### Feature Request ## **Feature Request** ### A concise description of the feature Currently, when adding a Debian Linux node as an **agentless SSH monitor**, HertzBeat requires a **static IP address**. I would like to request support for using **hostname-based resolution (DNS or mDNS, e.g. `node-name.local`)** instead of only IP-based configuration. <img width="1917" height="958" alt="Image" src="https://github.com/user-attachments/assets/9d4f221e-18cf-496b-8220-6e5cfd142338"; /> This would allow monitoring to continue seamlessly even when the node’s IP address changes. --- ## **Is your feature request related to a problem? Please describe** Yes. In our environment: * Debian Linux nodes are added as **agentless SSH clients** * Some nodes receive **dynamic IPs via DHCP** * When the IP changes, HertzBeat marks the node as **DOWN**, even though the machine is still online and reachable via hostname This causes: * False “node offline” alerts * Manual reconfiguration whenever IPs change Using **hostname or mDNS-based SSH monitoring** would solve this issue. --- ## **Additional Context / Use Case** * Environment: Debian Linux (agentless SSH) * Monitoring type: OS / CPU / Memory / Disk * Network: DHCP-based, IPs may change * Hostnames are resolvable via: * mDNS (`*.local`) * or internal DNS **Example use case:** ```text node-01.local → IP changes → monitoring should continue without interruption ``` --- ### Is your feature request related to a problem? Please describe ## **Expected Behavior** * Allow SSH monitoring configuration using: * Hostname (DNS) * mDNS hostname (`.local`) * HertzBeat should resolve the hostname dynamically before each check * Node should not be marked DOWN solely due to IP change --- ## **Alternatives / Questions** If this feature is not currently supported, guidance on **best practices** would also be very helpful, such as: * Recommended DNS/DHCP setup * Any workaround for dynamic IP environments --- ## **Appreciation** Thank you to the HertzBeat maintainers and contributors for building such a **powerful, clean, and user-friendly monitoring platform**. It has been extremely useful for our production and edge environments 🙏 <img width="1919" height="881" alt="Image" src="https://github.com/user-attachments/assets/653d5bb0-70c5-4135-a2be-023368c26915"; /> --- ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
