring alerts it already provides out of the box, and knowing it can automatically monitor my HashiCorp Nomad integrated with Consul is definitely the cherry on top.

Negative: Container setup can take a few tries since you need to provide the correct mountpoints and other settings scattered throughout the manual, but everything is documented and once done it works wonderfully -- I haven't had a single Netdata instance crash in more than six months of constant monitoring and alerting.

Summary: Excellent for the real-time metrics use case.
Automatic setup makes it easy and quick to install and use with almost zero configuration.

Positive: Second resolution metrics, relatively low overhead of collection.
Default install is very usable, including autogenerated Dashboard.
Extremely flexible dashboard UI: zooming and sliding is shared, as marking a period.

Negative: Mouse scrolling, realtime data, freezing/examining graphs is sometimes clashing, and the user have to put the mouse pointer at a carefully selected part of the screen. :-)
Configuration is a bit weird. Configuring data retention and storage is tricky. Creating centralised server needs a few tries. Logging may be too verbose or terse and no in between.

Summary: Awesome tool that sends me a notification if a server is having problems and has saved me some headaches.

Positive: Fast setup, and a great web interface with some cool features make it a great tool for every server.

Negative: Manual configuration for alerts is needed in the config file, which can be quite the pain.

Summary: Netdata stands out for its exceptional real-time monitoring capabilities. Its ability to provide detailed, immediate insights into system performance is invaluable, enabling proactive management and ensuring stable and efficient operations. While there's room for improvement in reporting functionalities, Netdata remains a vital asset for real-time infrastructure monitoring.

Positive: Netdata's strength lies in its ability to deliver real-time, granular metrics that empower proactive infrastructure management. The detailed insights provided by Netdata enable swift identification of performance bottlenecks, aiding in immediate troubleshooting and ensuring optimal system performance across our infrastructure. Its user-friendly interface and ease of integration further enhance its appeal, allowing for quick deployment and seamless monitoring.

Negative: However, while Netdata excels in real-time monitoring, it lacks certain reporting functionalities that could provide more comprehensive insights into our infrastructure's performance trends. Enhancing reporting capabilities could further augment Netdata's utility by offering a more holistic view of system behavior and aiding in long-term planning and analysis.
