Ping (ICMP) monitors

You can now monitor a host or IP address with ping. Each check sends 1 to 5 packets, records packet loss and round-trip times, and you choose how much packet loss counts as down.

Ping suits servers and network equipment that don't run a web server. Some networks block ICMP, so the form reminds you to check that first. The UptimeRobot, Pingdom and CSV importers now bring ping monitors across instead of skipping them.
