how can i know the status of a large no of devices (approx 600,000).If i want to moniter the status of the device whether up or down.
Will any scripting language be sutable for such a task because the only way i can think of monitoring these devices from a linux/windows machine is to ping the device status.but again pinging will not be a good idea beacuse it will take a lot of time.
If i need to login and check the status of ports then that would take a lot more time.
what is the best way possible? How many devices can i ping if i use parralell processing?
