Quick answers
Frequently asked questions
1What's the difference between the open-source agent and Netdata Cloud?⌄
The open-source agent provides real-time monitoring for a single node via its local web UI. Netdata Cloud aggregates data from multiple agents, offering a centralized dashboard, long-term historical data, advanced alerting, and team collaboration features, accessible from any browser.
2Can Netdata monitor custom applications or services not covered by default collectors?⌄
Yes, Netdata supports custom data collection through its plugin API. You can write simple scripts in any language to feed metrics into Netdata, which then appear on the dashboard alongside built-in metrics.
3How does Netdata handle data privacy and security for the Cloud service?⌄
Netdata Cloud encrypts all data in transit and at rest. Agents only send metadata and anonymized metrics to the cloud by default; sensitive data like hostnames or IP addresses can be obfuscated or excluded via configuration. Access control is managed through user roles and permissions.
4What are the typical resource requirements for a Netdata agent on a server?⌄
Netdata agents are designed to be lightweight, typically consuming less than 1% CPU and 30-50MB RAM on most systems, even when collecting thousands of metrics per second. Resource usage scales with the number of collected metrics and active dashboard sessions.
5Is Netdata suitable for monitoring production environments with high traffic?⌄
Absolutely. Netdata is built for high-frequency, real-time monitoring and is widely used in production. Its efficient data collection and streaming architecture minimize overhead, making it ideal for critical systems where immediate insight is crucial.
