TELEGRAF ping plugin - best practices

Hi!
I am using inputs.ping plugin to monitor around 500 addresses.
How many IPs should I put in the “urls” configuration? all my list? 100?

[[inputs.ping]]

interval = “5m”
urls = [100 addresses]
method = “native”
count = 10
ping_interval = 1.0

[[inputs.ping]]

interval = “5m”
urls = [100 addresses]
method = “native”
count = 10
ping_interval = 1.0

Regards!
