Get total number of consumers for a RabbitMQ queue using pika


The following code is what I use to get a count of number of consumers :

import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(host='IP ADDRESS'))
channel = connection.channel()

this=channel.queue_declare(queue="Queue_name",passive=True)

print this.method.consumer_count

Now the count that I obtain are the number of active consumers. However, when consumers are consuming from the queue, this count is printed as zero. Now I need the total number of consumers consuming from the queue. This appears RabbitMQ Management (as consumers : 0 active 25 Total)

Is there a way to obtain a count of the total number of consumers consuming from a queue, while there are messages in the queue?

Thank you in advance


Solution

  • Following is an answer to this question. However, it uses HTTP API and not pika.

    import subprocess
    import os
    import json
    
    
    #Execute in command line
    def execute_command(command):
         proc = subprocess.Popen(command,shell=True,stdout=subprocess.PIPE) 
         script_response = proc.stdout.read().split('\n')
         resp=json.loads(script_response[7])
         print resp[0]['name']
         print resp[0]['consumers']
    
      ######### MAIN #########
      if __name__ == '__main__':
          execute_command('curl -i -u guest:guest http://*IP ADDRESS*:15672/api/queues/')
