View Management Node Monitoring

Status Description

• The page uses green, red, and gray to indicate status. Green indicates normal status. Red and gray indicate abnormal status.
• Management node HA works in active/standby mode. The node that displays the VIP is the active management node, and the node without a VIP is the standby management node.
• If all standby management nodes are abnormal, failover cannot occur when the active management node fails, which may cause management node downtime.

Management Service Metrics

Arbiter Gateway Reachable

Monitors whether the arbitration IP addresses of the active and standby management nodes are reachable. If the arbitration IP address is unreachable, management node HA may become unavailable.

Peer MN Reachable

Monitors whether the standby management node is reachable. If the standby management node is unreachable, the active management node cannot communicate with the standby management node.

VIP Reachable

Monitors whether the VIP is reachable. If the VIP is unreachable, the active management node cannot access the UI through the VIP.

Database status

Monitors database status. If the database is abnormal, data loss may occur and the fault must be recovered promptly.
