Ping is actually a utility used for testing to see if a node on a network is reachable. It's been around since 1983, and has become ubiquitous with the idea of checking to see if a host or device is up. A ping test consists of sending an ICMP echo request packet to a target and waiting for a response. Ping now means more than just the utility, it also can refer to any use of ICMP echo request packets used for the purpose of testing whether a remote host is up and how long it takes them to respond.
The term has become so widely used to just refer to checking whether a host is reachable that some services use the term when they aren't really talking about a test that uses ICMP packets. That makes it not a ping. In many cases it might not matter much, but if you are testing many network devices, or testing through firewalls and other security devices, it matters. NodePing uses the real thing.
You should use pings when you are checking availability of network devices like routers, and checking if a server is up independent of other services that are running on it. In some situations pings are preferable to HTTP checks because HTTP checks might appear in some statistics systems as hits on the web site.
To set up a PING check,
If you set up a new PING check and it fails from the beginning, please contact your system administrator or hosting provider and ensure PING traffic is allowed to your host
If your host has both IPv4 and IPv6 addresses, you'll need two separate PING checks - one for each.
The maximum threshold/timeout for PING checks is 5 seconds. Any threshold set above that will be ignored.
