Short: "Latency Diagnostic tool for zt",

Long: `zping replaces the function of icmp ping tool in a zt network.
|
|
It provides an end to end latency measurement between any two zt identities in
|
|
a zt network and like icmp ping will provide the following metrics upon completion
|
|
of the ping session: min, max and mean latency and standard deviation as well as % loss.
|
|
zping uses the addressable terminator function of zt to direct ping requests to
|
|
specific zt identities.`,
