Agent-Cloud link (ACLK)

The Agent-Cloud Link (ACLK) provides secure communication between your Netdata Agents and Cloud. This connection:

• Uses outgoing secure WebSocket (WSS) on port 443
• Activates only after you connect a node to your Space
• Ensures encrypted, safe data transmission

For ACLK to function properly, your Agents need outbound access to Netdata Cloud services.

Allowlisting Method	Required Access
Domain	• app.netdata.cloud • api.netdata.cloud • mqtt.netdata.cloud

Important

IP addresses can change without notice! Always prefer domain allowlisting. If you must use IP addresses, be aware that they vary based on your geographic location due to CDN-edge servers. You'll need to regularly verify the IP addresses specific to your region.

Data privacy

Your monitoring data belongs to you. Here's how we ensure this:

• Zero Metric Storage: We do not store any metrics or logs in Netdata Cloud.
• Local Data Control: All your monitoring data stays within your infrastructure.
• Minimal Metadata: We store only essential metadata needed for coordination and access control.

For complete transparency:

• Read our detailed Privacy Policy
• Learn more about stored metadata

Enable and configure the ACLK

The Agent-Cloud Link is enabled automatically—no configuration needed. If your Agent requires a proxy to access the internet, you'll need to configure proxy settings.
