When Telegraf cannot listen on a privileged ICMP socket it will attempt to use
ICMP echo sockets. If you wish to use this method you must ensure Telegraf's
group, usually `telegraf`, is allowed to use ICMP echo sockets:
On Linux the default behaviour is to restrict creation of ping sockets for everybody. Execute the below command to enable creation of ping sockets for all possible user groups. The integers provided to ping_group_range defines the range of user groups that are permited to create ping sockets, were 2147483647 (the max of a signed int 2^31) is the max group identifier (GID).
```sh
$ sysctl -w net.ipv4.ping_group_range="GROUP_ID_LOW GROUP_ID_HIGH"
$ sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"
```
