This topic describes how to query the information about an OBServer node by using obshell-sdk-go. One or more OBServer nodes comprise a directed acyclic graph (DAG) task.
Note
We recommend that you read Quick start for a better understanding of how to use obshell-sdk-go.
Considerations
Make sure that OceanBase Shell (obshell) runs normally.
Sample code
The sample code for synchronous task execution is as follows:
package main
import (
"github.com/oceanbase/obshell-sdk-go/services"
)
func main() {
var err error // Handle errors in the production environment.
// Create a client instance, with the IP address of "10.10.10.1" and the port number of 2886.
// Enter the root@sys password "****" for the cluster.
client, err := services.NewClientWithPassword("10.10.10.1", 2886, "***")
// Obtain the information about the OBServer node whose generic_id is 20194912107080886.
node, err := client.V1().GetNode("20194912107080886")
}
