3. | EDGESTATUS (3 Node Cluster Messages) | The leader node is Up, but one of the follower nodes are still down. Cluster is operating at reduced capacity. | Edge Cluster is 'Up', but operating at reduced capacity. 1 out of 3 node(s) are operationally 'Down', with the leader being Up | ERROR |

|
| The leader node is Up, but one of the follower nodes is still “Unreachable“. Cluster is operating at reduced capacity. | Edge Cluster is ‘Up', but operating at reduced capacity. 1 out of 3 node(s) are ‘Unreachable’, with the leader being 'Up’ | ERROR |
|
|
| Majority of the nodes in the cluster are down, indicating that cluster is operationally “Down” | Edge Cluster is ‘Down', operating at reduced capacity. 2 out of 3 node(s) are operationally 'Down’ | CRITICAL |

|
| Majority of the nodes in the cluster are “Unreacahble“, indicating the cluster is “Unreachable“ | Edge Cluster is “Unreachable“, operating at reduced capacity. 2 out of 3 node(s) are “Unreachable“ | CRITICAL |

|
| Leader node is Down, so the cluster is Down | Edge Cluster is 'Down', operating at reduced capacity. 1 out of 3 node(s) are operationally 'Down', leader is Down | CRITICAL |
