SmokePing checks connectivity and availability. It is based on the commonly-used Ping utility that is available in every operating system. Ping sends a request packet to a destination address that automatically triggers a response. After several repetitions of this cycle, Ping reports on how many of the packets were replied to and how much time elapsed between the issuance of the request and the receipt of the reply. SmokePing shows a graph of Ping results over time with a sliding window timeframe.
