Netdata is an infrastructure monitoring and performance troubleshooting solution. Its hundreds of out-of-the-box integrations provide thousands of real-time metrics. This empowers IT and DevOps teams with more knowledge on their infrastructure, helping them improve their root-cause analysis, collaboration, and decision-making.
In this Netdata review, we’ll go over the details of Netdata. What is it, and how does it work. We’ll review its features and user interface. We’ll define a few of its pros and cons. And at the last section, we'll go over the top Netdata alternatives.
What is Netdata?
Netdata is an open-source, distributed, and real-time infrastructure monitoring platform. It keeps track of the performance and health of different environments using a per-second metric approach to monitoring.
With Netdata, you can collect any available metric (on a per-second basis) from your systems and apps using more than 300 agent collectors or the Kubernetes service discovery. You can then visualize all collected data via charts or insights using the cloud-based Netdata dashboard. With access to such data, you can monitor the health and performance with the pre-configured alarms, detect and analyze anomalies, store metrics data for months, and export them to other systems.
- Deployment The Netdata clients can be deployed on Linux, Docker, macOS, or Kubernetes platforms. Netdata Cloud can be accessed via the browser user interface.
- Mobile Mobile app unavailable. Use Netdata via the web browser.
- Customer support and knowledgebase Visit Netdata forums.
- Pricing model Netdata is free and open-source. However, they do provide three plans: Netdata Cloud open-source, Netdata Cloud (free version get it for free), and Netdata Cloud (paid, under-development as of February 2022).
Who uses Netdata?
Netdata is designed for SREs, DevOps teams, developers, sysadmins, or any IT professional that needs to collect metrics from their systems and applications, visualize them in real-time, analyze them, and troubleshoot performance issues. Netdata allows collaboration between teams by sharing dashboards, organizing within war rooms, or assigning roles.
How does Netdata work?
Netdata works through two main elements, the Netdata Cloud and the Netdata Agent. Netdata Agents can be deployed on any single host within the infrastructure and are connected to the Netdata Cloud.
Netdata is based on a scalable streaming application. Each node running Netdata agents can stream the collected metrics (in real-time) to other nodes or a central database. The collected data is only streamed and not stored on the cloud.
What is a Netdata Agent?
Netdata Agents are lightweight monitoring software deployed on distributed assets, such as systems, hardware, virtual, containers, applications, or cloud environments. These agents require zero-configuration, as they are easily integrated and come with auto-detection mechanisms to find data sources.
The agents collect the metrics and forward them to the Netdata Cloud. As mentioned earlier, these agents do not transfer data, only stream it. The agent runs 24/7 and can be installed on popular operating systems, including most Linux distributions, macOS, FreeBSD, and container/microservices platforms.
What is the Netdata Cloud?
The Netdata Cloud is a central cloud-based space that allows you to keep track of all Netdata Agents and their collected data. It shows you real-time data visualizations, including vital metrics, insights, charts, active alarms, and more for all your monitored infrastructure. Although the agent’s data is shown in real-time, the data is not stored on the Netdata cloud but remains on the node. You can access Netdata Cloud via a web user interface.
Key Feature’s Review
- Numerous Integrations Netdata provides hundreds of zero-configuration integrations. You can view thousands of real-time metrics of your APMs, containers, VMs, data stores, logs, network, storage, remote devices, email, web, and many more. Check Netapp’s full integration list.
- Open-source. The Netdata engine is fully open-source software. It is maintained by a strong community of more than 300 contributors.
- Streaming for scalability. Netdata is data-agnostic. It is built for unlimited number, type, and frequency of streamed or collected metrics. Streaming metrics help ensure data privacy compliance, as the data is not sent or stored in the cloud, only streamed.
- Visual and powerful troubleshooting. Netdata collects thousands of real-time granular metrics and presents them in visualizations and charts for easier and faster root-cause analysis. You can spot issues, correlate metrics, and set reactive alerts. Netdata Cloud now is available with Netdata Cloud Charts 2.0
- Out-of-the-box alerting. Netdata comes with hundreds of pre-defined alarms that notify you via email, Slack, Discord, or PUSH actions. You can also customize the alerts. Define dynamic thresholds, role-based notifications, and alarm templates to help the team respond faster.
- Export metrics. You can export your vital or long-term metrics for more analysis or storage—export metrics to other time-series databases such as Prometheus or Graphite.
User Interface Review
The user interface is secure, easy to access and use. You can use your Google or GitHub credentials to access NetData Cloud. Additionally, you can also create an account using your email.
Below is an example of Netdata’s user interface at the start, where you have no nodes. The left-hand menu is the space management area. This area includes submenus like Connect Nodes, Invite Users, Manage Space, Manage War-rooms, Manage Users, and Manage Bookmarks.
To connect nodes to your Netdata Cloud, you’ll need to install the agent’s software on each node. As shown in the screenshot below, the platform gives you the information on how to install Netdata’s agent on Linux, Docker, macOS, or Kubernetes platforms.
You can invite new users to your space by going to the Invite Users area. A new pop-up window will appear where you can send invitations to your team using their email addresses. You can sort users on one or more War Rooms.
The Manage Space sub-menu item allows you to change your space’s name, add a description, and define permissions for invitations and war room creation.
War rooms let you organize your nodes and configure dashboards with real-time metrics and visualizations. They provide segregation in order to improve root cause analysis. When you add nodes to your War Rooms, you can then use the dashboards to keep track of the performance and health of those specific nodes.
To create a War Room, go to the space management area on the left-hand side and click on War Rooms.
Below is an example of Netdata’s “General” War Room. It shows the complete system overview of one node.
Netdata also allows you to build dashboards that pull metrics from any system or number of distributed systems and bring them to a single place. Netdata’s dashboards help you get a bird’s eye view (without having to move from node to node) of the performance and health of your entire infrastructure. They provide good insights to help you troubleshoot or keep an eye on your most vital metrics.
You can create a dashboard from the War Room that you want to monitor. Then, click on the Dashboard tab, and click on the “Green + Add” button. You can add specific nodes or all nodes and assign the context.
