I made a a small Monitoring Programm with 2 Subclasses of Threading.

Both running good but when i start my main.py just one thread is executed and the second one is not.

def main():

    #Get SSH connection
    ssh_client = paramiko.SSHClient()
    ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh_client.connect(docker_host, username=username, password=password)
   
    # Threading Event
    stop_event = threading.Event()

    # Creating Threading Objects
    monitoring = Monitor(ssh_client, stop_event, container1, container2)
    query = Query_Servers(stop_event, url1, url2)

    # Start both threads
    print("Start monitoring")
    monitoring.start()
    print("start query")
    query.start()

    time.sleep(40)

    monitoring.join()
    query.join()

#Init Funktion
if __name__ == "__main__":
    main()

What did i miss? The monitoring and query objects are subclasses of Threading. If i comment one of them out other one is running but they don’t run simultaneously.

Can you help me with this ?
