View cluster status

To view the current status of the cluster nodes, run the following command. The command returns information about the cluster nodes, including their master and standby roles, endpoints, status, start time, and synchronization status:

pdbcli status

The following output is returned:

Using config file: ./config.yaml
Cluster Status:
{
    "phase": "RunningPhase",
    "master": {
        "endpoint": "10.XX.XX.1:1521",
        "phase": "RUNNING",
        "start_at": "2020-09-23 21:48:23"
    },
    "standby": [
        {
            "endpoint": "10.XX.XX.2:1521",
            "phase": "RUNNING",
            "start_at": "2020-09-23 21:48:31",
            "sync_status": "SYNC"
        },
        {
            "endpoint": "10.XX.XX.3:1521",
            "phase": "RUNNING",
            "start_at": "2020-09-23 21:48:31",
            "sync_status": "SYNC"
        }
    ]
}

You can also add the --full parameter to obtain complete cluster status information. This information includes the ID, endpoint, port, engine status, and pod status of each node.

pdbcli status --full

To get help information about the command, run the pdbcli help status or pdbcli status --help command:

Using config file: ./config.yaml
Show PolarDB Cluster status.
    
    For example:

    pdbcli status

Usage:
 pdbcli status [flags]

Flags:
   --full         Show complete status information.
 -h, --help     help for status
