With SmokePing you can measure latency, latency distribution and packet loss in your network. SmokePing uses RRDtool to maintain a longterm datastore and to draw pretty graphs giving up to the minute information on the state of each network connection.
SmokePing can also deal with machines who frequently change their IP address by allowing the remote host to call SmokePings attention to its new IP address. In such a setup SmokePing monitors also for how long the remote system could keep its IP address. To ensure that it is not suddenly monitoring the wrong host, SmokePing further tries to fingerprint each of its Dynamic IP targets via SNMP.
