Netmiko logging has issues with ConnLogOnly

[ktbyers]

Basically multiple calls to it will not reinitialize the logging (including the filename)

Also I am doing a getlogger call where name is netmiko.ssh_dispatcher (which is probably not what I wanted).

Also ConnLogOnly fails when used with a Context Manager. I should look to fix that.

Hi @ktbyers,

Does ConnLogOnly suport multiprocessing given the code below?

from multiprocessing import Pool
from netmiko import ConnLogOnly

def main():
    devices = some_function_to_get_devices_and_their_attributes()
    pool = Pool(processes=100)
    data = pool.map(connection, devices)
    
def connection(device):
    device = {
        'ip': device['host'],
        'device_type': device['device_type'],
         'username': device['username'],
         'password': device['password'],
         'global_delay_factor': 4
    }
    net_connect = ConnLogOnly('logfile.txt', **device)
        
    if device['device_type'] == 'huawei':
        command = 'display interface description'
    if device['device_type'] == 'cisco_ios':
        command = 'show interface description'
    if device['device_type'] == 'juniper_junos':
        command = 'show interfaces description'
           
    output = net_connect.send_command(command)
    net_connect.disconnect()
        
    return device['host'], output

        
if __name__ == "__main__":
    main()

ConnLogOnly should support multiprocessing just fine. Whether your code is correct or not, you would need to test.

I would pretty strongly recommend you use Python's Concurrent Futures instead of trying to use the multiprocessing library.
