Cluster Panel

The Cluster panel shows the live topology and health of an ArcadeDB High Availability cluster, the current leader, and exposes membership-management actions on the leader.

Cluster Panel

The header shows:

  • Cluster Name.

  • A Role badge for the local node (Leader or Follower).

  • A Health badge (color-coded).

  • Refresh button.

  • Auto-Refresh dropdown (Off, 5s, 10s, 30s, 1m).

The panel has three sub-tabs.

Overview

Top info row: Leader name, Leader HTTP address, Local Peer identifier, Server count.

Below it, a grid of Node Cards — one per node — each showing status, uptime, hosted databases and key metrics.

Cluster Overview

Metrics

Summary cards:

  • Elections — number of leader elections since startup.

  • Last Election — timestamp of the most recent election.

  • Uptime — cluster uptime.

Cluster Metrics

Management

Membership and lifecycle actions.

The left column exposes:

  • Cluster Membership — list the current peers and add or remove them. This action is only available on the leader; on a follower the controls are read-only.

  • Bootstrap Baselines — when applicable, shows the per-database fingerprints used to validate new peers.

The right column contains a Danger Zone with the Shutdown This Server button. Shutting a server down is irreversible from the UI; in HA the rest of the cluster keeps running.
