View brokers in a Google Cloud Managed Service for Apache Kafka cluster

Console

1. Go to the Managed Service for Apache Kafka > Clusterspage.

   Go to Clusters

2. Click the name of the cluster.

3. Select the Configurationstab. The cluster's brokers are listed under Active Brokers.

gcloud

To get a list of the cluster's brokers, use the managed-kafka clusters describe command with the --full flag.

 gcloud  
managed-kafka  
clusters  
describe  
 CLUSTER_ID 
  
 \ 
  
--location = 
 LOCATION 
  
 \ 
  
--full  
 \ 
  
--format = 
 "yaml(brokerDetails)" 
 

Replace the following:

• CLUSTER_ID : The ID or name of the cluster.
• LOCATION : The location of the cluster.

The output looks similar to the following:

  brokerDetails 
 : 
 - 
  
 brokerIndex 
 : 
  
 '0' 
  
 nodeId 
 : 
  
 '10' 
  
 rack 
 : 
  
 us-central1-c 
 - 
  
 brokerIndex 
 : 
  
 '1' 
  
 nodeId 
 : 
  
 '11' 
  
 rack 
 : 
  
 us-central1-f 
 - 
  
 brokerIndex 
 : 
  
 '2' 
  
 nodeId 
 : 
  
 '12' 
  
 rack 
 : 
  
 us-central1-b 
 

Kafka CLI

Before running this command, install the Kafka command-line tools on a Compute Engine VM. The VM must be able to reach a subnet that is connected to your Managed Service for Apache Kafka cluster. Follow the instructions in Produce and consume messages with the Kafka command-line tools .

To get a list of the cluster's brokers, use the kafka-configs.sh --describe command with the --entity-type=brokers flag.

 kafka-configs.sh  
--describe  
--entity-type  
brokers  
 \ 
  
--bootstrap-server = 
 BOOTSTRAP_ADDRESS 
  
 \ 
  
--command-config  
client.properties 

Replace BOOTSTRAP_ADDRESS with the cluster's bootstrap address .

This command returns a list of broker IDs, along with their dynamic configuration settings, if any. It does not return the rack property.
