"ping" plugin

Network latency.

Data sources

The network latency is measured as a roundtrip time. An ICMP-echo-request (aka. "ping")is sent to a host and the time needed for his echo-reply (aka. "pong") to arrive is measured. If a reply is not received within one second the plugin will no longer expect a reply and return. This may happen in several circumstances, e. g. the packet is lost, the host is down, a router has dismissed the packet, etc.

This plugin must be configured to work correctly. See below.

Roundtrip time in seconds.

Config options

Host hostname

Hostname to send echo-requests to. If you want to force IPv4 or IPv6 mode you have to give an IP-address here. Otherwise a lookup is performed and the protocol version depends on the address found.
