MN Monitoring

The Management Node Monitoring (MN Monitoring) feature allows you to view the health status of each management node in a multi-management node environment.

In the navigation pane of the ZStack Private Cloud UI, choose Platform Management > MN Monitoring. Then, the MN Monitoring page is displayed.

As shown in Figure 1.

The MN Monitoring feature displays the management IP address, node status, VIP, and management service status of different management nodes. The management service includes:
  • Whether monitor IP is reachable

    Checks whether the monitor IP address of the active and standby management nodes is reachable. If unreachable, the high availability feature of the management node might be invalid.

  • Whether peer management node is reachable

    Checks whether the standby management node is reachable. If unreachable, the standby management node cannot be communicated.

  • Whether VIP is reachable

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

  • Database status

    Monitors the status of the database. If the database is abnormal or the databases of multiple management nodes are not synchronized, the data might be lost. We recommend that you troubleshot this issue as soon as possible.

Notice

  • The management node area includes three colors: green, red, and gray. Green indicates that the management node or related information is normal. Red and gray indicate that the management node or the related information is abnormal. If red or gray is displayed, perform troubleshooting as soon as possible.
  • The multi-management node environment uses the active-standby mode, and the environment has only one active management node. The active management node displays its VIP, while standby management nodes do not display their VIPs.
  • If all standby management nodes are abnormal, after the active management node fails, services in the active management node cannot be switched to standby management nodes and the active management node is down. Therefore, if you find an exception in a management node, perform troubleshooting as soon as possible.
