Add server

Reading Time: < 1 minute

When to use

The page describes the startup script of the addition new servers to an existing Vezha cluster via a one-time OTP.

What to prepare

  • Access to the desired cluster in Vezha.
  • Access to the target server with administrator rights.
  • The selected license for the server (if you need advanced capabilities immediately after connecting).

Steps in UI

  1. Open the cluster and start adding a server.
  2. Generate OTP.
  3. Copy the value: CLUSTER_ID, OTP, endpoint, ingress-endpoint.

Steps on the server

  1. Download the agent for your OS.
  2. Run the join command with parameters from the UI: Join by OTP.
  3. Install the agent as a service: sudo ./vezha-agent install.

Important

  • OTP has a short TTL (10 minutes in the current implementation), so don’t delay the command.
  • If the server is reinstalled, use reconnect instead of rejoining the new node: Reconnecting the server.

What to check after adding

  • The server is displayed in the cluster list.
  • Live metrics are coming.
  • The actions in the server card correspond to the assigned license.
